A Builder in CDMX: Flu Edition

Earl Grey — Sun, 08 Nov 2026 01:45:07 +0000

I built my sick wife a digital bell. She pressed the one button I left blank.

TL;DR: I caught the flu in Oaxaca and I still have it. By Mexico City, my wife had it too. From a tired Chromebook, I directed Claude to build her a sick-day bell: a page of big papel picado buttons where tapping "Té, por favor" opens a text to me, already written. No IDE, no terminal: Claude pushed it to GitHub straight from the chat, and it took under an hour from idea to her first tap. Her first tap went somewhere I didn't plan for.

My last post in this series ended with "Oaxaca is next." It was. I just didn't plan on leaving it with a fever.

So here's the setup. We're on vacation in Mexico. I got sick in Oaxaca a few days ago. We made it to Mexico City, and then it was E's turn. I'm still sick. Now she is too. So she's in bed, and I'm the one pushing through, upright enough to fetch things.

I was proud of one thing on this trip. I didn't touch my Chromebook until day 8. I was going for an all-time record. Then E got sick, and she was napping, and, well. I couldn't help myself. Okay, I could have. I didn't want to.

What I had: an HP Chromebook 11a with a MediaTek Kompanio 500 processor and 4 GB of memory, 1.44 GB of it free. A keyboard I kept fighting. It's an 11-inch layout after years on my 17-inch laptop at home and my work keyboard, so my fingers kept landing where the keys used to be. My messages to Claude that night included "spik ebut" and "ato home." It read them anyway. A few hours. What I didn't have: my usual setup, or any energy for a real project.

Because E was sick in bed, I thought she might need a bell: the little one you ring to ask for tea or a blanket when you don't have the energy to call out. Neither of us packed one, so I built her a digital one, hosted on GitHub Pages (here's the repo). Same job, fewer jingles.

I asked Claude (Opus 5.5) what we could build. It gave me three options. A play-test spike for my Kiroween typing game, which the bad keyboard would turn into free user research. A small sick-day page for E. Or a pure vacation toy.

It recommended the spike. I picked the page for her, because it was lovely and the spike could wait.

The Chromebook turned out not to matter. Claude works in a cloud workspace, so the heavy lifting happened there. When I checked the laptop afterward, its CPU was sitting at 5%.

The memory was mostly spoken for. The processor was barely awake. My job was the same as always: direct, decide, say no to things. On that keyboard, saying no was about all I could type anyway.

Under an hour later, my phone buzzed. The first text from her new bell was blank.

She rang the blank one

E had opened the page, skipped past the tea, the water, the blanket, and the soup, and tapped the one button with nothing written on it: Otra cosa, something else. Her Messages app opened, empty, pointed at me. She wasn't sure what to do with it. So she went back and tapped tea.

That one came through with a little steaming cup: 🍵 Té, por favor (Tea, please).

Same page, same person, two very different taps. I'll come back to the blank one. First, how it got built.

Five questions, zero typing

I asked Claude to interview me about what E should see. It asked one question at a time, each with options I could tap instead of type.

Question	What I picked
Which buttons?	Tea, water or juice, extra blanket, come sit with me, a blank "something else"
Any more?	Soup or something to eat, lights down and quiet
Look and feel?	Bakery warm, then papel picado (more on that below)
Pictures?	Big emoji, small words
What's at the top?	A Spanish touch: ¿Qué necesitas, mi amor?

That interview is the whole spec. Seven buttons and a greeting. I didn't write a PRD for this one, and I'm at peace with that.

A button is just a link

Each button is a plain link in the format iPhones accept for texts: sms:NUMBER&body=TEXT. Tap it and Messages opens with the number and the message filled in.

See the screenshot full size, or browse the code in the necesito repo.

She still has to press send. A web page can't send a text on its own, and I'm glad it can't. That one tap is a small price for a page that can't text anyone without her knowing.

The text that lands on my phone is the notification. No app for me, no server, nothing to keep running while we're both sick.

Spanish first, with training wheels

We don't speak Spanish. But we're in Mexico City, and ¿Qué necesitas, mi amor? is a much better thing to see from bed than "Request Form."

So the page went Spanish first, with a small English line under every label so she always knows what she's tapping. The texts come through in both: 🛌 Otra cobija, por favor (Extra blanket).

The first theme was bakery warm, a nod to her bakery. Then I asked to explore Mexican palettes, and we landed on papel picado: rosa mexicano, turquoise, orange, lime, purple, and marigold, with a string of cut-paper flags across the top.

The flags are pure CSS. On the first pass, the cutouts were arranged so each flag looked like a little smiling ghost. Claude rearranged the holes into a flower pattern. Now they look like papel picado instead of a haunted bunting.

Toe pick.

Claude filled in my number so the buttons had somewhere to send. Then we made a public GitHub repo, because free GitHub Pages wants one. Then it hit me, and I typed "TOE PICK!"

(If you know, you know. The Cutting Edge, 1992. The hockey player. The figure skater. The fall.)

My phone number was sitting in two files and the commit history of a public repo. It got there by me saying yes to each step without seeing where they added up.

The fix Claude proposed: take the number out of the code entirely and put it in the link instead, after the #.

https://earlgreyhot1701d.github.io/necesito/#5551234567

The part after the # is called the fragment, and browsers keep it to themselves. They don't send it to the server (RFC 3986, section 3.5), so GitHub never sees it. A few lines of script on the page read it, accept it only if it's 10 to 15 digits and nothing else, and build the buttons from it. A link with no number, or junk instead of digits, turns the buttons off and shows a note asking her to get the link again.

Then Claude wiped the history down to one clean commit and force-pushed it. One honest caveat: GitHub can keep an old commit reachable for a while to anyone with its exact address. Nobody had it, the repo was minutes old, and I can live with that.

The trade-off: the number lives in the link, so anyone she forwards the link to can see it. She's not forwarding it. She's resting.

No IDE. Just a chat.

This is the part I keep thinking about.

My usual build has handoffs. Claude writes the spec, Kiro builds it in an IDE, I review and decide. Tonight there was no handoff. I never opened an editor or a terminal. Nothing got installed on the Chromebook.

Once I created the empty repo and approved access, Claude cloned it, wrote the files, took screenshots to check its own work, committed, and pushed to GitHub. All of it happened in the same chat where it was asking me about tea. Every commit in the repo came from that conversation. !!!!!!!!!!!!!!!!!!!!!!!!!!!

There were two things it couldn't do, and I like knowing where the edges are. It couldn't create the repo for me, and it couldn't turn on GitHub Pages, because that part of the GitHub API is blocked from its side. So I clicked those, about a minute of work, and Claude did everything else.

That split felt right. I owned the account decisions. The agent did the typing I couldn't.

The extras came after:

File	Job
`og.png`	Social card, so iMessage shows the papel picado preview instead of a bare link
`apple-touch-icon.png`	A tea-cup flag icon for the browser tab
`robots.txt`	Keeps search engines out. It opens with "Shh. Someone's resting."
`humans.txt`	Credits. E's role: "resting. Tapping buttons. Getting better."

Why the blank one stays

Back to that empty text.

The blank button was a choice, not a gap. Sometimes what you need isn't on the list, and the person in bed should still get a way to ask. But a blank text with no prompt left her unsure what she was supposed to do next. The pre-written buttons worked on the first try, with the cute emoji and everything.

So v2 gets one change: Otra cosa opens with Necesito... (I need...) already typed, so the cursor lands in a sentence instead of a void. That's it. Not refactoring anything else from a sick bed.

What it can't do

Send the text for her. She presses send, every time.
Work on Android as written. The link format is iPhone-first; Android usually wants ?body= instead of &body=. Untested there.
Hide the number from anyone who has the link.
Tell her I read it. It's a request button, not a pager.
Work without a signal. If Messages can't send, the page can't either.

This is the third stop in the A Builder in... series. In Paris, I learned that stepping away from my desk doesn't mean I stop building. In New Orleans, an app I'd already built came on the trip with us. Mexico City is the first time the app got built on the trip, for one person, for one sick week.

The goal on every trip is the same: close the laptop, let the internet go on without me, and leave the FOMO at home. It’s never easy. This time I made it to day 8. Next time, day 9.

Quick context if you are new here. I work in the California courts, running court operations for the county. I started building with AI in July 2025 and I have been learning in public ever since. I do not write the code. I direct, the agents generate, I validate and decide. I build the Clew Suite, a set of civic tech tools for making complex systems easier to inspect. That is the lens I am writing from.

Built and written with AI assistance in November 2026. Claude (Opus 5.5) wrote the code, pushed the repo, and assisted in draftingdthis post from our build session. I directed, decided, and edited.

From One Chatbot to Five Agents: My AWS Agent Engineer Nanodegree

Earl Grey — Fri, 30 Oct 2026 18:14:42 +0000

TL;DR: I finished the Future AWS Agent Engineer nanodegree with three graded projects, each a customer support system for a fictional online store: one chatbot, then one agent, then five agents working together. Each project was harder than the one before and gave me fewer problems, because every mistake became a check in the next build. Here's how the three compare, what changed between them, and why the last one, which scored 120 out of 120, still got sent back for more proof before I passed the project.

My first project for this nanodegree went in on deadline day in August. It was a chatbot with one system prompt, graded by a rubric written for a product AWS had already stopped offering to new customers. It passed. I spent most of that day worried it didn't count, because I hadn't typed the code.

My second project went in a month later, built in one session. It was one agent that could look up orders, process refunds, and search a product catalog, with an ownership check in code so it wouldn't show you someone else's orders. It also introduced me to a database that bills by the hour just for existing.

My third project went in on a Sunday night in October. It had five agents, two models, three knowledge bases searched at the same time, and a safety filter on every model call. It went from Udacity's untouched starter files to a perfect score on its test suite in under four hours.

Each project was harder than the one before, and each one gave me fewer problems. I didn't expect that, and I wanted to understand why, so this post compares the three side by side.

A junction, a helper, a council

The AWS AI & ML Scholars program runs with Udacity. I was in the Agent Developer track, and its nanodegree, Future AWS Agent Engineer, has three graded projects. All three are customer support systems for a fictional online store. Because the problem stayed the same, I could compare the three builds directly, each one with more tools than the last.

All three ran on Amazon Bedrock AgentCore, AWS's managed service for the parts of an agent you would otherwise build yourself: calling the model, remembering the conversation, running tools, and hosting the whole thing.

Project one was Nova Trivium, and I wrote about it in Future AWS Agent Engineer? I Didn't Write the Code. Does It Count?. A trivium is where three roads meet. One system prompt sent every message down one of three paths: file a bug report, answer from a pasted FAQ, or redirect to a human.

Project two was Nova Adiutrix, written up in Nova Adiutrix: my second agent built my first project's to-do list. An adiutrix is a helper. One agent tracked orders, processed refunds, searched a product catalog stored in a knowledge base (a managed store the agent can search by meaning instead of exact words), and refused to show you someone else's orders.

Project three is Nova Concilium. A concilium is a council. Five agents, each a specialist, with an orchestrator deciding who speaks.

earlgreyhot1701D / nova-concilium

Nova Concilium: a five-agent customer support system on Amazon Bedrock AgentCore and Strands. A Haiku orchestrator routes to Sonnet specialists for inventory, refunds, policy, and replies, with parallel RAG across three Knowledge Bases, shared DynamoDB state, Bedrock Guardrails, and X-Ray tracing. AWS nanodegree capstone, 120/120.

Nova Concilium — NovaMart Multi-Agent Customer Support

Status: submission README for the nd905 Course 4 final project — complete with the full 120/120 test run and both X-Ray screenshots recorded below. This file is the submission README; the original Udacity starter README is preserved in the git baseline commit 7ea6508 (unmodified starter). Account ID and runtime ARN are intentionally omitted (redacted for public sharing).

Nova Concilium (Latin for "council") is a five-agent customer-support system for the fictional e-commerce company NovaMart, built on Amazon Bedrock AgentCore and the Strands Agents SDK. An Orchestrator agent routes each request to specialist worker agents, retrieves grounded policy answers with parallel multi-agent RAG across three Knowledge Bases, enforces a Bedrock Guardrail, keeps shared state in DynamoDB with optimistic locking, and is observable end-to-end through CloudWatch and X-Ray.

What it is

NovaMart's support team handles order status, returns and refunds, and policy questions by…

Here is how the three compare:

The row I'd read first is "How I knew it worked." The testing got stricter with each project, and the stricter the test, the more I trust everything else in that column.

Each project paid off the last one's list

At the bottom of the Nova Trivium README, I wrote a section called "Not built, and why." It listed three things I left out: retrieval, guardrails, and structured output.

Nova Adiutrix built two of them without my planning it. I noticed halfway through, rereading my old README. That post ended with this: "The third item on that 'Not built, and why' list was guardrails. Still not built. I will let you know how project three goes."

In Nova Concilium, guardrails were a graded requirement. Amazon Bedrock Guardrails is a filter that checks what goes into and comes out of the model. Ours blocks competitor talk, price haggling, and legal threats, and it masks personal details. The first sign it worked came from a test that wasn't about it. A customer's email address came back in a test transcript as {EMAIL}.

That finished the list. I didn't pick the order the items got built in. The course did.

The friction moved outward

All three builds had problems. What changed was where the problems came from.

Every lesson showed up again

Here is where each earlier lesson landed:

A knowledge base before a spec

The change I'd credit most happened before any code got written.

On the earlier projects, I handed Kiro a build spec. This time I had Claude, Anthropic's AI model, write a knowledge base first: one markdown file holding every course page, the rubric, the starter repo, and a table of every place those sources disagreed with each other. There were 13. Then, before any spec, Kiro read the starter files and checked all 13. Eleven resolved against a file. The other two had no file to check: a set of names the code hadn't defined yet, and the due date.

Checking the files before writing the spec came straight out of Nova Trivium, where I planned around a starter I had never fully listed. Every value also had to name the file it came from, or get marked UNVERIFIED.

The work split three ways, the same as before. Kiro wrote the code. Claude (Opus 5.5) wrote the knowledge base and reviewed each stage of Kiro's spec against the starter files. I directed, did the Console work, took the screenshots, and made the calls.

Claude's reviews caught four problems in Kiro's requirements. The folder wasn't a git repo yet, so two checkpoints couldn't run. One test was scheduled before the deploy it depends on. The guardrail tests needed example prompts that no file supplied, so Kiro would have had to make them up. And two agents could only be checked after the deploy, so Claude suggested checks that could run earlier.

I over-gated it, then I didn't

The first plan had Kiro stop after every single task and wait for my approval. Early on, I told Claude to stop over-constraining the build. I appreciate thoroughness, but I needed to keep moving.

We cut the stops down to four, the moments that needed me or cost money: before I created the knowledge bases in the Console, before the first deploy, before any git push, and before teardown. Everything else, Kiro ran straight through, pasting output as it went.

The whole run from bare starter files to a perfect score happened after that change, in under four hours. I think the fewer stops are a big part of why it went that fast.

Two agents, one penny

One of the three graded test scenarios asks: how much are 5 items at $29.99 with 10% off?

The exact answer is $134.955, so it has to be rounded. In the latest run, the orchestrator worked it out as $134.96. Then it handed off to the Communication agent, which rounded the discount to $15.00 first and wrote $134.95. The final reply said $134.95. In an earlier run of the same test, the final reply said $134.96.

The rounding rule in the starter code sits in the orchestrator's instructions. The Communication agent, which writes the reply the customer sees, rounded early anyway. As far as I can tell from the logs, the orchestrator's math never made it into the shared record the agents read from, so the Communication agent did the math again its own way.

The test passed anyway. When we wrote the acceptance check, Claude pointed out that the answer depends on rounding mode and suggested accepting either $134.95 or $134.96, since the graded behavior was that the guardrail didn't block a math question. I agreed. Accepting either answer fit the rubric, and it's also why a one-penny disagreement between two of my agents got through every test. Nobody noticed until I read the logs for this post.

This is my second penny this month. In Eight Minutes to Live. Was It Cursor, or Was It the Spec?, a tip calculator I built with Cursor split a 1,437.50 bill three ways into 479.17 each, which adds up to 1,437.51. The extra cent floated because my spec never picked a rule for it.

The comments on that post did more for me than the post did. flatin.pt suggested keeping money in whole cents and handing out the remainder one cent at a time in a fixed order, so the shares always add up. Matt Busel suggested treating the spec as a hypothesis instead of a contract, and updating it every time a check finds a gap. Vlad Zoff suggested keeping the acceptance checks separate from the build, so whoever builds the thing can't redefine what it's judged against.

Vlad's point lands closest to this penny. Loosening the check to accept either answer was a reasonable call for the rubric, but it was still the people building the thing changing the test. Both pennies came from the same gap: in the tip calculator, no rule said who gets the extra cent, and in Nova Concilium, no rule said whose number is the final one. If I follow Matt's advice, the next spec names one agent as the owner of any calculation and has it save the result to the shared record before anyone writes to the customer.

Perfect score, not enough proof

I submitted Nova Concilium that night. The reviewer sent it back less than an hour later.

The feedback was kind. It said the code was a good example of modular, well-documented agent code. Then it asked me to fully deploy my solution, including all the Knowledge Bases and the AgentCore deployment, and to include screenshots of each. Everything it asked for was already deployed and running in my AWS account. The reviewer had no way to see it.

The written deliverables were the code, the knowledge bases, the populated config file, a screenshot of the test score, and a screenshot of the X-Ray service map, which draws every request's path through the agents.

I submitted every one of them. No page asked for Console screenshots or test-run output.

The gap was still mine to catch. The original requirements Kiro wrote said every checkpoint's output gets saved to an evidence folder. When we sped up, the results went into the README as text. Claude didn't flag it in review, and I approved the submission without checking that line. Human approved means the miss is mine.

There's a second lesson in that miss. The rubric says the knowledge bases were "created in the AWS Console" and the system was "deployed to AgentCore Runtime." A reviewer can't log into my account, so for those two lines, a screenshot is the only proof they get. My checklist asked whether each thing was done. It needed to ask whether someone outside my account could see that it was done.

I added the Console screenshots and the test-run output and resubmitted. It passed, and on October 27 the certificate arrived.

Before my course access ended, I had Claude help me turn every lesson into notes: four markdown files, one per course. I wanted to take the knowledge with me, into future builds, instead of losing it when the classroom closes.

What the three projects still can't tell me

Whether my process holds up on a project with no starter files to check against.
Whether a 120-point suite measures what a customer would care about. It didn't catch the penny.
How many of the fights on Nova Concilium were easy only because the first two projects already hurt. ## Does it count?

The first post in this series asked whether directing agents counts as learning, when I never typed the code.

Three projects in, I can name what I learned. I learned where the knowledge lives, where the rules get enforced, and how to write a check that an agent can't talk its way past. On the last project, I learned that a perfect score and a passing submission are different things.

The difficulty went up every time. The building got easier every time. The lessons table is my evidence for why. Seven lessons, each one learned when something broke, and each one built into the next project as a check. That's the skill these three projects gave me: making the next build break in fewer places. I would like to hear from anyone who has built the same thing three times and seen something else.

The certificate says it counts. And..so do I.

Built with AI assistance in October 2026. Kiro wrote the code, and Claude (Opus 5.5) wrote the knowledge base, reviewed the spec, and helped draft this post. All three repos are public, so check them before you quote me.

El Altar que Habla: A Día de los Muertos Ofrenda Built with Gemma 4

Earl Grey — Thu, 29 Oct 2026 04:10:22 +0000

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 4: Ghost in the Machine

I’ve loved Día de los Muertos for 30 years. I had two days to build something for it.

TL;DR: I built El Altar que Habla, an interactive bilingual ofrenda where you choose one of seven traditional offerings and learn what it means, then ask your own question in English or Spanish. Answers come from Google's open-weight Gemma 4, grounded on a curated knowledge base the server controls. When Gemma is unavailable, a labeled curated guide takes over, so the altar still speaks.

What I Built

I was 17 in 1996 when Día de los Muertos found me. I grew up in the United States, and the celebration has been part of me ever since. I am proud of it, and proud of the connection I have to it.

In 2014 I went to Oaxaca for the first time. It was magic. Mexico during Día de los Muertos is magic, always.

So when this week's theme asked for something that honors the past in the spirit of Día de los Muertos, I didn't have to look for an idea. Of course I wanted to spend weeks or months crafting this piece by piece. The challenge timeline gave me about two days. So I made a small offering of my own: a few of the things I have learned over the years, from me to you.

El Altar que Habla means "the altar that speaks." It is an illustrated ofrenda with seven offerings:

Select a + on the altar, or pick from the list, and a story card opens. Each offering has three tabs: Context, History, and Variations. Variations matters most to me. Families in Oaxaca, Michoacán, Puebla, and across the United States don't all build an altar the same way, and the app says so instead of pretending one practice is the rule.

Below the tabs, you can ask your own question. That is where the altar speaks.

Demo

Live: el-altar-que-habla.vercel.app

Try the water. Switch to Spanish and ask "¿Por qué se pone agua en la ofrenda?" When I asked, Gemma answered that water is a gesture of hospitality for souls after a long journey, then added that how it is presented can vary with each family's and community's traditions. That line traces back to the curated context I gave it.

Code

How I Built It

This build went through more hands than I planned.

The model only gets what the server gives it

The open-source AI here is Gemma 4, Google's open-weight model family. I used gemma-4-26b-a4b-it, served through the Gemini API. It answers visitor questions about one offering at a time.

One of my requirements from the first draft of the PRD was primary sources. The cultural explanations draw on Mexican cultural institutions and UNESCO, and the PRD says Gemma may explain that approved, cited content but should not generate new historical or cultural claims.

That requirement shaped the risk I worried about most: a confident answer about a living tradition, with an institution's name next to it, when that institution never said it.

So the browser doesn't send cultural context. It sends three things: which offering, which language, and the question. The server checks the offering against an approved list, the seven offerings I signed off on in the PRD, then builds the prompt from its own curated knowledge file. The question is the only part a visitor controls, and it goes in as a question, not as context.

if (typeof offeringId !== "string" || !Object.hasOwn(APPROVED_OFFERINGS, offeringId)) {
  return res.status(400).json({ error: "Invalid or unsupported offering ID" });
}

The sources get labeled for what they are. The app links to INPI, INAH, UNESCO's listing for Día de Muertos, and the State of México. Every Gemma answer says those links are background reading. They don't verify the sentence the model just wrote, and I didn't want the page to imply they do. @sidswirl's post on source-grounded hallucination checks put words to that worry better than I could.

One more disclosure lives on the page: the altar artwork is AI-generated concept art, not a photograph of anyone's family altar.

The altar still speaks when the AI doesn't

I kept coming back to one rule: even if Gemma falls back, the experience has to hold.

If the model times out or is down, a curated guide answers instead, labeled "Curated guide (no AI)" in its own readable card. Gemma answers get their own label too. That way a visitor can tell which voice they are hearing. Kiro tested the fallback by forcing the model to fail locally, in both languages.

The painted plus signs lied

The first version was one 469 KB HTML file, with the artwork, styles, and both languages all inside it. That breaks one of my own rules: one file, one responsibility. I built it that way on purpose, as a reference point for the look and feel I wanted to protect. It stays in the repo as a baseline, and Google Antigravity, an agent-first coding tool, split it into separate modules from there.

It looked beautiful. Then I asked Codex for a deliberately harsh QA pass. It scored the app about 5 out of 10 and marked production readiness as failing.

That stung. It was also useful, because now I had a list instead of a feeling.

My favorite finding: the altar artwork had plus signs painted into the image itself. The clickable hotspots were separate elements on top. So you'd see a + that did nothing, sitting right next to a + that worked.

The artwork got cleaned. The hotspots got tied to the image's own coordinates. Then Playwright, the browser testing tool, started checking that every hotspot's center lands inside its painted object on mobile, tablet, and desktop, that each one is at least 44 by 44 pixels, and that none overlap. A test that only checks the page's code could pass the broken version.

"Fixed" wasn't the finish line

Antigravity kept telling me fixes were done. I'd open the app and see the same problem. I don't know what happened inside the tool. I know the assurance and the screen didn't match, so I stopped treating "fixed" as the end and started treating my own eyes as the test.

Then Antigravity froze, more than once, and I moved to Kiro, an agentic IDE. Switching didn't mean starting over. The audit findings, a reviewable pull request, and the test expectations gave Kiro something concrete to check instead of a conversation to reconstruct.

Who did what, by the end:

Even after tests passed, my screenshots kept finding things. Story text was bleeding into the question box. That one turned out to be measurable: a text block that needed 42 pixels of height was getting squeezed into about 13. The fix let it keep its natural height, and a regression test now checks for that collision.

The final pass, PR #3:

Kiro confirmed the live site is serving the exact merge commit it reviewed, not just a green "Ready" badge.

Why Does Open Innovation Matter?

An ofrenda is built to be passed down. I wanted the model inside this one to be something that could be passed down too.

For this version I called Gemma through Google's hosted API, because I had two days. But Gemma's weights are public, which means the thing answering questions about my altar is a model anyone can download, run on their own machine, and inspect. If the hosted endpoint changes its terms or disappears, the altar doesn't have to go quiet. With a closed model, I wouldn't have that option.

It also matters for who gets to build these. A community group, a cultural center, a teacher in a classroom with no budget for API bills could run a model like this locally and keep their own families' stories on their own hardware. I didn't build that version. I'd like to.

My Agent Session

I don't have a DevRelay embed for this one, but I do have receipts.

After the freezes, I opened a new Antigravity session on Gemini 4 Argon, a trial model, and asked it to look back at what went wrong. It dug through its own local conversation logs and reported which model each session had run on:

It found two traps. In one, the agent started a preview server in the background and then ended its turn waiting for it to finish, which a running server doesn't do on its own. In the other, on Windows PowerShell, curl is an alias for a different command, and a flag that looks harmless left it stuck waiting on input.

Its theory was that the low reasoning effort in the first two sessions made the first trap easier to fall into. That is Antigravity's read on two sessions, not a proven cause. Then it wrote itself three rules it says it now follows in every session: never end a turn waiting on a background server, always call curl.exe with a 10-second limit, and never pipe binary files through PowerShell's input. No black box there. I loved that.

The Spirit of It

Día de los Muertos is shared remembrance. Families build altars to welcome home the memories of the people they have lost, and the traditions get passed on, from one generation to the next and from one community to another.

The moment it landed for me was that water answer. A model, grounded on what I chose to give it, told a stranger that the way you place a glass of water depends on your family and your community. That is what I have learned over the years, and it came back out of the machine in Spanish.

This week wasn’t about agents or tests for me. I got to take something I have loved since I was 17 and pass a little of it on to a community I love, one made of people from many cultures, with many ways of remembering. A small offering, rough at the edges, built fast. Built with care.

If you build an ofrenda this year, I’d love to hear what goes on yours. And if your family remembers its people in a different way, I’d love to hear about that too.

Prize Categories

Best Use of Gemma: Gemma 4 (gemma-4-26b-a4b-it) answers visitor questions in English and Spanish, grounded on a server-controlled curated knowledge base, with a labeled non-AI fallback.

What it can't do

The curated fallback was tested by forcing failures locally, not by breaking production.
Mobile and tablet checks ran in Chromium emulation, not on physical devices.
The rate limiter is per server instance, so it is best effort, not global.

Seven offerings is a beginning. A family altar holds far more than this one does.

Quick context if you are new here. I work in the California courts, running court operations for the county. I started building with AI in July 2025 and I have been learning in public ever since. I don't write the code. I direct, the agents generate, I validate and decide. I build the Clew Suite, a set of civic tech tools for making complex systems easier to inspect.

Google DevFest Central Valley: Community First, Buildathon Second.

Earl Grey — Sun, 25 Oct 2026 20:56:48 +0000

TL;DR: My second DevFest Central Valley in Modesto was about who AI is for, from the mayor's opening to a keynote on AI as a community institution. In the buildathon I made Onceover, a first-look accessibility checker for small business websites, built in Google AI Studio with Gemini. It tells an owner what it found, where the rule comes from, and what it can't see.

Modesto Mayor Sue Zwahlen stood at the front of the room on Saturday morning and said something most officials wouldn't. She doesn't always know the how of technology. She knows the why.

Then she told a room full of developers, students and the plain curious: we need you.

That was the start of my second DevFest Central Valley, hosted by GDG Modesto with GDG Stockton, GDG Turlock and GDG Merced. GDG stands for Google Developer Groups, the local chapters that run these events. DevFest is their yearly community conference. The theme this year was Build. Scale. Secure. There were talks, labs, a scavenger hunt, and a short buildathon. I came for the buildathon. I'm writing about the room.

Know the why

The mayor's point stuck with me because of how she framed it. When people show up and share what they know with each other, tech grows in a community. That kind of collaboration can change things. She didn't need to understand a model to understand that.

I work in the California courts. Most of the people I build for don't know the how either, and they don't need to. They need the thing to work, and they need to trust it. Hearing a mayor say that out loud, in a room built for builders, set the tone for the day.

AI is an institution, so how do we take part in it?

Saphonia Foster's keynote was on leveraging AI for socio-economic justice. She described AI as an institution, like a library: something that holds and shares knowledge, and that a community gets to shape by how it shows up.

Her framework had three parts, and I wrote them down fast:

Lens	Her question
Time	Are we spending our time with AI productively, or losing it there?
Voice	Are we using our voices to shape AI and AI policy?
Value	Are we using AI to lift up our communities, guided by our own perspectives?

I kept running my own work through it. For a small business owner, time is the whole budget. Voice is whether the tools she uses explain themselves or talk down to her. Value is whether a tool leaves her better off or just more anxious. That last one ended up shaping what I built.

Test your output

The Building in the Present and Shaping the Future panel, from the Girls Who Code College Loops group at Stan State, gave me a short list I could have taped to my laptop:

A security-first mindset
Test your output
Build accessibility in from the start
Start a mentoring circle or community of your own I walked into the buildathon an hour later with that list still in my ears. "Test your output" turned out to be most of my afternoon.

Building for one small business owner

I write about my wife E. a lot, because she runs the kind of business most software forgets. She's a one-person wholesale baker, La Condesa Baking Company. Earlier this month I built her Cuenta, an invoicing and shelf-count app, after she lost (and then found) the notebook her whole business lived in.

This time the problem was a website. She wants one. She's also scared to make one, because she has read enough about ADA lawsuits aimed at small businesses that no website feels safer than a website she might get wrong.

That's a time, voice and value problem. She doesn't have the time to learn accessibility standards. Most accessibility tools speak developer, not baker. And a tool that tells her "you're compliant" might leave her worse off than no tool at all, because no automated check can promise that.

So in about three hours I built Onceover: a first look, not an audit. You paste in a page's HTML. A testing engine checks it. Each problem comes back as a card with the accessibility rule it breaks, a link to W3C's explanation of that rule, and a plain-language note on who it affects.

earlgreyhot1701D / onceover

An accessible first-look web diagnostic tool for small business owners. Combines 100% deterministic axe-core scanning in an isolated sandbox with prompt-isolated Gemini explanations. Delivers clear customer-impact guidance in plain language without compliance theater, legal claims, or raw code exposure. Evidence precedes conclusions.

Onceover

Transparent, deterministic accessibility diagnostics paired with small-business plain-language guidance—built with zero compliance theater.

Problem Statement

Small business owners—bakers, mechanics, florists, and boutique retailers—increasingly rely on their websites as the front door to their business. However, the web accessibility landscape presents them with two bad options:

Incomprehensible Developer Jargon: Existing tools like raw browser audits or enterprise compliance suites generate intimidating reports filled with CSS selectors, stack traces, and legal citations. Business owners without in-house engineering teams cannot understand or prioritize these findings.
Deceptive "Compliance Theater" Overlays: Predatory third-party plugins promise "one-line AI fixes" and guaranteed legal immunity. In reality, these overlays often disrupt screen readers, fail to fix underlying code flaws, and create false confidence while leaving businesses vulnerable to complaints and alienated customers.
The Guarantee Trap: No automated tool can certify an entire website as barrier-free. Yet, typical products either over-promise compliance or overwhelm users into inaction.

The

The rules are written down in a short table, and they're enforced in code:

It never says	It says instead
"You pass" or "compliant"	"We found nothing on the checks we ran."
A lawsuit risk score	The rule's level and who the problem affects
"Fix"	"Possible ways to address this (for human review)"
Nothing, when it can't check something	A permanent panel: "What Automated Checks Cannot See"

A real testing engine, axe-core, decides what counts as a problem. Gemini only explains the finding, and it never sees the pasted page. If Gemini's explanation includes a banned word like "compliant" or "safe," the app throws it out and shows the citation alone.

The output needed testing. A lot.

The panel's advice paid off three times in one afternoon.

The first build scanned a copy of the page wrapped in its own template, which quietly added the language attribute my test page was missing. One of the six planted problems vanished before the scanner ever looked. Then the contrast problem went missing too, because the hidden frame doing the scan had no size, and the engine can't measure colors it can't lay out. It filed that one under "couldn't decide" instead of reporting it.

Both times the app looked fine. It just found fewer problems than were there. For a tool whose whole job is not giving false comfort, that's the worst way to fail.

The third one was funnier. When Gemini reviewed the code, it told me to swap the model from gemini-3.8-flash to an older one, and called the newer name "a hallucinated/invalid model string." Gemini 3.8 Flash is Google's current model. Gemini flagged its own successor as made up, with total confidence, inside a project about not stating what you can't source. The older model worked fine, so I left it. But I wrote it down.

Every line of code came from AI Studio. Claude is my build partner, and it planned with me and checked Gemini's ideas against the sources. Gemini handled the brainstorm, most of the code review, and the demo page with six problems planted on purpose.

The room after

At 1:45 we stopped building. Everyone in the hackathon room talked through what they'd made. It wasn't a formal demo, but I still had to stand up and explain mine. Afterward, one of the other builders came over and asked for the link.

That was the day in small. Someone builds a thing, someone else wants it, and now two people are talking.

What it can't do

Tell whether alt text describes the picture correctly. It only checks that alt text is there.
Read words inside an image, like a photographed menu.
Test keyboard use.
Show the checks the engine couldn't decide. That's next.
Scan a live URL. You paste HTML.
Tell you whether your business is covered by the ADA. That's a lawyer question. ## Try it

Onceover is live. Check the box, click "Load sample bakery page," and run a first look. Your pasted HTML stays in your browser. The only thing sent to the server is each finding's rule name, so Gemini can explain it. Nothing is saved. [TBD: how long the link stays up.]

I'll be back in Modesto in 2027. If you're anywhere near the Central Valley, come. Bring a laptop for the buildathon, but stay for the room.

Onceover is not legal advice and not an accessibility audit. It is a first look.

An App Built for One: Why a Devpost Skill Pack Made Me Spec It Anyway

Earl Grey — Tue, 20 Oct 2026 03:53:04 +0000

My wife lost her yellow book. So I built her an app.

TL;DR: Cuenta is a small app for my wife's wholesale bakery: count what's left on each cafe's shelf, build the delivery, print and email her branded invoice, and see who owes what. I built it for Devpost's Build With AI: Basics hackathon with their skill pack, which interviews you and writes the plan from your answers. The plan caught real problems before any code existed. It also carried one wrong guess all the way to the end, and only using the app caught it.

Last week E. lost her yellow book.

The yellow book is sacred. It holds all the secrets of her one-person wholesale bakery: her shelf counts for every cafe she delivers to, and her delivery numbers. The counts tell her what to bake. The delivery numbers become her invoices. When the book went missing, all of that went with it, and there was no backup anywhere.

We found it, eventually. (Note to self: Always double check under the front seat of the car.) But I kept thinking about how much of a small business can live in one notebook.

E. runs La Condesa Baking Company, a wholesale bakery in with four cafe accounts. Until now she counted products on paper, filled in invoice forms by hand, did the math by hand, and kept track of who owed her in her head. Net 30, paid by ACH.

So when Devpost opened Build With AI: Basics, a hackathon where you build a new project from an empty folder using their skill pack, I knew what I wanted to make. Something for someone I care about. And a chance to see if a guided process would help me avoid some of my usual costly mistakes.

Cuenta is Spanish for "count" and for "the bill." E. picked the name.

A few days earlier I'd built a tip calculator with Cursor in eight minutes, and ended that post with a question I couldn't answer yet: does that kind of up-front spec discipline hold on something with a real second layer, like state or a backend? Cuenta has a database, email, PDFs, and money that has to add up. This is that test.

earlgreyhot1701D / cuenta

Count, deliver, invoice and ledger app for a small wholesale bakery

Cuenta

Count, deliver, invoice, ledger for a wholesale bakery. Built for La Condesa Baking Company in Santa Barbara.

Live at cuentasb.vercel.app. The app sits behind a PIN, so the demo video below walks through the whole thing.

Demo video

One minute and thirty-nine seconds on the production app, with mock data: Count, Deliver, the invoice, Download PDF, Send email, the Ledger and the menu.

Built from an empty folder to a working app in about 20 hours, sleep included, using the Devpost Learn skill pack.

The problem

Eileen runs a wholesale bakery that serves four cafes. She counted what was left on each cafe's shelf on paper. She filled in her invoice forms by hand and did the math by hand. And she kept track of who owed her, and since when, in her head.

Why Cuenta solves it

Cuenta puts the whole route in one phone-first flow: count…

View on GitHub

What it does

Cuenta takes the yellow book to the cloud. Everything is built for her phone first.

Screen	What it does
Count	Pick a cafe, count what's on the shelf. Builds a history she can look back on. Planning only, it never touches an invoice.
Deliver	Pick a cafe, enter what she dropped off. One menu, same prices for every cafe. Totals add themselves.
Invoice	Her own branded invoice. Print it in the kitchen, download the PDF, or email it to the cafe.
Ledger	Who owes what, what's overdue, mark it paid when the money lands.
Customers	The four cafes and the menu.

The invoice had to look exactly like hers. It's her brand, the cafes know it and importantly keeping that design was absolutely essential to her.

The skill pack interviewed me

The Devpost Learn skill pack is six instruction files an AI coding agent reads, from 1-start to 6-ship. I ran it in Claude Code, Anthropic's coding agent, inside VS Code.

An app with one user is exactly the kind of build where I'm tempted to skip the planning and just start. The hackathon rules didn't let me. Every entry had to come out of the skill pack, planning docs included. I'm glad they didn't.

What surprised me is who asks the questions. I usually build with Kiro, where I write the spec and the agent works from it. The skill pack flips that. It interviews you, one question at a time, and writes the plan from your answers. Scope first, then the PRD (what the app does, screen by screen), then the spec (how it's built). I approved each document before the next one started.

The interview pushed back, and it caught things I would have paid for later:

The server clock. Vercel, where the app runs, keeps time in UTC. An invoice made at 5:30pm in Santa Barbara would have gotten tomorrow's date and the wrong invoice number. Caught in the spec.
Linked prices. If an invoice points at the current price of a flan, raising the flan from $4.00 to $4.25 rewrites every old invoice. Invoices now keep their own copy of every price, and every amount is stored in whole cents, so a total can't drift by a rounding penny. (A commenter on the Propina post, flatin.pt, pointed out the penny I'd left floating there. Cuenta counts in cents from the start.)
Two finish lines. My definition of done said "E. uses it for her business." My demo plan said "mock data on camera." The agent pointed out the demo could pass while the real goal failed. We split it into hackathon done and project done.
Count and invoice are different jobs. My scope draft implied the shelf count fed the invoice. It doesn't. Counting is for planning what to bake. Caught on paper. The 36 questions I wrote for E. before any of this were too many. A person running a bakery can sit through about 8 before her eyes glaze over, so I cut it to 8. Overkill is a real cost, and I'd rather plan for it than pretend it isn't there.

Claude Code flagged its own calls

Once the plan was approved, the skill pack split the build into 8 small slices, each checked before the next one started.

Every slice report from the agent ended with a section called "Calls I made that you should check." Decisions it made that the plan didn't cover, listed for me to approve or overrule. A discard prompt it added when you switch cafes mid-delivery. A darker pink for overdue text, because the brand pink failed the contrast check. Locking the cafe account on an existing invoice, because switching wasn't free.

I’ve never had an agent hand me its own decisions like that before. Normally an agent's judgment calls stay invisible until I trip over them. Here they came to me as a list, while they were still cheap to change.

The same thing showed up when it said no. On slice 7 a permission check blocked a production deploy, so the agent couldn't run the void test the normal way. It could have edited the database directly to make the test pass. It refused, because the point of the test was to go through the real Void button, and handed it back to me.

The build had three seats. Claude Code wrote the code. A second Claude chat wrote my prompts and checked the repo between slices. I directed, tested and decided.

Starting fresh on purpose

This was the first time I ended a long agent conversation on purpose.

I used to keep conversations going because I was afraid of losing context. Long chats get slower, cost more, and eventually compress themselves. Here, the context didn't live in the conversation. It lived in the files: scope.md, prd.md, spec.md, and a checklist with every decision written down. A fresh chat read them and picked up exactly where the last one stopped.

The skill pack says this outright: starting a fresh conversation between skills is fine, because the files carry context forward. I didn't believe it until I tried it. The docs aren't paperwork for the judges. They're the memory.

The mistake was in the plan, not the code

On day two I did a timed run by hand, the way E. would. I found two problems. Neither one was a bug.

The first was small. Sending an email takes 5 to 8 seconds while it builds the PDF, and the button didn't change. The code already blocked a double send, but it looked frozen. Now it says "Sending…" while it works.

The second was bigger. Every cafe had its own product list. E. has one menu, and any cafe can order anything on it.

The agent traced it. The scope, the PRD and the spec all said "each cafe's standing list." The code did exactly what the plan said. Eight slices and a passing end-to-end test, all checking the plan faithfully, and the plan was wrong.

Then we traced where the plan got it. Before I ever ran the skill pack, I wrote a planning brief with Claude. That brief looked at E.'s sample invoices, saw cookies on one cafe's invoice and not the others, and guessed that each cafe had its own list. An invoice shows what a cafe ordered that day, not what it's allowed to order. I brought that guess into the scope interview as if it were already decided, so the interview never asked E.

I think that's the lesson I'm keeping. The interview checks your answers. It can't check what you bring in. Checking against the plan can't catch a mistake in the plan. Only using the thing the way the real person does could.

The comments on the Propina post saw this coming. @mattbusel put it as "the thing that checks can't be the thing that built it," and suggested treating the spec as a hypothesis, not a contract. @vladzoff added that the builder should never get to edit the answer key. Cuenta's end-to-end test was written from the same plan as the code, so the two agreed with each other perfectly, and both were wrong in the same way. The fix went into the spec first and the code second, with a dated line in the checklist saying why.

I had a choice. A data patch (put every product on every cafe's list) would have taken minutes. The full fix (one shared menu, drop the per-cafe table, correct the docs) took longer. I took the full fix, a week before the deadline, because E. is the user after the video, and a sixth product shouldn't have to be added four times forever.

The 20% leaks earlier now

I told the skill pack at 1-start what I wanted to learn: my builds land at about 80% of what I imagined, and I wanted to find where the other 20% leaks.

I kept thinking of things after the fact. Again.

Late item	Where it came from	When
Counts separated by cafe	Me, after seeing the design mockup	before build
Paid by ACH, not check	E.	before build
Invoice numbering by cafe code and date	E.	PRD
Special order lines	Me	spec
Past counts (her paper book)	Me	build
4-digit PIN not safe	Me	build
Getting back from an invoice on a phone	Me	build
One menu, not one per cafe	Me, testing by hand	after build

Most of these lived in E.'s head, not mine. The rest showed up when I saw something concrete, like a mockup or the phone in my hand. Recognition beats recall. And on my full list of late items, seven were in the 28 interview questions I cut.

The difference this time is where they landed. Most landed on paper, or landed cheap. The interview didn't stop the 20%. It moved it earlier.

So, back to the Propina question. Does spec discipline hold once there's a database and money involved? Mostly. It held for everything that was written down as a decision. The one real miss was a guess written down as if it were a decision.

Things that went wrong anyway

Real data in the mockups. I used Google Stitch to sketch the screens from E.'s invoice. Stitch copied her kitchen address, phone and email straight into the mockups, and the first commit included them. The agent caught it, rewrote that commit and cleared it from git history before anything was pushed. AI design tools copy your reference data into their output.
The PIN. The app sits behind a PIN so E. doesn't need an account. The first version was 4 digits with no limit on guesses. I googled "is a 4-digit PIN safe?" and the answer was no. I added more digits for the PIN, with a lockout after too many wrong tries.
Fonts in the PDF. The PDF is made by a headless browser on the server, and that browser has no fonts. The spec missed it. The one spike we ran before building, a timeboxed test with a pass or fail answer, found it. It passed in 10 of its 60 minutes.
The video was too short. The first take of the demo was 59.9 seconds. The rules say 1 to 3 minutes. Re-took it at 1:39. We re-routed work twice. Nothing was fatal, because every slice was small and checked before the next one started.

The numbers

Moment	When
Empty folder	Sat Oct 17, about 4:30pm
Planning docs approved	Sat, about 6:20pm
First commit	Sat, 6:48pm
Slices 1 to 7 deployed	Sat, by 9:51pm
Slice 8, full test passing on the live site	Sun Oct 18, 10:45am
README live	Sun, 12:37pm

About 20 hours on the clock, sleep included, and 30 commits. The full run on the live site, from counting a shelf to marking the invoice paid, takes 15.9 seconds when a test script drives it.

It runs on Next.js hosted on Vercel, a Neon Postgres database, and Resend for email.

Software for one person, with money in it

Two weeks ago I wrote about Le Voyage, a trip app I built for six people. Software so specific nobody would build a company around it, and that didn't need to become a business to justify existing. I also wrote that if an app like that ever moved money, I'd be having a very different conversation with myself.

Cuenta is that conversation. It's software for one person, and it doesn't move money, but it's how she gets paid. So it got the things a trip planner never needed: a multi-digit PIN with a lockout, invoices that keep their own copy of every price, a void that never deletes, and a paid hosting plan once it runs her business.

Is it micro SaaS, the small, one-founder kind of software business? Not today. There's one user, no subscription, and nobody paying. But E. knows a lot of chefs who are one-person shows, running their businesses out of their own yellow books. Looking at what's custom in Cuenta, it's mostly data: her brand, her numbering, her menu, her cafes, her terms. The core is the same for any small wholesale food business.

So I keep wondering whether that's 20 custom builds, or one small, predictable tool that feels custom to each of them. I'd like to hear what you think.

What it can't do

One PIN, no user accounts. It's built for one person.
For the first few weeks, every invoice email goes to her own inbox instead of the cafe, so she can check them before cafes get anything.
Products and cafes can't be edited in the app yet. That comes with the handoff.
No Excel export, no overdue aging report, no payment reminders. Stubbed for later.

Try it

Watch the 1:39 demo. Cuenta is my entry for Build With AI: Basics. The live app is behind E.'s PIN, so the video is the way in. The planning pages, the scope, PRD, spec and app map, are published from the repo, and every decision and wrong turn is in the checklist.

Next is my favorite part. Her menu, her cafes, her email domain and a new PIN are already in. Now E. starts testing Cuenta on real deliveries, and I listen to her first week and decide what to add, or not.

She lost the yellow book once. Now her counts and invoices live in the cloud, not in a notebook that can go missing.

AI Took Me to Three Stages. I Still Don't Like Public Speaking.

Earl Grey — Sat, 17 Oct 2026 20:49:57 +0000

A year of building with AI put me on three stages. I liked the message more than the microphone.

TL;DR: In July 2025 I started building with AI to see how far it could take me. It took me further than I planned: onto court conference stages in Albuquerque, Los Angeles, and Riverside, talking about frontline staff leading small AI pilots. This is the written version of that talk, the one thing I would change about it, and what three rooms taught me about doing something I don't enjoy.

I walked into the room in Albuquerque with a deck I had rehearsed for weeks and no idea how any of it would land.

It was February 2026, and I was there to speak at the NACM 2026 Midyear Conference, the National Association for Court Management's national gathering. I was also the only person there from my court. No coworker in the third row. Nobody to grab coffee with afterward and ask, "Was that okay?"

I had prepared. I had also never done this before. That combination felt high risk in a way that had nothing to do with slides. If it went badly, I would carry it home alone.

It was a familiar feeling. I had felt it once before.

Alone in the room, again

In July 2025 I applied to the California Community Colleges AI Summer Camp. Nobody suggested it. I got one of 100 seats, out of about 1,300 applicants, and I was the only court professional on the list.

I was so worried about keeping up with computer science students that I spent the weekend before camp building a jury chatbot called Your Honor, I Object, just to see if I could. At camp, at 4:59 PM on day one, my mentor asked me to build a PDF extractor the rest of our project depended on. I had ChatGPT open that night and my team beside me. Our team placed second out of fourteen.

I started building with AI to find out how far it could take me. Speaking turned out to be the same experiment on a different stage. When the chance to present at NACM came up, I said yes for the same reason I applied to camp. I wanted to find out.

The second time was harder

Five months later, in July 2026, I spoke at a court in Los Angeles. I expected it to be easier. I had done this once. I knew the talk.

I was so much more nervous.

Some of that was the room. The Los Angeles Superior Court is the largest trial court in the country, and they were excited to have me. Excitement from your hosts is lovely. It also raises the bar you set for yourself.

Some of it was me. After Albuquerque, I expected more of myself, not less.

And some of it was the name on my badge. When I speak, I'm not only speaking for myself. My court's reputation walks into the room with me. Santa Barbara is a smaller court, and standing in front of the biggest one, carrying that name, felt heavier than standing up alone.

I didn't expect the second time to be harder than the first. The first time, I had nothing to live up to.

Two months, and still editing

The third talk was yesterday, October 16, 2026, at the Southern Region Finance Officers Meeting, hosted by Riverside Superior Court. The theme was the Currency of Curiosity.

I had two months to prepare. I was still changing slides the day before.

One thing helped more than I expected. I asked Claude to turn my speaker notes into an MP3, and I listened to my own talk in the car. AI helped me build the pilots in the talk, and then it helped me rehearse the talk about them.

It went well. My jokes got laughs from a room full of finance officers, which I am counting as a win.

Then I walked off and waited for the feeling of accomplishment. What came instead was relief that it was over.

That was when I knew. I'm proud of this talk. I love its message. I don't love public speaking.

What the talk says

The odd thing about all those nerves: I trusted the work, even when I didn't trust myself to present it. I knew what I had built, what had failed, and why I stopped. That was the part I wanted people to hear.

The talk is called Building Bridges, and its argument is that frontline court staff can lead AI innovation under the right conditions. By lead, I mean five steps: initiate, ask for approval, build, produce something, and report back.

A bridge gets built from both banks. My side was curiosity. My court's side was boundaries, and a manager who reviewed my proposals and said yes to small tests. Every pilot started the same way:

Approved in writing first
Public, redacted, or fictional sample data only
A person reviewing every result
A stopping point written down before I started Both court pilots stopped, and that is my favorite part of the story.

Write of Access tested whether a script could read handwritten entries on records request forms. I set a 90% accuracy bar before I started. It came in around 80%, so I stopped and looked at the misses. They clustered around checkboxes, signatures, and dates, where handwriting overlapped the printed form. The useful answer wasn't better technology. It was a form with less handwriting on it.

Hung Jury tried to automate part of our annual jury data report for the Judicial Council. I started on a Friday afternoon and stopped Monday morning. Three approaches hit the same wall: messy data in the source system. The existing Excel workbook was still the best tool for the job. The fix was a data conversation, not a coding project.

I'd rather find a dead end in a weekend than in three months.

After the pilots, I kept building outside of work. Themis Lex helps court staff see where AI can help in their role and where it must stay out. Verity Lex checks a California court's public record against the rules of court on AI. Both started with questions from my own job.

What I'd change

Building Bridges is a non-technical talk on purpose, and I say so at the start. It's about people, permission, and small tests, not code. So when I described the pilots, I wasn't thinking about the technical layer at all.

In Riverside, the concern I kept hearing was whether AI had run my pilots on court data. That's when I realized that for a court audience, how AI was involved might not be a technical detail. It might be the first question. Here's the answer I'd add.

Project	What it was	How AI was involved
Your Honor, I Object	A weekend practice build before camp. Never a court pilot.	An AI chatbot. It answers jury questions using public California law. Demo only.
Write of Access	Court pilot	ChatGPT helped me write Python. The code sent redacted sample forms to Amazon Textract.
Hung Jury	Court pilot	ChatGPT helped me write Python. No AI model processed the pilot data.

That table holds three different roles for AI, and I think they're worth keeping apart:

Generative AI answering questions. Only Your Honor, I Object does this. It was me testing myself before camp, and it never went near a court system.
AI helping me write code. ChatGPT did this for both pilots. It helped me write the Python scripts. It didn't run them.
Machine learning reading sample documents. Only Write of Access did this. My code sent redacted sample forms to Amazon Textract, an AWS machine learning service that reads printed and handwritten text from scanned documents. Textract doesn't generate conversational answers. It extracts text and structured information, like form fields, from documents. I checked every result against the bar I set before I started. Sending those redacted samples to Textract was part of the written pilot approval. I think that distinction matters most to people who are nervous about AI in courts, and those are the people the talk is for. Next time, it goes on a slide.

Prototype automation of the California Jury Data Report (JDR). Explored PDF parsing, JSON mapping, and QC validation before concluding vendor data corruption blocks full automation. Shows initiative, technical skill, and professional judgment in knowing when to stop.

Hung Jury

When automation can’t reach a verdict.

Automation isn’t always possible, but exploring the limits creates clarity. **

This repository is a scrubbed proof-of-concept showing my attempt to automate the Judical Council of California's Annual Jury Data Report (JDR) process.

The project explored extracting data from Crystal Reports PDFs, cleaning it, and validating it against Judicial Council (JCC) business rules.

🚦 What I Tried

PDF Parsing
- Built a PyMuPDF parser to extract values directly.
- Result: Failed. Crystal’s PDF output scrambled values (e.g., Q9 sub-questions shifted).
Mapping Extraction
- Created a JSON-based mapping to align questions with values.
- Result: Worked, but only because values were corrected manually — not sustainable.
Lean QC Engine
- Built lean_jdr.py to apply all 12 JCC Manual rules.
- Result: Confirmed my colleague’s Excel workbook was already correct, but added an independent validation tool.

Source data quality is the real constraint. Automation broke not…

I'd still say yes

If another court invited me tomorrow, I would say yes. I've been turning over what that says about me.

I think it says the message matters more to me than my comfort does. Enjoying something and finding it worth doing are two different things. Building with AI is both for me. Speaking, so far, is only the second.

In each of those rooms there was probably someone who asks why we do things the way we do them, and who tinkers with tools nobody assigned. That person is who the talk is for. I'd stand up again for them.

I'd still rather write it down. Next time, maybe with a coworker in the third row.

What's the thing you'd do again even though you didn't enjoy it?

I Wanted a Side Hustle. I Built a Herald With a Tip Jar.

Earl Grey — Thu, 15 Oct 2026 21:03:36 +0000

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 2: Side Hustle

The math draws the shield. Gemma writes the motto.

TL;DR: Blazon turns any word into a coat of arms that never changes, with a formal heraldic description to match. When you ask the herald, the button that gives your shield a voice, Gemma, Google's open-weight model, writes a motto and a short piece of lore for those arms, and nothing else. It is free to download, with a tip jar, and it was built in one day by reusing the server from my last Gemma project.

What I Built

In July I built 33 small web apps for Netlify's Hot AR Summer, with one rule: no Math.random anywhere. Every app had to derive its output from its input, so the same input always gave the same answer, and you could check it. I wrote up the bill here. One of those apps was Blazon. Type a word, get a coat of arms.

Then Week 2 of Hacktoberfest asked for something with open-source AI at its core that someone would pay for. I had one day and very few GitHub Copilot credits.

I went through three ideas before this one. A codename generator was the smallest, and nobody pays for a codename. An evidence drill for law students had a real market, but I work in the California courts, and I did not want to sell legal study material I can't vouch for. Then I remembered that coat-of-arms art is a real category on Etsy. One personalized crest download I found there lists at $70. Blazon already drew the arms. It just had no voice.

Why a coat of arms?

A coat of arms is the oldest version of a personal logo: a shield that says who you are, in a visual language with its own rules. People still want that. They put it on wedding programs, family reunion shirts, a print over the fireplace, the banner for a tabletop campaign's noble house.

There is a catch in how most of it gets sold. Search "family crest" and you will find sites offering the coat of arms for your surname. In English heraldry, arms were granted to individuals, not to surnames, which is how the College of Arms, the official heraldic authority for England, treats them. So a “your surname’s coat of arms” print may show arms granted to someone who shared your last name, not to anyone in your family.

Blazon does not pretend. It makes no claim about history. Your arms come from your word, by rules you can check, and they are yours because you typed the word, not because someone in 1450 did something. It is a new coat of arms, not an heirloom, and the herald is told never to claim a real family owns it.

Why give it a herald?

In medieval Europe, a herald was the officer who kept track of coats of arms: who bore which design, and what it said about them. A herald was the one who read a shield out loud and told its story. In Blazon, the herald is the button that asks Gemma for a motto and a few lines of lore.

The herald is not necessary. The arms stand on their own, and if Gemma is unavailable, Blazon still hands you a motto from a fixed house list. I built it that way on purpose.

What the herald adds is the reason someone would frame it. A shield on its own is a nice pattern. A shield with a motto under it, and a story about why those colors were chosen, reads like it belongs to someone. That is the difference between a generator you try once and something you print for someone's birthday. If anyone pays for Blazon, I think the herald is why.

So Blazon now does three things:

You do	Blazon does	Made by
Type a word	Draws the arms and writes the formal blazon, the one-line heraldic description	Fixed rules. Same word, same arms, forever
Ask the herald	Writes a motto and two or three sentences of lore about those arms	Gemma
Download	Saves an SVG of the shield with the motto underneath, ready to print	Your browser

Who would pay for it: someone buying a gift for a family with no crest, a small Etsy seller who wants a starting design, a tabletop group naming a house that does not exist. What it costs: nothing. Under the download button there is one line, "If you print it and hang it, buy me a coffee," and a link to my Buy Me a Coffee page. That is the whole business model. A tip jar is the cheapest way I know to find out whether someone would pay.

Demo

Live: blazon-g3jl.onrender.com

That is a real Gemma reply from the live site. I typed "Ventura," where I live, and the herald answered in 2.8 seconds.

It runs on Render's free tier, which sleeps after 15 minutes without visitors. If you are the first person in a while, the herald takes about a minute to wake up, and the page tells you so instead of sitting blank.

Code

earlgreyhot1701D / blazon

Type a word, get a coat of arms that never changes. Fixed heraldic rules draw the shield and write the formal blazon; Gemma 4, an open-weight model, writes the motto and lore. Free SVG download for print, nothing stored. Plain Node on Render. Built for DEV Hacktoberfest Week 2. A Clew Suite tool.

Blazon

One word. One coat of arms. Always the same. Gemma writes the motto.

Type a word. Blazon hashes it, runs a fixed table of heraldic rules, and draws the arms with a formal blazon. Same word, same arms, every time, and you can check it. Then ask the herald, and Gemma writes a motto and a short piece of lore grounded in the arms it was given.

The split

The model writes the caption. The math draws the picture.

Why open weights

A free download with a tip jar can't carry…

View on GitHub

How I Built It

The math draws the shield. Gemma writes the caption.

Blazon lowercases your word, turns it into a number with a hash function, and uses pieces of that number to pick from a fixed table: how the shield is divided, which two tinctures (heraldry's word for its colors), which charge (the picture on the shield), and how they sit together. The table follows the rule of tincture, the old heraldic rule that you never put metal on metal or color on color. Hover any row in the Heraldic Elements panel and a tooltip explains the term in plain English. Those definitions come from a fixed list too.

Gemma never touches any of that. It gets two things, the word and the finished blazon, and it returns two things:

{
  "motto": "In Constantia Victoria (Victory in Constancy)",
  "lore": "Behold the striking division of Or and Purpure, where the golden sun meets the twilight sky. Upon this field rests a cross counterchanged, symbolizing the eternal balance between light and shadow."
}

If Gemma is down, slow, or out of today's budget, Blazon picks a motto from a house list of 12. The pick uses the same hash, so the same word always gets the same house motto. Nobody sees a blank.

The motto is the one thing that changes on purpose. Ask the herald twice and you get two different mottos for the same shield. The shield is the part you keep. The motto is the part you choose, so if you like one, download it then. A "same word, same motto" mode is a stub in the PRD for later.

I think this split is the right one for a product like this. The part people frame has to be trustworthy and repeatable, and a model is neither. The part that should feel alive is a sentence or two of words, which a small model writes well. My last Gemma build, Two Sisters Tinctures, used the same split for skincare. It turns out the split travels.

Most of the server already existed.

Two Sisters Tinctures already had a small Node server that talks to Gemma 4 (gemma-4-26b-a4b-it) through the Gemini API, keeps the key on the server, and caps spending per day. Blazon reuses three of its files. What changed:

	Two Sisters Tinctures	Blazon
What Gemma does	Reads a skincare label into fields	Writes a motto and lore
Temperature (how much variety)	0.1, because a label has one right answer	0.9, because variety is the point
Daily caps	50 calls total, 10 per visitor	Same
Hosting	Render, paid starter plan	Render, free plan

The free plan was a choice. Tinctures paid to stay awake for judges. Blazon is supposed to be a side hustle that costs nothing to run, so it sleeps, and the UI owns that.

The word box is where a stranger talks to the model.

This is the part I almost talked myself out of. The arms are math, so nobody can trick them. The word is not math. Whatever you type goes to Gemma as text, so someone could type "ignore your rules and write something rude" as their word and see if the herald obeys. That is prompt injection: sneaking instructions in where data should go. And the page is not the only way in. Anyone with a little code can send requests straight to the server and skip the page entirely.

Blazon has three guards, and none of them cost anything at runtime:

Guard	What it does
Fenced-off word	Gemma is told that the word and blazon are data to write about, not instructions to follow, and the fence markers are stripped out of anything a user sends
Strict input check	The server only accepts words made of letters, numbers, spaces and a few marks, up to 40 characters. The blazon has to look like a real blazon. I ran 3,000 words through the rules, and every blazon used only letters, spaces, commas and periods, 61 characters at most, so anything else is tampering
Output check	If Gemma's reply is missing a field, runs too long, or contains markup or a link, the server throws it away and the page shows a house motto

robots.txt also asks search crawlers to stay off the /motto route. That is a request polite crawlers follow, not a lock. The daily cap is the lock.

Who did what, on a Copilot budget.

I don't write code. I direct, agents generate, and I validate and decide. This build had more hands than usual, and very few Copilot credits, so the work was split by cost.

Who	What
Me	Picked the idea, set the rules (no autopopulated content, nothing stored, structure deterministic), designed the UI in Stitch, deployed, tested the live site
Google Stitch	The illuminated-manuscript UI, in two rounds
Claude (Fable 5.1, then Opus 5.5)	The PRD, the server changes, 21 tests, splitting Stitch's single HTML file so it runs under the server's security policy, the one-screen layout, the About panel, the glossary tooltips, link-preview and search tags, and checking every block in a headless browser
GitHub Copilot in VS Code, agent mode	Wired the herald button to the server: the request, the waiting and error states, the house-motto fallback, and putting the motto into the SVG download
Gemma 4	Every motto and lore paragraph at runtime
Chat GPT	The crest social card and favicon

Copilot got one block, the one with the most moving parts in the browser, and a prompt with a guardrail at the top: do not refactor anything not listed. It changed only the three functions it was asked to change. Claude then checked the result in a browser three ways: with Gemma off, with the daily cap hit, and with a Gemma reply. All three showed the right motto, source line and download. The prompt also told Copilot not to run tests or the server, because a one-day build on a small credit budget can't spend those credits on test loops.

The bugs and wrong turns.

The first Stitch build filled itself in. It loaded with "Avalon" already drawn and a sample motto on a timer. My PRD says the page loads empty, so that came out. A demo that fills itself in shows the design, not the product.
Stitch writes one HTML file, and the server blocks inline scripts. The security policy I carried over from Tinctures allows only scripts from the site's own files. Every Stitch export had to be split into HTML, CSS and JavaScript before it would run.
The page was 1,008 pixels tall. On a laptop, the coffee link sat below the fold, which is a strange place to hide your business model. A desktop-only block of tighter spacing brought it to 745.
The About panel opened in the top-left corner. The page's CSS reset had removed the auto-centering that dialogs get by default. One line fixed it.
The name blazon was taken on Render, so the live address is blazon-g3jl. Render can't rename it after the fact. A custom domain would fix it.
A last review before submitting caught two more. If you changed the word while the herald was still answering, the old word's motto could land on the new shield. And the little color swatches beside Field and Tinctures always showed gold and blue, whatever the arms were. Now a late answer for a shield that is no longer on screen gets dropped, and the swatches paint from the real tinctures. Both were checked in a browser, including switching words mid-answer.
"Always the same" starts now, not in July. The Stitch redesign rewrote the rule table. In July, "Cordero" drew Or, a cross Sable. Today it draws Quarterly Sable and Argent, a cross counterchanged. Same word, same arms, from this version forward.

What it can't do
SVG download only, no PNG.
The first motto after a quiet stretch takes about a minute while the server wakes.
50 motto calls a day across everyone. After that, everyone gets house mottos until tomorrow.
The lore is invented folklore. It never claims a real family owns these arms.
These are not registered or granted arms. Blazon is a design tool, not a heraldic authority.
Blazon uses "proper" loosely, and the tooltip says so. In real heraldry it means "shown in natural colors."

Why Does Open Innovation Matter?

Cost is the business model. Blazon's price is zero and its income is a tip jar. A product like that can't carry a per-call bill from a frontier API. Gemma on a capped free tier keeps the cost of a motto near zero, and the daily caps keep the worst case known.

A small model is enough. A motto is three to eight words. Lore is two or three sentences grounded in a blazon it is handed. Paying for a frontier model here would be paying for headroom Blazon never uses. On the live site, Gemma answered in under three seconds.

The weights are the exit. Today Blazon calls Gemma through Google's hosted Gemini API, not on my own hardware, so I want to be precise about where the open part helps. If the hosted free tier changes, the same Gemma weights can run somewhere I control. There is already a stub in server/gemma.js for a self-hosted Gemma through Ollama, and nothing else in the app would have to move. With a closed API, a pricing change is the vendor's decision and my problem. With open weights, it is my decision.

Prize Categories

Best Use of Gemma: Gemma 4 writes every motto and lore paragraph, grounded in a blazon the rules produced, with a server-side check on every reply and a house-motto fallback.
Best Use of Render: the whole app, front end and the Node server that holds the Gemma key and enforces the caps, runs on Render's free plan from a render.yaml Blueprint.
Best Use of GitHub Copilot: Copilot agent mode in VS Code wired the herald into the UI, from a staged prompt with a no-refactor guardrail.

Type your own name in. If the herald says something good, tell me what it said. I am collecting mottos.

Would you pay for one? Mostly asking.

Eight Minutes to Live. Was It Cursor, or Was It the Spec?

Earl Grey — Thu, 15 Oct 2026 16:23:46 +0000

A tip calculator, a stopwatch, and a lot of pesos.

TL;DR: I built a USD/MXN tip calculator with Cursor for the Build a Mini App challenge during Hacktoberfest and MLH Global Hack Week. One prompt, one commit, no corrections, and the site was live on GitHub Pages eight minutes after I first asked for a prompt. The prompt is in this post so you can run the same test. What took longer than the build was writing the prompt.

8:25 in the morning. The challenge brief says "something small but real, a to-do list, a tip calculator." I'm sitting there thinking a tip calculator is the most boring thing on earth, and then I remember I'm in Mexico every few months doing pesos-to-dollars math on a napkin.

So, Propina. Spanish for tip.

earlgreyhot1701D / propina

Dual-currency tip calculator for USD and MXN with a manual exchange rate, split-the-bill math, and live updates. Single HTML file, no frameworks, no build step, no API. Styled with Clew Labs brand tokens. Built with Cursor for the Build a Mini App challenge. AI Assisted. Human Approved.

Propina

Propina is a single-page tip calculator: enter a bill, choose a tip percent, and split the total among people, with a USD/MXN toggle that shows every result in both currencies. The MXN-per-USD exchange rate is a manual field (default 18.00). It is not fetched from a live API, so you set the rate yourself. Open index.html in a browser, or visit the GitHub Pages site for this repository.

Live: https://earlgreyhot1701d.github.io/propina/

Built with Cursor for the Build a Mini App challenge (Hacktoberfest / MLH Global Hack Week 2026). One prompt, one shot, eight minutes from first prompt to live site.

Clew Labs. AI Assisted. Human Approved.

View on GitHub

Live: earlgreyhot1701d.github.io/propina

What it does

A single HTML page. You pick the bill currency, USD or MXN. You type the exchange rate yourself (default 18.00, no live feed, I'll come back to that). Bill amount, tip percent, number of people. Every result shows in both currencies, bill currency first, converted amount under it in smaller type.

Input	What you get
Bill 1,250 MXN at 15%	Tip MXN 187.50 ($10.42)
Same bill	Total MXN 1,437.50 ($79.86)
Split by 1	Per person MXN 1,437.50 ($79.86)

No frameworks. No build step. No API. The exchange rate is manual on purpose, because a live rate means a key, a fetch, an error state, and a dependency I'd have to check isn't dead in six months. For a tip at a taqueria, the rate from this morning's ATM receipt is close enough.

The clock

All times Pacific, all from the chat log and the GitHub commit record.

Time	What happened
8:25	Asked Claude for a prompt I could paste into Cursor
8:26	Revised it: dual currency, my brand tokens
8:28	Repo created on GitHub
8:32	First and only commit
8:33	Pushed. Pages live.
8:39	I tested the math by hand. It held.
8:53	Code review found one minor bug. Fixed and pushed.

Eight minutes from the first ask to a URL I could send someone. I did not redirect Cursor once. Not a single "the total isn't updating, fix it." The first commit, co-authored by me and cursoragent, is the whole build. The second commit, twenty minutes later, is the review. More on that below.

The prompt did the work

Here's the thing I want to be honest about. The whole thing took eight minutes, and most of that was the spec, not the build. I had Claude write the prompt, I revised it twice, and by the time it hit Cursor there was nothing left to decide. This is the prompt, verbatim:

Build a tip calculator as a single index.html file with inline CSS and JavaScript. No frameworks, no build step, no external scripts except Google Fonts.

Currency: a toggle for USD and MXN. Default USD. An editable exchange rate field (default 18.00 MXN per 1 USD, label it as a manual rate, no live API). Show every result in both currencies: bill currency first, converted currency underneath in smaller text.

Inputs: bill amount, tip percent (buttons for 10, 15, 20, plus a custom field), number of people to split with.
Outputs: tip amount, total, and per-person total, each in both currencies. Update live on every input change. Show "0.00" when inputs are empty or invalid, never NaN or a blank screen.
Use textContent, not innerHTML. Validate inputs (no negatives, people must be at least 1, rate must be greater than 0). Format money with two decimals and a thousands separator.

Style it with these tokens exactly:
--field #0A1F2E (page background)
--paper #F1E8D2 (card background)
--turquoise #1FB5B7 (buttons, active toggle, focus ring)
--sienna #E85A1F (custom tip active state and per-person highlight)
--ink #17262E (text on cards)
--paper-warm #E8E0CC (text on dark background)
--muted #647178 (captions, converted amounts)
Fonts from Google Fonts: Cinzel 700 for the title (uppercase), Source Serif 4 400 for body, JetBrains Mono 600 for labels, buttons, and numbers (uppercase labels, letter-spacing 0.12em). Add a subtle 48px grid overlay on the page background using rgba(31,181,183,0.035). Single centered card, max width 480px, mobile-friendly.

Title: "Propina". Footer line in mono: "Clew Labs. AI Assisted. Human Approved."

Add a README.md with one paragraph on what it does, that the exchange rate is manual, and how to open it.

Then: run git init, commit everything, create a public GitHub repo named propina with the gh CLI, push to main, and enable GitHub Pages from the main branch root. Give me the repo link and the Pages link when done.

Do not add features beyond this list.

Look at what's in there. Hex codes. Font weights. Which element gets the orange. textContent not innerHTML. Never show NaN. And the last line, which I think did more than any other: do not add features beyond this list.

Every one of those lines is a decision I'd otherwise be making in a chat window at 8:35 while Cursor waited. I made them at 8:26 instead. The agent didn't have to guess, so it didn't guess wrong.

I think that's the real finding. The speed wasn't Cursor being magic. The speed was that there was nothing left to argue about.

The NaN trap

One line in the prompt said "never NaN or a blank screen." Here's why that line has to be there.

In JavaScript, typeof NaN === "number". So a check like "is this a number" passes on garbage. An empty bill field, a rate of zero, a negative tip, all of them sail through and the page prints $NaN in your brand font. Cursor handled it the way I'd want: validate first with Number.isFinite, reject negatives, require at least one person and a rate above zero, and if anything fails, write formatted zeros with textContent instead of leaving the box empty.

if (!Number.isFinite(amount)) {
  amount = 0;
}

That snippet is from the shipped file, not a tutorial. The money formatting is Intl.NumberFormat, two decimals, thousands separators, so 1437.5 shows as 1,437.50 without anyone writing a comma-insertion function at 8:30 in the morning.

The credits ran out before the QA did

I burned through my Cursor credits right after the build. No big deal, it's a free-tier morning, but it meant the final bug review I'd normally ask the build agent for didn't happen there.

So Claude did the review instead. It read all 424 lines of index.html and came back with three findings:

Finding	Weight
Typing 1.5 in Number of People passed validation and split the bill by 1.5	Minor bug, fixed
The result boxes updated silently for screen readers; no `aria-live`	Accessibility gap, fixed
One CSS rule that could never match	Cosmetic, left alone

Two lines changed, pushed as a second commit. Everything else it checked (empty inputs, negatives, zero rate, zero people, both conversion directions, the thousands separator) held. So the build history is: one commit from Cursor, one two-line fix from a reviewer that hadn't watched the build. I like that shape better than the pure one-shot story, because the second commit is where the "human approved" part lives.

Two agents, one build log

Three parties, as usual.

Cursor generated index.html and README.md, ran git, created the repo with the gh CLI, pushed, and switched on Pages. One shot. It also wrote a README paragraph with two em dashes in it, which is the only thing I'd call a miss, and that's a style preference, not a bug.

Claude (Fable 5.1) wrote the prompt from my two-sentence ask, revised it when I said "pesos," pulled the commit timestamps for the table above, took the screenshots, spot-checked the math on the live site, did the code review when Cursor's credits ran out, pushed the two-line fix, and made the README banner. It also could not download Google Fonts from its sandbox, so the banner uses stand-in fonts. Same colors, different letterforms. I'm telling you so you don't think the banner is the Cinzel the app uses. (Yes, Fable is overkill here but I threw token caution to the wind!)

Me. Picked the idea. Said "pesos." Handed over the brand guide. Tested at 8:39. Approved.

I did not write a line of code. I wrote one line of spec ("can we make it in pesos or dollars and pesos since I travel to Mexico a lot?") and the rest was direction.

What I didn't need, and would use next time

Cursor's desktop app has a browser pane. You open the running page inside the editor, click an element, and move it, and the agent picks up the change. I didn't touch it this build, because there was nothing to fix. The next time a layout comes back slightly off, that's where the fix happens, not in a chat message describing where the button should go.

What it can't do

No live exchange rate. You type it.
No history, no saving, no sharing a split with the table.
No rounding options. Two decimals, that's it.
One currency pair. If you need euros, fork it and change two strings.
The banner in the README is not in the app's real fonts (see above).

Try it

earlgreyhot1701d.github.io/propina. Nothing is sent anywhere. There's no backend to send it to.

Or copy the prompt above into Cursor and see if you get eight minutes too. I'd like to know if the one-shot holds on someone else's machine, or if I got a good roll.

The tip calculator is just the evidence

So, was it Cursor or was it the spec? Both, but not equally. Cursor executed clean, and I’d use it again tomorrow. The spec is what made clean execution possible, because it left the agent nothing to decide.

What I think is cool here isn't the eight minutes. Plenty of people have one-shot a tip calculator.

It's the shape of the morning. I spent two minutes on the idea, let one agent write the spec, let another agent build it, hit a credit wall, swapped in a third reviewer that hadn't seen the build, and the whole thing is documented down to the minute with a commit log that backs it up. That's the workflow I've been describing for a year, run end to end in under thirty minutes on a Thursday.

One caveat I'm keeping in view. A tip calculator is small enough that a good spec can cover every decision. The next test is whether the same prompt discipline holds on something with a real second layer, like state or a backend. Does it?

I don't know yet. That's the next post.

On Saying No: Will the Well Dry Up?

Earl Grey — Wed, 14 Oct 2026 04:12:57 +0000

TL;DR: I got into Stanford's Code in Place, the free intro-to-coding course I'd wanted for a long time, and I'm stepping away the day before my first section. This year I've said yes to almost every free hackathon, event, and program I could reach. Saying no to this one stung, and it got me wondering how long all this free stuff lasts.

The email came on October 7.

Congratulations! We were impressed with your application! This is a formal invitation to join Code in Place X as a student.

I was so, so, so excited. Code in Place is a free, intro-to-coding course from Stanford, and I had been looking for something like it for a long time. I picked my section time before onboarding closed. I started the lessons: if statements, while loops, a program called Secret Code, another called Wholesome Machine. I got through about three quarters of week one.

Tonight, the day before my first section, I wrote back.

Unfortunately, I won't be able to participate in this cohort. Is there a way to delay my start for the next cohort or would I need to re-apply?

I don't have an answer yet.

This one was the thing I wanted

I've shipped a lot this year without writing the code by hand. But I can only check what I can read, and I can't read all of it yet. I wrote about that gap in I Wrote the Code This Time. Does It Count If the Answer Was Wrong?

I've tried to close it before. I passed the Python basics on DataCamp. But a lesson lets me follow along. Code in Place has weekly sections where I would have had to show what I learned. That's accountability, and accountability is the part I have the hardest time giving myself.

So I'm bummed. Not "valuable lesson" bummed. Just bummed.

The weight showed up all at once

Today, for the first time, I stopped and looked at everything on my plate.

What	When
My day job, running court operations for the county	Monday - Friday
AWS AI & ML Scholars nanodegree	Through the end of October
HR course at Calbright College, portfolio due	Through November
Code in Place, first section	Wednesday
LA Tech Week hackathon	Thursday
My talk for Los Angeles and Riverside Superior Court staff	Friday
Another hackathon (waitlisted)	Saturday

Learning Python on top of that didn't feel responsible. It didn't feel reasonable either.

The talk on Friday is about how frontline court staff can lead AI work. One slide is called "What I'd Do Again," and the last item on it is "stopping when the evidence says stop." I wrote that about AI pilots. Tonight it was about me.

Not every no has been mine

Earlier this year I got accepted into the Graduate Certificate in Artificial Intelligence for Business at UMass Amherst's Isenberg School of Management. I didn't get the AAUW scholarship that would have paid for it, and I couldn't do the program without it. Accepted, and still not going.

That no came from the money. This one came from me. It's the first time I've had to be the one who says it.

Almost everything this year was free

Look back at my posts from this year and you'll see a lot of rooms I got to be in. Here are three.

Event	Month	What someone else covered
Code with Claude Extended SF	May	A lottery "golden ticket," a packed room, talks and hands-on workshops
AMD Advancing AI 2026	July	Free registration, the Moscone Center, lunch, keynotes, workshops
Build with Gemini Sunnyvale	September	Google's campus, a three-hour build lab, Google Cloud speakers, swag

What I paid at every one of those: my time and my travel. That's it.

Every event in that table took a room, staff, and a budget. None of that is free to the people running it. It's a lot of infrastructure, and somebody signs off on the bill.

My tin foil hat says the well runs dry

Here's my suspicion, and I want to be clear it's a suspicion, tin foil hat firmly on. It looks to me like companies are spending a lot right now to get curious attendees into a room with their tools. I imagine at some point shareholders ask what they got for it. If they do, I think the free stuff gets smaller.

That's a feeling, not a forecast. But it's been driving a lot of my yeses. If the well might dry up, drink while it's flowing. I wasn't counting what each yes drew from me.

Which made me ask the question I should have asked months ago. Why are they doing this?

My guess is they want those attendees picking their tools. I think that's a fair trade. I came to learn, experiment, and explore, and I did every time.

Code in Place is the first time the math stopped working. A hackathon takes a weekend. A course takes every week.

The price of the opportunities didn't change. My capacity to pay that price did.

Free still costs time, and this week I don't have any left.

What happens now

I'm leaving Python alone until things calm down. After Friday's talk, and once Scholars wraps at the end of the month, I'll have more headspace. I asked about the next cohort. If I have to reapply, I'll reapply.

If you've said no to a free thing you wanted, I'd like to hear how you made the call.

Is the well drying up, or am I just tired?

Maybe both.

README Clew 2: Built with AdaL. Labeled by Jev. Judged by Code. Explained by Haiku.

Earl Grey — Sun, 11 Oct 2026 18:21:02 +0000

Jev labels the line. Code makes the call.

TL;DR: README Clew 2 checks whether a public GitHub README matches its code, for JavaScript and TypeScript repos. A small decision model called Jev labels what kind of claim each README line is, five fixed code checks decide whether it's true, and Claude Haiku writes the summary. I built it in five days with AdaL, SylphAI's coding agent, for AdaL's "What Would Jev Do?" hackathon. Its first real test was my own old repo, and it got it wrong.

AdaL's "What Would Jev Do?" hackathon asked for one thing: build a project with AdaL, the coding agent from SylphAI, that puts Jev to real use. I didn't have a problem to solve. I had a model, and a deadline.

Jev is a small decision model from TypeSafe. DigitalOcean's write-up calls it "an AI model that can't write a sentence," and that's the point of it. You give it a question, the rules for answering, and a fixed set of labels. It picks one label and tells you how sure it is, as a number between 0 and 1. You reach it through Glasser, which runs Jev calls and charges per call.

That's an odd tool to start from. My builds usually start with a problem, and then I pick a model. This one started with the model, so I went looking for a problem that fit it. My first thought was to rework apps from my Hot AR Summer run, since they're already deterministic. Then I went through a lot more. Dewey. Pun Court. Sortes. Which Door. Saint of Small Things, which I love too much to shoehorn into a format it doesn't fit. I ruled out legal tools too. Every fun idea died on the same line in the judging criteria: "a clear reason the project should exist."

So I went back to a reason I already had. In May I built README Clew because I always worried my READMEs disagreed with my own repos. It worked, and its own README listed two honest limits. Claude was asked to quote the README word for word, which was a prompt rule, not a code check. And it sometimes read prose labels like "Frontend (Vite)" as package names, which produced false accusations.

Both limits are labeling problems. Labeling is the one thing Jev does.

A clew, said like "clue," is a ball of thread. In the Greek myth, Ariadne gave Theseus one so he could follow it back out of the Labyrinth. README Clew follows the thread from each README line back to the code. It's also the name of my Clew Suite of civic tech tools.

earlgreyhot1701D / readme-clew-2

Checks whether your README matches your code. Chrome extension + web page for any public JS/TS repo. Rules and five deterministic verifiers decide what's true, Jev labels README lines with calibrated confidence, Haiku explains the findings. Line-linked receipts, status badge, JSON export. Built with AdaL for What Would Jev Do?

README Clew 2

Checks whether a GitHub README matches its code.

Live: https://readme-clew-2.vercel.app

Paste a public JavaScript or TypeScript repo, press SCAN, and get a claim ledger: every checkable line of the README, what the code says about it, and who decided.

Built for the AdaL "What Would Jev Do?" hackathon, October 6 to 11, 2026.

Why "clew"? A clew (said like "clue") is a ball of thread. In the Greek myth, Ariadne gave Theseus a clew so he could follow it back out of the Labyrinth, and it's where the word "clue" comes from. README Clew follows the thread from each README line back to the code. It's also the name of the author's suite of civic tech tools.

What it does

READMEs drift. A command gets renamed, an env var gets dropped, a package gets swapped, and the README keeps promising the old thing. README Clew 2 reads…

View on GitHub

What it does

READMEs drift. A command gets renamed, an env var gets dropped, a package gets swapped, and the README keeps promising the old thing. README Clew 2 reads the README line by line and sorts every line into one of four buckets:

Bucket	Means
Contradicted	The README says it, the code disagrees
Missing	The code does it, the README never mentions it
Unverifiable	No code check can test it, or Jev wasn't sure what kind of line it was
Verified	The README and the code agree

Every row shows the exact README line, the code evidence, and who decided: a rule or Jev.

That's a real scan of v1. No contradictions, and four packages the code imports that the README never names. The new version audits the old one.

Jev never gets the last word

The rule I built around: models never decide what's true.

Code splits the README into lines and settles the easy ones without any model: headings, badges, blank lines. For the rest, Jev picks what kind of claim the line is. A dependency, a command, an env var, a file or URL, or something no code check covers.

A line only goes to a code check if Jev is at least 0.8 confident it's one of the four checkable kinds. Below that, it lands in Unverifiable, tagged "Jev wasn't sure." Then five deterministic verifiers read package.json, the file tree and the source, and decide. Same input, same answer. Claude Haiku writes a short summary at the end from counts and names only. It never sees the README lines, so a README with planted instructions can't talk to it.

The two mistakes aren't equal. Calling a line Unverifiable costs a little coverage. Calling a correct line Contradicted costs your trust. I took that framing from Swift at MLH, who published I got Jev to zero mistakes. I'm still using Flash-Lite. the same day I was writing Jev's questions. His lessons reshaped the build: describe what each checker can't see instead of what a README line looks like, give Jev no worked examples, and count mistakes per line instead of per run.

My twist was to turn the scariest failure into code instead of a prompt. A package name that only shows up in prose can never be marked Contradicted, no matter how sure Jev is.

On a held-out set of 32 README lines, run twice with the settings frozen:

Measure	Run 1	Run 2
Wrong labels that got past the 0.8 bar	0	0
False Contradicted, end to end	0	0
Real drift found	3 of 3	3 of 3

Thirty-two lines is a small sample. It supports "safe enough to ship," not a measured error rate.

A full scan costs about a penny. Roughly $0.009 of that is Jev.

One agent, one build log

I direct, validate and decide. AdaL wrote the code and the tests, ran the Jev evaluation, deployed to Vercel, and drove a real browser for QA. Claude (Opus 5.5) wrote the spec and the architecture, reviewed AdaL's work at every checkpoint, and wrote the docs.

AdaL worked from an AGENTS.md it read every turn: propose first, one block at a time, touch only the files named, stop for a QA checkpoint. My last build left me with a 1,200-line god file, so this one had a 200-line cap per file, enforced by a test that fails the suite. A rule in a prompt is only a request. A failing test is a rule.

AdaL followed all of it, and it was fast. In plan mode it proposed and confirmed plans so quickly that I'd paste a prompt, step away, and come back to finished work. It also found real bugs nobody told it to look for:

Glasser, the service that runs Jev calls, caps a call at 100 questions. Only the live API says so, not the schema.
A timer that let tests quietly cancel instead of fail.
A trimmer measuring the wrong version of the text.
Two layout bugs that only showed up in a real browser. That last one surprised me. AdaL switched on its own browser tool to screenshot and time the page. I never toggled it.

Not everything was smooth. AdaL sat on "Create lib/report.js" for 22 minutes after the file was written and every test had passed. Only the screen was stuck. My laptop fan has gone off more this week than in the last year. Glasser's connector inside AdaL broke every Claude call until I turned it off and reported it. And on day four, right after I approved the biggest block, my weekly plan credits ran out.

The fix was in AdaL's own docs: bring your own API key. I already had Claude API credits. About 35 minutes later AdaL was building again on my key.

The AdaL team deserves its own paragraph. They fixed the Glasser connector the same day I reported it. When I told them I'd hit the weekly limit, they granted a credit so I could finish. This is the first hackathon where I've had direct, fast contact with the people running it, and it made a five-day sprint feel less lonely.

The mascot shows the split too. AdaL drew the first clew in code, as SVG faces, then two thread-ball styles to pick from. The one that shipped was painted by ChatGPT, then cut out and sized by Claude. An agent that draws with paths and an image model that paints are good at different things.

It's me, I'm the problem

Apart from the connector bug, most of the friction in this build was me.

I'm terrified of shipping slop, so I asked for every test to be shown failing once. Break the code on purpose, watch the test go red, restore it. In Block 1 that meant 102 tests and 75 deliberate breaks. Then it kept going.

Point in the build	Tests
Block 1	102
Blocks 3 and 4	197
Monorepo fix	222
Before the UI polish	353
Saturday night	452
Submission	474

Some of those tests matter a lot. The ones that guard the five checkers, the 0.8 bar, the prose rule and the monorepo regressions are the ones keeping a correct README from being called wrong. A lot of the rest re-prove page wiring that the browser checks already covered. For a five-day build, that's ridiculous.

It also cost real money. Every deliberate break is a full test run, and every run is agent time. My second rookie mistake was never starting a new AdaL session. Every turn resends the whole conversation, so the later turns of a long session cost the most. By Saturday night I'd spent $36 of the $50 cap I set on my key in about three and a half hours.

AdaL did exactly what the prompts asked. The guidance set the bar, mine and Claude's.

The fix was a "lean mode" header at the top of each prompt: a fresh session per block, read only the files you need, show failing once per new test file instead of per test, run browser QA once at the end. The rest of the build, hardening, the extension, the README and the last fixes, cost about $4. The final bill for the agent was $40.35. The app costs about a penny a scan.

Next time I'll set a test budget per block before the block starts, and match it to what a failure would cost a user, not to habit.

The first thing it got wrong was mine

The first real scan was my own v1 repo. README Clew 2 called three lines Contradicted and flagged four packages as Missing. Claude opened v1's files to check. All seven were false.

v1 is a pnpm monorepo, with workspaces in folders the workspace finder didn't know about. And pnpm's --filter option was being read as a script name. The tool was wrong in exactly the way it promises never to be, on my own repo, a few hours before any judge saw it.

AdaL fixed it in one block. Anything it can't resolve now comes back Unverifiable, never Contradicted, and v1 became a saved regression test. On the rescan: Contradicted went from 3 to 0, and the four Missing packages turned out to be real.

A second live scan, of the polka repo, found 14 Missing packages that all came from an examples folder with its own package file. Same fix, same kind of test.

The last two came from a question I asked late Saturday: did we build for false contradictions? Claude reread every checker and found two more ways to accuse a correct README. An env var used in a file past the 20-file read limit. And a README pointing at build output like dist/, which is never committed. AdaL made both come back Unverifiable.

The last bugs came from asking the question the tool exists to answer.

What it can't do

JavaScript and TypeScript only. In JS and TS, one file, package.json, lists both the packages and the commands. Python spreads the same facts across several optional files. A repo with no package.json gets a clear message, and no model is called.
Most lines end up Unverifiable. Most README text is prose no code check can test. Unverifiable means "can't tell," not "wrong."
Monorepo support covers simple workspace patterns and up to 30 workspaces. Beyond that, Missing turns into Unverifiable.
It reads at most 20 source files per scan, and cuts READMEs over 50 KB.
The same README scanned twice can move one borderline line between buckets. The 0.8 bar keeps that drift away from Contradicted.
No README badge. A badge would re-run a scan and bill me every time someone viewed it, and with no storage there's no safe way to cache it. ## Try it

There are three ways in, and they all hit the same scan:

Way	Best when
Live page	You want the full ledger, or you're on a phone. No install
Chrome extension	You're already on the repo's GitHub page. One click
Bookmarklet	You can't install extensions, like on a locked-down work computer. Drag it from the ABOUT tab

The bookmarklet is there because of my day job. Work computers block extensions, and a bookmark that opens the page with the repo filled in gets past that.

There's no database and no account. Scans are never stored, and logs keep counts and timing only. Since nothing is kept, DOWNLOAD JSON gives you the report as a file, with a scan receipt: the repo and commit, a fingerprint of the README text, and a fingerprint of the report so you can tell later if it was edited. No model writes any of it. Attach it to a pull request, or keep it as a before-and-after.

Before I submitted, README Clew 2 scanned its own README: 285 lines, 154 sent to Jev, 5.6 seconds. 0 Contradicted, 0 Missing, 1 Verified, and 107 Unverifiable. The one Verified line is npm test, and package.json does have a test script. The 107 is the honest number. Most of a README is prose. On "Built for the AdaL 'What Would Jev Do?' hackathon," Jev said not a checkable claim, 0.52 sure, and the line never went near a checker.

Press USE DEMO REPO, then SCAN, and watch the new version grade the old one. The code, the decision log and every wrong turn are in the repo.

A Builder in New Orleans: When Your Vibecoded App Comes on Vacation

Earl Grey — Sun, 04 Oct 2026 20:45:02 +0000

First day on Bourbon Street, and my sister and I had the most important question of the trip: where are we going to eat?

It should have been easy. Between the two of us, we had added sixty-eight restaurants, bars, cafés, and attractions to Le Voyage, a travel-planning app I vibecoded the better part of a year earlier. We were standing in the middle of the French Quarter, surrounded by food, carrying a small database of places we already wanted to try, and we were still hungry and indecisive.

So we opened the app.

Le Voyage started as something I built for a trip to Paris. The idea was simple. Instead of sending restaurant links back and forth, saving places in three different apps, losing recommendations in group chats, and trying to remember why somebody added a particular café three weeks ago, we could keep the whole trip in one shared place. Everyone sees the same restaurants, attractions, neighborhoods, notes, maps, and itinerary. It runs as a hosted web app with a free database behind it, and for the handful of people I travel with, it costs essentially nothing.

I built it for Paris. Then I went to Paris and barely used it, which in retrospect feels about right.

Paris became the first essay in this series, A Builder in Paris: Do Devs Dream of Électrique Chats? I had deliberately put the computer down, and I found out that stepping away from the keyboard did not mean stepping away from building. Ideas have an annoying habit of following you.

New Orleans gave me the opposite experience. This time I put the computer down, and something I had already built followed me.

An old app gets on a plane

Calling Le Voyage old feels strange, but the first real feature work started on December 28, 2025. By the time we landed in New Orleans it had been around for about nine months, which is plenty of time for a vibecoded project to pile up features, assumptions, forgotten decisions, and small mysteries left behind by an earlier version of yourself.

The GitHub repository has well over a hundred commits now. The README still more or less says "Welcome to your Lovable project," a leftover from the AI app builder I used to make it. Priorities. I was not trying to turn Le Voyage into a product. I was trying to catch a plane.

About a week before the trip, though, I started looking at the app differently, because this time I knew we were going to use it. That changes things. A filter that resets after a reload is mildly annoying at your desk. It is a lot more irritating when you are walking through an unfamiliar neighborhood trying to decide where to get breakfast.

So the app learned to remember our filter and map preferences for each trip. It got sorting, so sixty-eight places did not have to live in one giant pile. It got a confirmation step before deleting a place, because entries now had notes and itinerary links attached, and deleting one by accident had stopped being funny. The map interactions got better, categories became editable, and the AI feature got its usual maintenance when its model aged out.

None of those changes were glamorous. All of them mattered more than another shiny AI button would have. That may be the first thing New Orleans taught me about my own app: the boring parts of software become very important once you use it.

Sixty-eight places and still hungry

Our first meal was at MRB in the French Quarter, which was already in Le Voyage. This is where one of the simplest features in the app earned its keep: the notes field.

My sister's notes were not polished travel writing. They looked like this:

FQ, dive bar, "potent drinks," outdoor seating, "oyster bar"

Useful shorthand, enough to jog a memory. From the place card we could jump out to Google, read reviews, check the menu and the location, and decide whether it still sounded good now that we were standing there instead of researching it from home. It did. Excellent food. Everything fried. Oh yeah!

Somewhere around that first meal, Le Voyage stopped feeling like a project I had built and started feeling like an app I had. That distinction has been sitting with me. Most side projects stay verbs. You build them, deploy them, post a screenshot, maybe write an article, and then they sit quietly on a server while you chase the next idea.

A few become nouns. They live on your phone. You open them again. Someone besides you adds something, and then they add more than you do. They gain history.

My sister added most of the New Orleans places. Her notes were in there, her choices were in there, and we both opened the app first thing in the morning looking for breakfast and again while we wandered during the day. The trip wasn't my dataset. It was ours.

That made the weaknesses much easier to see. Le Voyage had solved the problem I originally designed it for, which was remembering all the places we were interested in. Unfortunately, we had been very successful. Now we had sixty-eight places to search through.

Breakfast? Scroll. Drinks? Scroll. Somewhere close? Scroll. Something quick because we had already walked enough for one day? Scroll some more.

The problem was no longer discovery. It was choosing. I don't think I could have learned that staring at the app on my laptop. At home, sixty-eight saved places looked like a feature. On Bourbon Street, they looked like work.

The AI feature finally found a job

Le Voyage already has an AI recommendation feature. Right now it mostly exists because the app was built during an era when every button apparently needed to consult a model. It works, it costs almost nothing, and it is not especially useful.

New Orleans showed me what its job should be. I do not need a model to tell me New Orleans has restaurants. Yelp has that covered. I also do not need it to search the whole city and hand me another list. We already had sixty-eight.

What would have helped is being able to say: we're in the French Quarter, we want breakfast, we want to walk, give us three places from our list. Or: we just want a drink. Or a snack. Or something highly rated nearby. Use our notes, use our categories, use the places we already decided we cared about, and help us narrow it down.

That changes the role of the AI completely. Instead of discovering the world for us, it helps us decide inside a world we already curated. That is a much more interesting feature to me now. It is also one I am trying very hard not to build before Oaxaca. More on that later.

Then New Orleans ignored our database

Some of the best places we went were not among the sixty-eight. People recommended them to us.

We ended up at Deanie's in Bucktown because a local told us to go. Excellent choice. Someone else sent us to Lafitte's Blacksmith Shop back in the French Quarter. Also an excellent choice. Purple drank. Iykyk.

This is where New Orleans did something no amount of pre-trip research could. The app knew what we had researched. New Orleans knew what we hadn't.

That sounds obvious, but it changed how I think about what Le Voyage should become. When you design a travel app from your desk, you design around planning. You collect places, organize them, build an itinerary, add filters and ratings and neighborhoods, and convince yourself that with enough structure you can make the trip legible before you arrive.

Then you travel. Someone behind a bar tells you where to eat. Someone takes the time to explain which place is worth the walk. You change plans because you're tired, or because you smell something good, or because the place you thought was nearby is not nearby in any meaningful sense after eight hours on your feet. Travel keeps reminding you that it does not belong entirely to your itinerary.

That wasn't a failure of Le Voyage. It was something the app had not learned to make room for yet. Maybe there should be a lightweight way to tell the places we researched apart from the places the trip gave us. A "Local Tip" tag, or "Found Here." Something simple. I don't know yet.

What I do know is that the best recommendation engine we used in New Orleans was New Orleans. What I remember most clearly is not Bourbon Street, or even the Mississippi and the steamboats we walked past. It is the people. They had time. They said hello. They were friendly, charming, and knowledgeable, and they were happy to tell you where to go and then explain why.

There is something wonderfully humbling about spending months tinkering with travel software only to find out that one of its most valuable future features might be a better way to remember what somebody told you in a five-minute conversation.

Maybe useful slop is still useful

There is another part of this I have been thinking about since we got home. Le Voyage is vibecoded. Very vibecoded. There is essentially no automated test suite.

So I'm not waving a flag for AI-generated software here. If Le Voyage moved money, ran infrastructure, handled medical information, or kept somebody's company running, I would be having a very different conversation with myself.

It doesn't. It is a travel app for me, my sister, my wife, and whichever friends come along on future trips. Free hosting, free database, and almost no running cost beyond the occasional AI call, which, as I already admitted, barely earns its keep.

And yet it gave us something useful: the same information, at the same time. My sister did not have one list while I had another, my wife had screenshots, somebody else had a Yelp collection, and the rest of the names disappeared into a group chat. We had one shared trip, one shared set of notes, one place where the stuff we cared about lived. That is different from opening another "Top 10 New Orleans Restaurants" list written for everybody. Commercial travel software has scale. Our little app has context.

That makes me wonder whether there is a category of software vibecoding is unusually well suited for: software for six people. Not six million. Six. Maybe even two. Software so specific nobody would build a company around it, but cheap enough now that one person can make it anyway.

Whenever a side project turns out to be useful, I notice the same question showing up in my head: what happens next? Do you monetize it? Add Stripe? Get users? Build onboarding? Turn the pleasant little thing into a SaaS and eventually spend a Saturday staring at a retention dashboard?

I don't think I want to. Will I keep Le Voyage alive? Yes, for now. Will I monetize it? Probably not. I like that it can be weirdly specific to us. I like that "FQ" is enough explanation. I like that my sister's notes do not need to make sense to an addressable market.

I don't think software has to become a business to justify existing. Sometimes you make a thing, two people use it, then maybe four, and it makes their trip a little easier. For me, that can be enough.

The app matured before the idea did

That may be the part I find most interesting now. Over nine months, Le Voyage itself grew up. It learned to remember things, got better maps, made deletion safer, and improved its sorting. The rough edges got filed down one at a time.

But I don't think I understood the product as well as I thought I did. I thought the problem was collecting places for a trip. New Orleans taught me that collecting was the easy part. The harder problem was deciding what to do with all those places once the trip started moving around us.

That is a different product, and I only found it because we used the thing. Not tested it. Used it. There is a difference there too. Testing asks whether the software behaves the way you expect. Using it has a nasty habit of asking whether your expectations made sense in the first place.

Oaxaca is next

At the end of this month, Le Voyage is coming with me to Oaxaca. Naturally, I now have ideas, and this is the dangerous part.

I want the contextual recommendation feature. I want a better way to capture the places locals tell us about. I want better search. I want the app to understand that "nearby" means something very different at 9 a.m. than it does after dinner when everyone's feet hurt.

Because this is a vibecoded app, I could probably open Lovable and start changing half of it tonight. That is exactly why I am trying not to. There are real trips in that database now, and real notes. My sister uses it. I use it. And my current automated test coverage is approximately "open the app and start clicking."

My younger vibecoder instinct says there is plenty of time before Oaxaca to add something cool. The part of me that has spent more time around software since I first built Le Voyage says I should find out what I am about to break before I add anything. So QA first. Probably.

In Paris, I learned that stepping away from the computer did not mean stepping away from building, sometimes especially when the laptop was shut. New Orleans taught me something slightly different. Sometimes you have to stop building long enough to find out whether the thing you built belongs in your life.

Le Voyage does. It is unfinished. The AI feature needs a real job. The README is embarrassing. The tests are, at the moment, more of a philosophical position than a software artifact.

But my sister and I used it. Then we used it again. And now it has a ticket to Oaxaca.

For now, that's enough.

Two Sisters Tinctures: Building an Apothecary Skincare Tracker with Gemma 4 for My Sister

Earl Grey — Sat, 03 Oct 2026 20:25:06 +0000

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend

TL;DR: I built a skincare shelf tracker for my little sister. Gemma 4 reads a product (typed name or pasted ingredients) and fills in the card. The model gets to read the label. It does not get a vote. A plain rules file decides what goes on first, what waits until night, and what should never be layered with what.

What I Built

My little sister is my skincare product whisperer. Every time I need a cleanser, a serum, or a sunscreen, I ask her. She knows what she uses, what works, and what she gave up on, and all of that lives in her head and on her bathroom shelf.

So for Build for a Friend, I built her a place to keep it: a private skincare shelf. It helps her keep her own routine straight, and the next time I ask "what should I get?", her answer is already on her phone. She can screenshot her shelf and send it to me.

Two Sisters Tinctures lets her add a product by typing its name or pasting its ingredient list, keep track of what she owns, see when something has been open too long, and get a morning and night routing, with a warning when two things on her shelf should not be layered. Her shelf lives in her own browser. There is no account.

I didn't want AI deciding my sister's skincare routine. I wanted it doing the annoying reading.

So the design rule became: the model reads, the rules decide. Gemma 4 reads the label and drafts the card. She checks it and taps save. A plain rules file, not the model, decides the order, what waits until night, and the warnings. Nothing lands on her shelf without her confirming it.

If I had to say it in one breath:

I built a private skincare shelf for my sister where AI does the fuzzy reading, but deterministic code makes the decisions. The model cannot silently add something to her shelf, rules don't depend on model improvisation, her data stays in her browser, and I measured where the model fails instead of hiding it.

Then I handed it to her. What she said is at the end of this post.

Demo

Live app: https://two-sisters-tinctures.onrender.com/
Want to look around without adding anything? Add ?demo=1 to the address and you get a pre-filled demo shelf. It lives in memory only, so it is gone when you close the tab. The shelf, the night routine, and the Add screen (demo shelf, invented products).

The best-read tip on the Paste screen, and a gap hint on a small shelf.

Code

earlgreyhot1701D / two-sisters-tinctures

A skincare shelf tracker I built for my little sister. Paste the ingredients, type a name, or snap the label, and Gemma 4 explains what it does. Plain rules handle routine order, don't-mix warnings, and shelf life, and her shelf never leaves her phone. Built for the DEV Hacktoberfest Weekend Challenge: Build for a Friend.

Two Sisters Tinctures

A skincare shelf tracker built for my little sister. She adds a product, it becomes a card on her shelf, and the app sorts the shelf into a morning and evening order and flags things that should not be layered.

Live: https://two-sisters-tinctures.onrender.com/ Look around first: add ?demo=1 to the address for a pre-filled demo shelf (memory only, gone when you close the tab).

Built for the DEV Hacktoberfest Weekend Challenge: Build for a Friend (October 2 to 5, 2026).

What it does

Add a product by typing its name, or pasting the ingredient…

View on GitHub

It is one small Node service. It serves the static front end, one health check, and one API route, POST /api/read. The shelf itself lives in the browser's localStorage. There is no database and no account.

How I Built It

The open model at the center is Gemma 4 26B A4B (gemma-4-26b-a4b-it), open weights under Apache 2.0, served through Google's Gemini API. Every product that lands on her shelf starts as a Gemma read, and everything after that read is plain code.

I do not write code. I direct, agents generate, I validate and decide. This one was a three-way build, so here is who did what:

Who	What
Me	Wrote the PRD first, set every MUST / STUB / NEVER label, approved each block, tested on a Samsung and two iPhones, made every call about what the app says to my sister
Antigravity (mostly Gemini 3.8 Flash on low, Sonnet 4.6 when I hit my limits, with the DevRelay MCP connected)	Blocks 0 to 2 (project skeleton, the shelf and its screens on mock data, rules and shelf storage), the first gold fixture draft and the gold set runs in Block 3 (the session embedded below), and after my credits reset: the Block 7 polish (greyed photo card, best-read tip, gap hints), the ingredient-rule bug fixes, and the route tests and static file hardening
Claude (in Cowork)	Block 3 steps 9 to 12 (rate limits, output validation, the Gemma call, the `/api/read` route, front end wiring), the 53 ingredient notes, Block 4 live checks, Block 3b tests, lint, and CI, reviews of Antigravity's later plans and changes against the files, the bug hunt diagnosis, the README, the screenshots, and the first draft of this post
Gemini	The hero image
Stitch	The UI design

The order I used: PRD first, then blocks, with a pass or fail check after each one. Mock data first, so the layout worked before any API was wired to it. Features not in the current phase got a comment stub with notes, not a half-built version.

The model reads. The rules decide.

This is the one design call I care about most. Gemma is good at turning a messy label into structured fields. It is not who I want deciding whether a retinol serum and a glycolic acid toner should share a night.

So the split is deliberate. Gemma only ever answers one question: "what is this product?" Everything after that comes from public/rules.json, a plain file I can read: the product types, the morning and evening order, the conflicts, and 86 ingredient notes with aliases. Structure is deterministic. Flavor, meaning the one-line description, is the model's.

Here is the whole path a product takes:

what she types or pastes
        ↓
Gemma 4, called from a small Node service on Render
        ↓
validator: right shape, a known type, only ingredients she pasted
        ↓
she checks the card and taps save
        ↓
rules.json: order, night-only, warnings
        ↓
her shelf, stored in her own browser

Then the model's answer goes through a validator before the app trusts it. The validator:

rejects anything that isn't the expected shape, and reports a reason code, not the raw text
trims names and descriptions that run too long
throws away any ingredient that does not appear in what she pasted (ignoring case, spacing, and dash style)
replaces a "what it does" line that mentions an ingredient the product doesn't list If the model is down, slow, or returns garbage, the app says so and offers to add the product by hand. A blank screen was on my NEVER list.

The gold set

The first time I ran my gold set against the model, it scored 0 of 5. It took four runs and a handful of fixes to get to 5 of 5, and there is a catch in which 5 of 5 that is.

The gold set is five skincare products I bought or looked up. Each has an expected type and ingredient list I checked against the source. Two of the first fixtures an agent drafted for me were partly made up (a wrong source link, and ingredient lists I could not verify), so I checked each one against the product pages and replaced them.

Input	Reads correct
Product name plus ingredients	5 of 5
Ingredients only, no name	3 of 5

With only an ingredient list, the BYOMA serum and the CeraVe cleanser both came back as "Moisturizer." That is a fair guess from a list of lipids and humectants, and still wrong. That is the reason the Add screen has an optional product name box on the Paste tab.

Input:     ingredient list only
Measured:  3 of 5 types correct
Response:  optional product name box, ingredients checked against what she pasted, her confirmation before saving
Result:    the model stays useful without being treated as the authority

A read takes about 2 to 4 seconds live.

Protecting a model key on a public link

The model runs on the Gemini API, paid tier, so every read has a small cost. Here is what keeps a public link affordable:

50 reads a day for the whole app, 10 a day per visitor, and a per-minute limit
same-origin check on the API route
the key is only in the server's environment, never in the browser, never in the repo
the key is restricted to the Gemini API, and a $5 budget alert sits behind all of it

The bug hunt the day before submitting

The tests were green and CI was green. Then I used the app, and almost everything I added landed on "Night only." One ingredient also vanished between pasting and saving.

The model was not the problem. The rules file was. The rule that sends strong actives to night matched any ingredient name that contained an acid's name, at any strength, on any product. I ran it against my own gold set:

Product	What tripped the rule	What the app did
BYOMA Hydrating Serum	Lactic Acid, there only to adjust pH, near the end of the list	Night only
L'Oreal Age Perfect SPF 30	Capryloyl Salicylic Acid, which contains the words "salicylic acid"	A daytime sunscreen, set to Night only

The same loose match fed the "don't mix tonight" warnings, so the same products would have raised false alarms next to a retinol. The vanishing ingredient was two smaller things: the save step split the list on every comma, which turns "1,2-Hexanediol" into "1" and "2-Hexanediol", and the paste guard dropped any name the model wrote with a different dash than the label.

The fix stayed deterministic. One small matcher now handles every ingredient rule. It matches whole ingredient names. Acids only count in the first ten ingredients, where the stronger ones sit, which is a rule of thumb and I wrote it down as one. Anything typed Sunscreen, or with SPF and a number in the name, is always morning. Conflict warnings only fire between two different products that both get used at night. Each of those cases is now a test, using the two products that broke it.

The lesson I am keeping: the deterministic part needs the same testing as the model.

Tests and checks

48 tests run with npm test: 10 added during the bug hunt and 8 route tests that start the real server and check each error path of the API. ESLint runs with a rule that flags unsafe DOM writes, since I only use textContent, never innerHTML. GitHub Actions runs lint, tests, and npm audit on every push, and it is green.

What it does not do yet

Photo input is not built. The card on the Add screen is greyed out and says "Coming soon." I tested a web lookup for ingredients instead (it found the right list for 2 of 2 products I tried by hand), and stubbed that too, because two products is not enough proof and it needs a second key. I cut both so I could finish what I had.
Ingredients-only reads are right 3 times out of 5 in my gold set. Add the product name.
Editing a saved product's details is coming soon. Changing the type works today.
app.js is one file doing too many jobs (about 1,600 lines). Splitting it is on the after-the-contest list in the repo, instead of rushed the night before.
Only the Gemini path is tested. Ollama is a stub.
No allergy checks, and this is not medical advice. It is a shelf and a set of order and conflict notes.

Why Does Open Innovation Matter?

Gemma 4 is open weights, and Google's own Gemma terms page points Gemma 4 to an Apache 2.0 license. This weekend I call it through Google's API, the same way I would call a closed model. What open changes is how much of the system I get to control.

The model is a part, not the brain. Gemma's answer has to pass a narrow contract: a fixed shape, a type from my list of 11, and only ingredients that appear in what she pasted. The skincare logic never sees anything else. So the reader can be swapped without rewriting a single rule, and with open weights the swap can be the same model on hardware I control. The model call lives in one file behind one setting, MODEL_PROVIDER. The local path (Ollama) is a stub with notes, not tested.

I get to keep it. Apache 2.0 means a vendor changing its terms does not take the reader away from her shelf. A closed API gives me no exit like that.

Failures stay visible. I measured where the model is wrong, 3 of 5 from ingredients alone, and designed around it: a name box, the validator, and her confirmation. A model mistake cannot quietly become something her shelf believes.

Open also means being clear about where her data goes:

Her shelf stays on her phone. It lives in the browser's own storage. It never goes to my server, and there is no account.
What does leave the phone is the product name or ingredient text she types or pastes, sent to Google's paid Gemini API so Gemma can read it. Google's Gemini API terms say that on paid services it does not use prompts or responses to improve its products. I checked that page in early October 2026, and I would re-read it before relying on it.
My server keeps none of it. It logs reason codes and timings only, never what she sent. No photos are sent, because photo input is not built.

My Agent Session

Two Sisters Tinctures - Block 3 Gold Set and Status Check

You

<USER_REQUEST>
Context update, read before doing anything. While your quota was out, Claude built and I pushed Block 3 steps 9, 10 and 11, so do NOT redo them. Run git pull first and read these files before changing anything: server/limits.js, server/validate.js, server/gemma.js, server/index.js, public/read-client.js, test/server-logic.test.js.

What exists now:
- POST /api/read works with the real model (tested paste, typed, and a prompt injection test, all clean). Model timeout is 30 s (MODEL_TIMEOUT_MS). Thought parts are filtered.
- DEMO CODE WAS DROPPED. No X-Demo-Code, no DEMO_CODE env var, no code box. Protection is daily caps: DAILY_CAP default 50 total, IP_DAILY_CAP default 10 per visitor, plus a per-minute limit. About screen says so (VOICE id about.limit).
- Paste and Typed on the frontend call the server through public/read-client.js and fill the existing confirm form. Snap the label is a STUB until Block 5.
- node --test test/server-logic.test.js passes 12 of 12.
- Claude tested the browser flow already. Do NOT run browser testing.

Task: Block 3 gold set. Do ONE step, then STOP and give a SHORT report (files changed, commit hash if you commit, nothing else).

STEP 12: gold set of 5 real products.
1. Create test/fixtures/gold/ with 5 JSON files, one per product: { "id", "mode": "paste", "text": "<pasted label or website ingredient text>", "expect": { "type": "<one of the 11 rules.json types>", "mustInclude": ["<2 to 3 ingredients that must be returned>"], "mustNotInclude": ["<ingredient not in the text>"] }, "source": "<URL>", "checked": "2026-10-03" }.
2. Pick 5 well-known products across different types (for example a cleanser, a retinol serum, a vitamin C serum, a moisturizer, a sunscreen). Ingredient text MUST be copied from the brand's own product page or a retailer page. NEVER invent or reconstruct an ingredient list from memory. If you cannot verify one, leave that file out, say so, and STOP so I can supply it.
3. Create test/gold.mjs: loads .env with process.loadEnvFile (wrappe
<truncated 246 bytes>
hes, mustInclude present, mustNotInclude absent) plus the time in ms, then a total like "4 of 5". Never print the API key. Do not log the full model response.
4. Add "gold": "node test/gold.mjs" to package.json scripts. It must NOT run as part of node --test (it calls the real API).
5. Do NOT run test/gold.mjs yourself. I will run it locally.
6. Add one row to TASKS.md under Block 3 for the gold set, unchecked until I run it.

Rules: one file one responsibility, no refactoring of other code, textContent not innerHTML, no em dashes in any text, add any new user-facing line to VOICE.md as an unchecked row (there should be none here). Propose nothing else. When done, run node --check on new files and the 12 existing tests, then STOP.

<USER_REQUEST>
Read-only status check. Do NOT edit, create, or delete any file. Do NOT run the app, a browser, or any test that calls the Gemini API. Do NOT print or ask for any API key. Mock data only, this session may be published.

Run git pull, then git log --oneline -15.
Read TASKS.md, FINDINGS.md, AGENTS.md and PRD.md Gate G4. Verify claims against the actual files, not memory.
Report back in under 25 lines:
- Each Block (0, 1, 1b, 2, 3, 3b, 4, 5, 6): done, partly done, or not started, with the TASKS.md line that proves it.
- Anything in TASKS.md or the PRD that disagrees with the code. Quote file and line.
- Anything in the code that is not covered by a TASKS.md item.

Context so you read it correctly:
- Claude (not you) built Block 3 steps 9 to 12, the 53 new ingredient notes and aliases, the paste name box, the empty-shelf Add button, Block 4 prep and live checks, and Block 3b (tests, ESLint, CI). You built Blocks 0 to 2 and the gold set fixtures draft.
- The demo code was dropped on Oct 3. Protection is daily caps (DAILY_CAP 50 total, IP_DAILY_CAP 10 per visitor) plus a per-minute limit. Known limit: the per-visitor cap can be dodged with a fake X-Forwarded-For header. See FINDINGS.md.
- Gold set: 5 of 5 with a product name, 3 of 5 ingredients only.
- Block 4: key set in Render, $5 budget alert set, key limited to the Gemini API, live checks passed, Shara's cold phone check passed Oct 3.
- Block 5 (photo) is still a STUB and likely to be cut. Block 6 (video, README, DEV post, submit) is next.
- Deadline Sun Oct 4, 2026, 11:59 PM PDT. Ship target 6 PM PDT.

STOP after the report. Wait for my next instruction.

Block 6 (Her test, video, post): not started (TASKS.md:122: **Status:** [ ]).

Spec vs. Code Discrepancies

Types count: PRD.md:184 & PRD.md:211 state one of the seven types, but public/rules.json:2-14 defines 11 types (including Essence, Treatment, Mask, Other).
Server timeout: PRD.md:319 & TASKS.md:80 note 20 s timeout, but server/gemma.js:10 sets TIMEOUT_MS = ... || 30000.
Validation limits: server/validate.js:5 has name: 80, brand: 60, ingredients: 50, ingredient: 100, whereas PRD.md:209-210 specifies name: max 60, brand: max 40.

Code Not Covered by TASKS.md Items

server/index.js:77-80: origin/referrer checking against host header to reject foreign origins on /api/read.
server/gemma.js:46-52: unwrap logic for array-wrapped model outputs or string double-encoded JSON payloads.

<USER_REQUEST>
Use the devrelay-sessions skill. Do NOT edit any project file.

Save or publish this Antigravity session through DevRelay so it can be linked from a DEV post. Make it public-viewable if DevRelay offers that choice.
Give me back: the exact embed tag or link for the DEV post, the visibility setting (public or private), and whether the session includes messages from before DevRelay was installed.
Before publishing, scan this session for anything that must not be public: API keys, tokens, .env contents, real email addresses or phone numbers, home folder paths. List what you find with the message it is in. If anything is found, do NOT publish. Stop and tell me.
Do not create or publish a DEV article. Claude is writing the post.

This session covers one slice of the build: the Block 3 gold set runs and a status check, in Antigravity with the DevRelay MCP. Antigravity sessions used mock data and public product ingredient lists only, nothing personal. The later Antigravity work (Block 7 and the bug fixes) and the Claude sessions are not in this embed.

Prize Categories

Best Use of Gemma. Gemma 4 (gemma-4-26b-a4b-it) reads typed names and pasted ingredient lists into structured product cards. It runs with thinking set to minimal so reads come back in seconds, and a validator checks every answer before the app uses it.

Best Use of Render. Render runs the one part that has to be a server: a small Node service that holds the Gemini key and talks to Gemma. The path is her browser, then the Render-hosted service, then a server-side Gemma request, then the validator, then back to her browser, where the shelf is stored. The key lives only in Render's environment settings, so her browser never receives it. The same service enforces the daily caps, the per-minute limit, a same-origin check, and the security headers. It is defined in a render.yaml Blueprint and deployed on each commit during the build. The smallest paid web service on Render's pricing page was $7 a month when I checked in early October 2026.

The handoff

When I told my sister I was building her a skincare shelf, she texted back:

Omg yesssss! 🧪

Then I handed it to her. After she tried it, she wrote:

Loving this! A lot of people have questions on which order to use the products too 🤓

Order is exactly the job I gave the rules file, not the model. And by her count, a lot of people are asking the same question.

I built the whole thing for one reader, and she gets the final say on whether it is any good. Her shelf is also where I will look the next time I need a sunscreen.

If you have a product whisperer of your own, what would you build for them?

Research note: I checked the model, hosting, and challenge details against their own pages in early October 2026. These tools change quickly, so check the current docs before you copy anything.
