Challenge Prompt
Build for a Friend
Build something with open-source AI at its core.

That can mean running an open-weight model, building on an open-source agent harness or framework, running inference locally, or all three. Whatever you pick, the open pieces should be what makes your project work.

In your post, tell us why open innovation matters for what you built. Does it run on a laptop with no internet? Keep someone's data off a server they don't control? Let you fine-tune, swap models, or change how your agent behaves? Cost nothing to run? Tell us where your open-based approach worked better than a closed one.

This Weekend's Theme: Build for a Friend
Ship something that solves a real problem for a friend or someone you love.

Pick one real person and build something for them. It doesn't have to be big. It has to matter to them. A few ideas to get you going:

A meal planner that knows your roommate's allergies

A patient practice partner for a friend learning a new language

A tool that turns your grandpa's voice memos into a family recipe book

Bonus points if you actually hand it over and tell us what they said.

Submission Template
Show your work. We'd love to see how you built it. Save your agent session with DevRelay and embed it in your post, or link to it. It's optional, but it helps the judges understand your process.

[thinking] Download running in background. Meanwhile, let me think about what else needs building while waiting:

docs/research/ — measurement notes (to fill after run).
Improve the product: is there anything missing that makes it matter for the friend? Consider:

[thinking] llama-server has a global --json-schema flag — that constrains ALL generations server-wide. And /v1/chat/completions also accepts response_format. Let me get the full help listing to check flags I use in _cli: -m, -p, --sys, -n, --temp, -ngl, -c, --no-echo, --std.

The grep only matched `--thr …

[thinking] So llama-cli supports -p, -sys (not --sys? it says "for system message, use -sys"), -m, -ngl, -c, --temp, -s seed. Need to check -sys exact flag and whether --std and --no-echo exist. Let me grep for "sys" and "echo" and "std".

Also important: llama-cli in non-interactive mode with -p prints ge …

[thinking] llama-cli supports -j/--json-schema SCHEMA and -o/--output FNAME — writing generated text to a file! That's the cleanest way to get clean output in CLI mode: --output-file writes only the generated content, avoiding loader chatter parsing.

Wait — does -o write only the generated text? In llama-cli, --output/ …

Agent

[thinking] Now rewrite _cli to use -sys, -j (json schema), -o output file, --no-log-prefix, --color off, and drop --no-echo/--std. Keep the prompt-only fallback if no schema.

Also _server should keep response_format. Let me read the top part of engine.py to see _server and the Engine class.

[thinking] cli mode: 12.4s total (model load + generate) and the model didn't return JSON — meaning either -j schema wasn't applied or output file empty/different.

[thinking] No GPU backend lines logged at that verbosity. 2 tok/s with 24 threads suggests something pathological — grammar-constrained decoding with a big GBNF can be slow, but 2 tok/s is way too slow for a 4B model (normally 20-40 tok/s on CPU with 24 threads).

[thinking] Interesting — the harness seems to be rewriting "By" → "1s"? It looks like some substitution is happening in my command text (maybe a typo-correction layer). Let me avoid the word "By": use Get-Process | where ... or use --%? Alternative: use tasklist /v and sort in bash.

Agent

[thinking] tasklist /fo accepts order: STATUS, IMAGES, MEMORY, VSIZE, NTHEARDS, CPUTIME, TIME, MODCOUNT, PID, SESSION, PRIMARYIP, DFLT, DFLTNG, DFLTGUI, DFLTCLR, DFLTDBG. So "MEMORY".

tasklist //FO MEMORY //V — /V verbose adds window title. Let me get name + mem columns.

[thinking] Hmm. Maybe the // escaping turns into "/MEMORY"? Let me use powershell to run tasklist: powershell -NoProfile -Command "tasklist /fo memory /nh" — but "fo"/"memory" fine.

Actually maybe the issue: git-bash converts //FO to /FO fine, but tasklist wants /FO memory lowercase? It said value not allowed... Perhaps …

Agent

[thinking] Weird. Maybe this tasklist is a different variant. Let me stop chasing this; the key fact I need is available RAM (376 MB) — that's enough to explain the slowness and to justify the decision. I don't need the process list; I can ask the user whether their Strata server is running (they said it maxes RAM/GPU).

[thinking] Confirmed: -j grammar in llama-cli fails with Gemma's chat template (<start_of_turn> token accepted by the grammar stack then empty stack). This is a llama.cpp bug in this build (b11379) for Gemma + GBNF in cli mode. Server mode works.

[thinking] cli mode works without the grammar (model emits fenced JSON — parse_json_loose must strip ```json fences). Output file includes the prompt echo ("User: ... Assistant:") which I must strip.

[thinking] stdout includes the ASCII banner and prompt echo. So -o file is cleaner (prompt echo + generation, no banner). Best approach: use -o file and strip the echoed prompt by removing the leading substring equal to the prompt we sent.

Robust: read file, then find the last index of the user text we sent; take everythin …

[thinking] _cli works and returns fenced JSON. So parse_json_loose should handle it... unless doctor's failure came from a different path. Wait — the RAW has fences; parse_json_loose finds first { and last } → parses fine. So why did doctor fail?

Maybe doctor calls Engine.complete with a schema that has `additionalProper …

Agent

[thinking] The doctor prompt is 'Say the word "ok".' with schema {"ok": boolean}. In cli mode, the model probably responded with prose like ok (no JSON braces) because the schema instruction is appended... Let me reproduce exactly.

Note: in _cli, I do argv[argv.index(user) if user in argv else 5] = prompt — that's fragile: …

## 2026-10-04 — One sqlite handle per db path

**Chose:** `_HANDLES` cache in `memory.connect`.
**Because:** Windows raised `sqlite3.OperationalError: database is locked` when
two handles to the same file were open at once, and every verb here opens the
file.
**Rejected:** closing per command — the cache is one line and cannot leak a handle.

Repo is live: https://github.com/<user>n634/rehearsal (36 tracked files, 4 commits).

What changed since your run — your run lost turn 2 (ENGINE: model did not return JSON) and the RAM read printed 0 MiB. Both fixed:

session._call now retries a bad-JSON call once at temperature 0, and the coach budget went 320 → 512 tokens (the failing call hit the cap exactly: n_gen = 320 in the server log). A second failure saves the line and prints (coach call failed — the line is saved, nothing was graded) instead of dying.
record_demo.ram_mib() retries against <local-path>, accepts 1,234 separators, and takes --ram-total/--ram-free overrides.
Duplicate coach corrections are deduped by the said-span, and report.py no longer prints level ?/5 when the model omits level.
tools/stop_llama.py added — a run killed mid-session leaves 2.6 GB resident. I used it; nothing is resident now (/health → refused).

Run this, in this order, from .venv in cmd:

:: 1. prove the engine talks, one call, ~18 s
python run.py doctor --engine server

:: 2. the demo you want for the post — close Strata FIRST, then:
python tools/record_demo.py --scenario cafe-aoi --turns 5 --script docs/demos/script-cafe-aoi.txt --engine server --tag demo

[thinking] ram_mib returns (0,0) even though systeminfo works standalone. So something inside the function differs. Let me debug: print the raw output inside the same process.

Possibly subprocess.run(["systeminfo"], ...) fails with FileNotFoundError in this Python (no PATH lookup for .exe without extension? On Windows, subproc …

[thinking] Regex is fine. So why (0,0)? Maybe import re is missing in record_demo.py → NameError caught by... no. Let me check imports and whether the function body is the one I think (maybe an older duplicate definition later in the file overrides it!). grep showed only one def ram_mib? Let me check.

[thinking] Auth works (empty list). Now, to submit: try presign path for the large payload.

presign_agent_session_upload returns a presigned S3 URL + key presumably. Then I PUT the JSON file to that URL (via Python urllib), then submit with s3_key.

Let me call presign.

[thinking] Note: the LEAKWORDS regex includes <local-path> which will flag legitimate scrubbed text? No, <local-path> is a path — should be scrubbed. But it also flags the word "C:" in prose like "<local-path>— that's a Windows system path, arguably fine to keep, but it's also a machine path. Fine to scrub.

Careful: `<local- …

[thinking] The session-dir names encode the cwd path (<session-dir>). Add a scrub rule: --C--Development-<local-path>[a-z-]*-- → <session-dir>, and generally --(?:C--)?[A-Za-z0-9]+(?:-[A-Za-z0-9]+)*-- too broad. Simple: replace <local-path> → <cwd> and Development in that context... Let me add a specific regex for t …

[thinking] Right — overlapping edits. Do one edit: replace the scrub function with the counting version, and add SUBS dict before it in the same replacement.

[thinking] Now update main() to print SUBS counts as evidence, and keep the gate (leaks() will now find ~0 because LEAKWORDS is substituted; still useful as a check on the final blob).

Let me edit main's print line.

[thinking] Only 1 drive substitution happened?! That means the DRIVE regex isn't matching most paths — because scrub is applied per-block and the SUBS counter is overwritten by the LAST scrub call (each call overwrites SUBS[key]). Yes! text, SUBS[key] = pat.subn(...) overwrites counts. Need +=.

Fix: accumulate.
