How Claude Code’s creator ships 50–100 PR’s per week

lassiecoder — Mon, 16 Feb 2026 15:20:46 +0000

When Boris Cherny, the creator of Claude Code, shared his daily workflow on X, the development community took notice. Not because of some revolutionary technique or complex setup, but for the opposite reason: his approach is remarkably straightforward. And that’s precisely why it works.

If you’re looking to supercharge your development workflow with AI, here’s how one of the people building these tools actually uses them.

The core philosophy: Parallelism over speed

Boris runs approximately 10 Claude sessions in parallel at any given time. Instead of babysitting each one, he relies on system notifications to alert him when human input is needed. This approach transforms AI from a back-and-forth conversation tool into something more akin to having a team of junior developers working simultaneously on different tasks.

The key insight here is understanding that AI assistance doesn’t have to be sequential. You’re not limited to one task at a time. By spinning up multiple sessions, you’re essentially multiplying your capacity to tackle problems.

Opus 4.5 with thinking: Slower tokens, faster results

While many developers gravitate toward faster models for quick iterations, Boris exclusively uses Claude Opus 4.5 with thinking enabled. Yes, it’s slower per token. But here’s the counterintuitive truth: it’s faster overall.

Why? Because it requires far less human steering. When you use a more capable model that can reason through problems, you spend less time course-correcting, clarifying, and re-explaining. The AI gets it right more often on the first try, which means you’re not stuck in revision loops.

Think of it like hiring: you might pay more per hour for a senior developer, but they’ll complete the project in a fraction of the time a junior would need.

The 2,500-token secret weapon

The Claude Code team maintains a single shared Claude.md file, checked directly into their Git repository. Whenever Claude behaves incorrectly or misunderstands something, they add a new instruction to this file.

The surprising part? After continuous refinement, this file sits at just around 2,500 tokens. That’s remarkably concise for a document that encodes the team’s entire workflow, conventions, and common pitfalls.

This approach is brilliant in its simplicity. Instead of re-explaining your coding standards, architectural decisions, and preferences in every new conversation, you build up a knowledge base that travels with your code. It’s version-controlled, it’s collaborative, and it evolves with your project.

Plan first, execute once

Boris starts most sessions in plan mode. He iterates on the plan until it feels solid and well-thought-out. Only then does he switch to autonomous mode.

The result? The task usually gets done in one shot.

This two-phase approach mirrors how experienced developers naturally work. You don’t just start coding immediately. You think through the problem, consider edge cases, map out the architecture, and only then do you write code. By forcing this separation with AI, you ensure the execution phase has clear direction.

Sub-agents for specialized tasks

Rather than using Claude as a monolithic tool, Boris employs specialized sub-agents for specific purposes:

Code Simplifier handles post-generation cleanup, refactoring verbose code into something more maintainable.

Verify App runs end-to-end testing to ensure the generated code actually works in practice.

This division of labor is another stroke of genius. Different tasks require different contexts and goals. By creating specialized agents, you’re optimizing each one for its specific role rather than trying to make a single prompt do everything.

Let Claude verify its own work

Perhaps the most interesting aspect of Boris’s workflow is his strong belief in letting Claude verify its own work. He allows it to use a Chrome extension to open a browser, test the UI, and iterate until the code actually functions correctly.

This creates a feedback loop that’s incredibly powerful. Instead of you manually testing and reporting back what’s broken, the AI can see the results of its work and self-correct. It’s the difference between giving someone directions and letting them use GPS.

The output: 50–100 pull requests per week

With this setup, Boris completes approximately 50 to 100 pull requests per week. Let that sink in. That’s anywhere from 10 to 20 PRs per day.

For context, many developers consider 5–10 meaningful PRs per week to be highly productive. Boris is operating at roughly 10x that rate.

Why vanilla workflow works?

In the comments on his original post, many people pointed out that his workflow is pretty vanilla and straightforward. There’s no exotic prompting technique, no complex orchestration system, no proprietary tooling.

And that’s exactly why it works so well.

The most sustainable, scalable workflows aren’t built on clever hacks or cutting-edge techniques that might break with the next model update. They’re built on solid principles: parallelism, proper planning, specialization, and verification.

Key takeaways for your workflow

If you want to adopt Boris’s approach, here are the core principles to implement:

Run multiple sessions in parallel. Don’t wait for one task to complete before starting another. Let the AI work on several things simultaneously while you focus on high-level orchestration.

Invest in better models upfront. The most capable model with extended reasoning might seem slower, but it saves time by getting things right the first time.

Build and maintain a project-specific instruction file. Create your own Claude.md that captures your conventions, common issues, and preferences. Keep it concise and version-controlled.

Separate planning from execution. Get the plan right before switching to autonomous mode. A solid plan executed once beats a vague idea iterated ten times.

Create specialized agents. Instead of one general-purpose prompt, build focused sub-agents for cleanup, testing, and other recurring tasks.

Enable self-verification. Give your AI the tools to check its own work and iterate without constant human intervention.

The future is already here

What’s remarkable about Boris’s workflow isn’t that it’s revolutionary. It’s that it’s achievable today, with tools that are publicly available. You don’t need to wait for the next model release or some breakthrough in AI capabilities.

The gap between where most developers are and where they could be isn’t technological. It’s methodological. Boris has simply figured out how to structure his work to leverage AI’s strengths while minimizing its weaknesses.

The best part? His approach isn’t proprietary or complex. It’s vanilla. It’s straightforward. And that means you can start using it today.

What aspects of this workflow are you most excited to try?
Have you experimented with running multiple AI sessions in parallel?

I Never Planned on Becoming a Google Developer Expert

lassiecoder — Sun, 27 Apr 2025 19:43:17 +0000

But the Path Is Starting to Make Sense

Becoming a Google Developer Expert (GDE) was never on my radar, at least not in the beginning. I didn’t start contributing to the community with a title or badge in mind. I was just building things, breaking things, and sharing whatever I learned along the way. That’s still the core of what I do, but now I’ve realized something important: the things I’m already doing, and the things I want to do more intentionally, are exactly the steps that lead toward becoming a GDE.

I’m not a GDE yet. But I’ve taken the time to understand what the program is really about, and what kind of contributions it values. So if you’re like me, someone who’s active in the community and curious about leveling up, here’s what I’ve learned so far about how to get on the path.

Share What You Know – Consistently and Publicly

One of the biggest realizations I had was this: you don’t need to know everything, but you do need to share what you do know.

That can take a lot of forms:

Writing blog posts or tutorials
Making YouTube videos or live streams
Posting technical threads on X (Twitter) or LinkedIn
Creating code samples or open-source libraries

The key isn’t perfection, it’s consistency and authenticity. People want to hear how you solved something, even if you’re not the “official” expert on it. I’ve started putting more time into documenting what I learn and pushing it out publicly. Even short posts or small demos can go a long way.

Contribute to Open Source (Even in Small Ways)

Contributing to open source isn’t just about building massive libraries. It could be fixing a bug, improving documentation, creating example apps, or reviewing pull requests.

It shows that you’re engaged with the community and care about making tools better for everyone. I’ve made it a point to pick projects I actually use and contribute wherever I can, even if it’s just improving the README or opening helpful issues.

Speak at Events — Online or Offline

Public speaking used to scare the hell out of me. But it’s one of the most effective ways to share knowledge, especially when you can break down complex topics in a way that clicks for others.

You don’t need to start with a massive conference. Local meetups, developer groups, and virtual events are all great starting points. I’ve been slowly getting more comfortable with this, giving talks, joining panels, or even doing short webinars or Q&As. Every session is a chance to grow and give back.

Be Active in Developer Communities

This can be as simple as answering questions on Stack Overflow, Reddit, or Discord servers. Or offering help in Slack groups, GitHub Discussions, or even in the YouTube comments under your favorite tech channels.

When someone gets stuck, and you help unblock them, that’s real impact. It doesn’t have to be flashy to be meaningful.

Focus on a Niche or Technology You Genuinely Love

GDE’s are recognized for their expertise in a specific domain. Whether that’s Firebase, Android, Web, TensorFlow, Google Cloud, or something else, find what you’re excited about and go deep.

For me, that’s [insert your tech focus here — e.g., Firebase or Web Performance]. I try to stay up to date, build real-world projects with it, and share what I learn. Not because I have to, because I genuinely enjoy it.

Be Visible, But Stay Genuine

This is where intention matters. Visibility helps, writing, speaking, building in public, but it only works when it’s rooted in real curiosity and a desire to help others.

You can’t fake this stuff for long. And frankly, you don’t need to. If you’re solving real problems and being open about your journey, the right people will notice. That’s how most GDE’s I’ve talked to got discovered, someone noticed their consistent work and nominated them.

You Need to Be Nominated — So Build Relationships

You can’t just apply to be a GDE, someone in the program (or at Google) has to nominate you. That’s why it helps to engage with existing GDE’s, Google Developer Groups (GDGs), or Googlers themselves.

But don’t network just to “get in.” Build genuine connections. Learn from others, ask questions, collaborate, show up. I’ve found that just being part of the ecosystem naturally opens these doors over time.

Where I’m At Now

I’m still on this journey. I’m putting more effort into sharing what I know, being involved in the community, and leveling up my public contributions. Not for the title, but because I know the process itself will make me a better developer, speaker, teacher, and teammate.

If the GDE nomination comes one day, great. If not, I’ll still be doing the work that matters to me, and that’s what really counts.

If you’re thinking about aiming for GDE too, my advice is simple: start contributing in the way that feels most natural to you. Build, share, teach, connect. Keep showing up. That’s the real path, and it starts right where you are.

Project IDX + Gemini: Transforming How You Write Code

lassiecoder — Sun, 06 Apr 2025 11:52:36 +0000

Project IDX boosts your productivity with AI-assisted code suggestions from Gemini in IDX. Before you use any of the inline assistance from Gemini in IDX, make sure you add Gemini to your workspace.

Use suggested code with caution. Gemini in IDX is in preview and might give inaccurate responses. Validate all AI-assisted code and adapt it to your needs before using it in a real project.
Additionally, if you don't want your prompts used as training data to improve Gemini in IDX, don't use the chat assistant and turn off code completion in your workspace Settings.

Get code suggestions from Gemini in IDX

Gemini in IDX generates complete blocks of possible code inline. To use the Gemini inline code assistance, follow these steps:

Open your IDX workspace. If you haven't already, add Gemini to your workspace.

Go to the file or line of code you want help with and press Cmd + I (on MacOS) or Ctrl + I (on Windows/ChromeOS/Linux).

Enter a description of what you want and Gemini in IDX generates a suggestion. You can also use actions as shortcuts to guide the suggestions. For example, enter /fixError for help fixing errors in inline code.

To keep the generated code, click Accept. To paste the suggestion somewhere else or move it to a new file, select the corresponding option from the drop-down menu on the Discard button. To generate a new suggestion, click the Regenerate icon. To remove the suggestion completely, click Discard.

Tip: You can also use Interactive Chat with Gemini to instruct Gemini in natural language to perform actions directly in your workspace on your behalf, like updating code and running commands.

View Gemini commands inline

To view Gemini in IDX commands inline, for specific code, select and right-click the code you want help with.

Select Gemini from the menu and then select the action you want to perform.

Use Gemini suggested code completion

To help you write code, IDX provides AI-enabled suggested code completion that predicts and autofills code in any open file as soon as you begin to type. Suggested code completion is turned on by default.

To accept a code suggestion, press Tab. To ignore the suggestion, just keep typing.

To toggle code completion on or off, adjust your code completion settings.

Open the Settings window by clicking the gear icon or pressing Ctrl + , (on Windows/Linux/ChromeOS) or Cmd + , (on MacOS).
Search for the IDX > AI > Enable Inline Completion setting in the Workspace settings.
To turn off code completion, deselect the Enable inline code completion as you type option. You have to update code completion settings for each of your workspaces.

If you use a settings.json file, set "IDX.aI.enableInlineCompletion": false.

You can adjust this option under both the Workspace and User settings, but adjusting it in the Workspace settings ensures that the setting persists if the VM your workspace is connected to restarts. In IDX, User settings don't apply across your workspaces.

Once you've turned suggested code completion on, Gemini provides AI-assisted code suggestions. To accept a code suggestion, press Tab. To ignore the suggestion, just keep typing.

Exclude files from Gemini .aiexclude files

You can control which files from your codebase should be kept hidden from Gemini in IDX by including .aiexclude files in your project. This lets you granularly control the project context you share with Gemini.

Much like a .gitignore file, an .aiexclude file tracks files that shouldn't be shared with Gemini in IDX, including the chat experience as well as AI features that operate in the editor. An .aiexclude file operates on files at or below the directory that contains it.

Note: Files ignored by .gitignore files in your repository are automatically excluded, even if they're not listed in .aiexclude file.

Files covered by .aiexclude won't be indexed by Gemini when Codebase Indexing is enabled. Additionally, .aiexclude will affect inline assistance for covered files in the following ways:

Chat assistance: Gemini won't be able to answer questions or offer suggestions about files covered by .aiexclude.
Code completion: Suggested code completions will not be available when editing covered files.
Inline assistance: You'll be able to generate new code, but not modify existing code when editing covered files.

Other development environments such as Android Studio may also honor .aiexclude files.

How to write .aiexclude files

An .aiexclude file follows the same syntax as a .gitignore file, with the following differences:

An empty .aiexclude file blocks all files in its directory and all sub-directories. This is the same as a file that contains **/*.
.aiexclude files don't support negation (prefixing patterns with !).

Examples

Here are example .aiexclude file configurations:

Block all files named apikeys.txt at or below the directory that contains the .aiexclude file:

apikeys.txt

Block all files with the .key file extension at or below the directory that contains the .aiexclude file:

*.key

Block only the apikeys.txt file at the in the same directory as the .aiexclude, but not any subdirectories:

/apikeys.txt

Block all files in the directory my/sensitive/dir and all subdirectories. The path should be relative to the directory that contains the .aiexclude file:

my/sensitive/dir/

Wrapping Up

Gemini in Project IDX represents a significant advancement in AI-assisted development. By integrating its inline code suggestions, command access, and smart completion features into your workflow, you can dramatically reduce development time while maintaining control over which parts of your codebase the AI can access.

As you explore these capabilities, remember that Gemini is still in preview — always review its suggestions carefully and adapt them to your specific project needs. The power of combining your expertise with AI assistance creates a development experience that's both efficient and flexible.

Try implementing these features in your next Project IDX session and see how they transform your coding process!

Gemini AI in Chrome DevTools

lassiecoder — Wed, 02 Apr 2025 07:38:24 +0000

Hey devCommunity! 👋

I've got something incredible to share with you today that's completely changing the game for web developers. Google has integrated Gemini AI right into Chrome DevTools, and let me tell you – it's absolutely mind-blowing!

Why This Is a Big Deal?

Remember those days when we'd spend hours debugging code or searching Stack Overflow for answers? Those days might be behind us. Imagine having an AI assistant right inside your development environment, helping you debug, optimize, and understand code in real-time. That's exactly what Google has delivered!

Here's a glimpse of some game-changing features!

Exclusive: Hidden Gems I've Discovered

Here are some lesser-known features I've found while exploring:

Code Refactoring Suggestions: Gemini can analyze your entire JavaScript file and suggest modern patterns and best practices. It's like having an automated code review!

Simplifying Software Architecture: Understanding MVC, MVP, and MVVM

lassiecoder — Sun, 02 Feb 2025 21:08:43 +0000

Understanding software architecture patterns is very important as applications grow more complex.

All patterns share two core components: the Model (handling data and business logic) and the View (managing user interface).

MVC uses a Controller as a traffic coordinator, allowing direct Model-View communication. MVP employs a Presenter as a strict mediator, ensuring all communication flows through it. MVVM introduces data binding through a ViewModel, automatically syncing data changes with the View.

Choose MVC for simpler web applications, MVP for highly testable systems, and MVVM for data-heavy applications with complex UIs. Companies like Stack Overflow, Google, and Apple use these patterns based on their specific needs.

In order to understand it in simplistic terms, I've covered it briefly in my newsletter scoop.

Git <> Common Developer Pitfalls and Solutions

lassiecoder — Sat, 24 Feb 2024 12:38:57 +0000

Git, essential for version control, poses challenges for developers. Let's explore some common issues and their fixes:

“error: failed to push some refs to 'git@github.com:USERNAME/REPOSITORY.git'” Occurs when pushing changes to a remote repository, indicating local and remote repositories differ

Solution: Pull latest changes from remote with git pull, resolve conflicts, then push changes with git push

“error: pathspec 'file.txt' did not match any file(s) known to git” Triggered when referencing a non-existent file in the repository

Solution: If encountering a Git error for a non-existent file, ensure correct filename spelling; create a new file using touch file.txt if needed. If accidentally deleted, restore from backup or use a recovery tool, then add to the repository with git add file.txt and commit changes via git commit -m "Restored file.txt"

“error: failed to clone some remote refs” Occurs during cloning due to issues with the remote repository

Solution: Confirm remote repository existence, verify access permissions. Seek collaborator status for private repos.

“fatal: not a git repository (or any of the parent directories): .git” Occurs outside a repository. Results from not initializing or misplacing .git directory

Solution: Ensure within Git repo. If not, navigate to directory, initialize repository with git init

“error: Your local changes to the following files would be overwritten by merge” Arises when pulling changes clashes with local modifications

Solution: Resolve conflicts with merge tool, save changes, commit, then retry pulling

Understanding and addressing these Git challenges is important for effective version control. Utilize Git documentation, forums, and Stack Overflow for assistance. Master Git to streamline collaboration and code management.

Happy coding! 🙌🏼

Error handling in React 18

lassiecoder — Sat, 24 Feb 2024 12:34:16 +0000

React 18 enhances error handling, preventing app crashes by catching and managing errors in child components.
An error boundary component captures errors from its children, updating the state on error using getDerivedStateFromError and componentDidCatch logs the errors.

Here are 10 key improvements:

Concurrent Mode: The latest version of React introduces Concurrent Mode, streamlining UI responsiveness by breaking large updates into smaller, prioritized pieces, with the ability to pause and resume updates, preventing main thread blockage.
Suspense: It's awesome because it lets your components hold off on rendering until they've fetched all the data they need. This means you can make your app look way better while it's loading stuff, instead of just showing a boring blank screen or a spinner.
Server Components: They're a special kind of component that you can render on the server and then send over to the client as HTML. It's like giving your app a speed boost, especially for folks visiting for the first time without a cached version of your site.
Automatic Batching: In older versions of the library, you had to manually group updates together to keep your app running smoothly. But in this latest release, this grouping happens automatically. That means you can update multiple things at once without having to do any extra work to optimize performance.
Improved Profiling: This version of React has better profiling tools, making it simpler to analyze and optimize your app's performance. These new tools let you track how long each component takes to render, helping you spot any performance issues.
Improved Accessibility: In this iteration, there are updates that enhance accessibility, catering better to users with disabilities. One notable addition is the focus-visible attribute, aiding keyboard users in identifying which element is currently in focus.
New APIs: For instance, the useTransition hook enables creating animations based on user actions. Similarly, the useDeferredValue hook helps delay processing costly computations.
Improved Hydration: The latest version boosts hydration, the method of rendering server-generated HTML on the client. The updated process is quicker and more effective, enhancing your app's performance.
Improved Error Handling: This release enhances error handling, simplifying debugging and issue resolution. The updated error boundary API enables you to capture and manage errors within individual components, preventing them from causing app-wide crashes.
Improved Developer Experience: This version boosts developer experience with features like “startTransition” API for deferred rendering after state updates, easing asynchronous code writing. Also, the “component stack traces” offer detailed error information, aiding quick issue identification and resolution.
