GitHub Copilot CLI GitHub Copilot CLI reads, writes, and runs code where you work. Code faster, smarter, together.

Alright, uhhh, I'm just gonna say it:

You fuckin' goobers are really underestimating Copilot CLI. As far as my work is concerned, it's just as good as Claude Code

Like, it's legit good: github.com/features/cop...

How to Stop Claude Code from Burning Its Context Window on Noise (RTK on Windows) RTK cuts 80-99% of token waste from build output, git commands, and test runs. Here's how to get the automatic hook working on Windows, since the installer won't do it for you.

When worlds collide: software engineering meets AI engineering YouTube video by Jo Van Eyck

🎥 "When Worlds Collide: Software Engineering meets AI Engineering"

Software engineering and AI engineering are often treated as separate disciplines. In practice, they're converging fast, and the people who'll thrive are the ones comfortable dancing between both.

Lots of teams are shipping changes faster than they can understand.

This gap is cognitive debt; and it compounds quickly, especially with AI coding agents in the picture. Let's look at 5 techniques I apply to stay in touch.

Dual-loop BDD is the new Red-green TDD This one goes out to all the testing neophytes who only recently realized (https://simonwillison.net/guides/agentic-engineering-patterns/red-green-tdd/) that it's useful to have an automated means of verifying their code does what it claims to do. For the last month, I've been working on prove_it (https://github.com/searls/prove_it), a framework for building quality harnesses for Claude Code (https://claude.com/product/claude-code)—primarily via its hooks system (https://code.claude.com/docs/en/hooks). In a recent release, I added TDD enforcement to its default configuration. First, it injects a test-first development approach into every plan Claude generates. Then, a PreToolUse hook follows up with permissionDecisionReason reminders whenever the agent deviates from the one true path (e.g., repeatedly edits source files without touching any tests, never runs a test to see it fail, etc.).

I put together a piece on how I'm doing co-design with agents in some of my dev work at the moment, and how there's a very specific through line from XP and the sort of software design and intentionality I talk about often.

Safely Refactor Production Codebases with AI Breaking API migrations, hidden coupling, and large-scale rewrites — done safely with AST-backed AI workflows.

agentic AI + large codebases = 💩
AI + LSP + large codebases = 💡

On March 14th I'll be attending the virtual event "Safely Refactor Production Codebases with AI" to look for more tools fit for legacy code!

AI should help us produce better code
simonwillison.net/guides/agent...

AI twitter's favourite lie: everyone wants to be a developer Twitter's latest consensus on inevitability: now that large language models can write code, everyone will become a software developer. People, you see, have problems, and software solves problems, and AI removes the barrier between people and software, therefore everyone will build their own software. It's a syllogism, after a fashion,

The average punter does not want to build software.

They don't want to prompt software.

They don’t even want to describe software.

If your job was to know when to hit the semicolon key on the keyboard, I'm sad to say that's not an employable skill anymore.

If you shape ideas into tools and art via code, it's really so much better than ever now, and I don't see that changing soon.

I started a new chapter of my Agentic Engineering Patternw guide about anti-patterns - things NOT to do

So far I only have one: Inflicting unreviewed code on collaborators, aka dumping a thousand line PR without even making sure it works first simonwillison.net/guides/agent...

This seems like a super relevant tool to counter the whole "cognitive debt" issue wrt AI coding tools. How feasible do you think it would be to generate these kinds of diagrams highlighting a batch of AI driven changes, e.g. a PR's worth, focusing more on the delta rather than the entire codebase?

This is the way!

You should be looking for velocity, not just speed. Speed lacks direction.

More autonomy requires more constraints, not just bigger specs.

Key to efficient learning is realizing how we ACTUALLY learn, not just what FEELS like learning. I wrote a Claude Skill for some friends to help them think about this and they've liked it -- see Principles for some directions you could explore

Short musings on "cognitive debt" - I'm seeing this in my own work, where excessive unreviewed AI-generated code leads me to lose a firm mental model of what I've built, which then makes it harder to confidently make future decisions simonwillison.net/2026/Feb/15/...
