It's wild to think that with AI, every task suddenly has a concrete price tag. Very curious how that will change prioritization and backlogs...

I find coding agents so helpful for refactoring code. Really feels like the average code quality in my projects has improved massively in the past ~year.

Nothing better than seeing 12 hours of work, 8 stacked pull requests, 42 new files, and half my sanity turn into a single, simple function call that totally hides the madness going on behind it.

Is it just me or is Claude 4.8 weirdly fascinated with spines? It loves to use the spine as a metaphor in my conversation.

There are so many more problems waiting for someone to solve them with a really, really good user experience. Wish we'd value UX designers more in open source projects!

I've been noticing that I let coding agents do their thing in some personal projects, while still keeping a close eye on their output at work. Have been wondering what it would take to close the gap and wrote up a few thoughts:

Can layered specifications, tamper-proof tests, and scoped human review build confidence in AI-generated code?

I got some questions about what people choose to check into git when doing agentic development. Do you check-in
AGENTS.md
? .claude directories or files? Hooks? I also asked in
rustaceans-ai.zulipchat.com
-- if you do Rust coding with agents, you should join that.
loading . . .
AGENTS.md
AGENTS.md is a simple, open format for guiding coding agents. Think of it as a README for agents.
