It's so satisfying to delete the obsolete crates.io tokens from my account, now that all my crates use trusted publishing. ☺️

An interesting side effect of using coding agents is that my GitHub Issues have become much more detailed. Mostly as context to the agents when they plan. But I've benefited from that so much already, both in easier context switching between tasks and better onboarding for new contributors.

I love that we're discussing the use of .unwrap() in #Rust today, but I'm wondering how actionable the discussion is for most maintainers? I've found designing good error types one of the hardest challenges in API design.

I'm trying out GitHub's Spec Kit with Claude Code today and I have so many questions. Feels like something is missing in the toolkit that enables small units of change while still allowing the AI to drive the design. Will report back later...
