I can drop ideas directly into the Claude app on my iPhone and get 80% of the implementation of the idea done by the time I get back to a laptop to finish it off

80% of the implementation of the idea done

In the thread “Ask HN: How are you automating your coding work?”

Helped: Clean test suite setup allowing TDD workflow and mobile usage.

… This means I can run Claude Code against any of my repos and tell it "run 'uv run pytest', then implement ..." - which is a shortcut for having it use TDD and write tests for the code it's building, which is essential for having coding agents produce working code that they've tested before they commit. Once this is working well I can drop ideas directly into the Claude app on my iPhone and get 80% of the implementation of the idea done by the time I get back to a laptop to finish it off. I wrote a bit about "uv run pytest" and dependency groups here: https://til.simonwillison.net/uv/dependency-groups
