Really enjoyed listening to @maintainable.fm with @jayroh.dev. My highlights: - retroactively added tests often skim over real code flaws - high test coverage != quality - understanding why a test is difficult to write guides you to a better architecture maintainable.fm/episodes/joe...

Currently working with two Claude Code's on a plugin that sets up and effectively uses undercover for coverage feedback loops. Claude A is developing the skill. Claude B is a mock project that uses it with --plugin dir. It's been a struggle! Does this mean we need a skill-writing skill?

Been running ads for Undercover lately with a simple message: your 90% coverage is hiding untested methods, especially in AI-generated code changes. Undercover catches what coverage percentages miss, right in your PRs and local workflow. If you saw them, I'd love to hear how the message landed!

Sponsoring @shortruby.com this week again, with updated messaging. It's now easier than ever to produce thousands lines of code at speeds that make automatic review needed even more. Undercover guides your coding agent to write complete and higher quality tests.
