Had a blast at RubyConf Vienna, chapeau to all the speakers, artists (yes there was music) and organisers @misabegovic.bsky.social @hansschnedlitz.com & team.

So many programming legends on a single stage! #Ruby #Python #Elixir

📢 Undercover gem v0.8.5 just shipped, featuring: - new --format=json CLI option, which the Claude Code skill likes more than the default text format - small fix for Ruby 4 compat

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?

Undercover 0.8.4 just dropped with an important bugfix to coverage reported for branched statements spanning multiple lines ✨ github.com/grodowski/un...

"Absolutely essential for ensuring our AI agent-written PRs have the coverage we require." This is why I build tools, thanks for the shoutout @jaytennier.bsky.social 🙏

Big shout out to undercover-ci.com the code coverage tool we use at @rainforestqa.bsky.social. It's always been great as a pre-release gut-check but lately it's become absolutely *essential* for ensuring our AI agent-written PRs have the coverage we require.

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!

Just pushed pronto-undercover 0.4.0 to RubyGems! 🎉 ICYMI, it's a great way to integrate undercover with any SCM and any CI workflow and now it supports latest undercover again
