Description
I built a Claude Code skill called crabby that makes Claude output diagnostics in rustc error format - severity codes, location arrows, causation spans, and a paste-able fix every time. The twist: Claude becomes Ferris the crab, grumpy and unimpressed, but technically precise.The format works for code review, writing review, architecture, strategy - anything you submit. The "writing review" example tends to surprise people: it flags passive voice in a postmortem with the exact same error[W002] format as a SQL injection.https://github.com/ekadetov/crabby
