Hunt

When your fix doesn't stick or you're stacking patches on symptoms, this skill forces you to stop and diagnose first. It won't let you touch code until you can state the root cause in one sentence with evidence. Includes bisect mode for regressions, screenshot reference mode for visual bugs, and scope blast to find every other place the same pattern is hiding. The hard rules are good: same symptom after a fix is a hard stop, three failed hypotheses means you surface what you've ruled out and ask how to proceed. Designed for errors, crashes, and "it used to work" problems, not code review or greenfield features.
