type:audit type:review

Mine your Claude Code sessions and code-review history for the corrections you keep repeating, cluster them, adversarially verify each candidate, and distill the survivors into CLAUDE.md rules — or check that existing rules still hold. Uses a dynamic Workflow harness with one verifier per rule to avoid false positives. Use when the user says 'mine my sessions for rules', 'what corrections do I keep making', 'turn my repeated feedback into CLAUDE.md rules', 'audit my CLAUDE.md rules', or 'why does Claude keep missing X'.

Turn the corrections you keep making into durable rules — and keep the rules you already wrote honest. It runs as a dynamic [Workflow](#how-it-runs): separate agents with their own context windows, so verification can't be biased by the agent that proposed the rule.
