rule-miner skillA
rule-miner is agent-read markdown (skill) from vanducng/skills: 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 doe.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add vanducng/skills/rule-miner@v0.1.0mdr add vanducng/skills/rule-miner@sha256:9eba714b469e4060Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
