rot-canary skillA

rot-canary is agent-read markdown (skill) from hetcreep/coalmine: Code-health scan — dead code, bug-prone logic, resource leaks, concurrency bugs, silent failures, input-boundary issues, doc rot. Triggers on: "/rot-canary", "rot-canary", "code-health" (legacy aliases: "/rotcanary", "rotcanary"). Auto-runs at session end on touched files (QUICK, report only) via platform hooks — auto-wired by the Claude Code plugin, manual elsewhere. Run manually for fix mode. Reports; fixes on request via choice-gated menu..

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

Latest version
mdr add hetcreep/coalmine/rot-canary@git:20260903.0a4f5d3

mdr add hetcreep/coalmine/rot-canary@sha256:40e949e437c8dced

Pin 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.
