diagnose skillA

diagnose is agent-read markdown (skill) from pitimon/8-habit-ai-dev: Active bug investigation discipline — 6-phase methodology covering feedback-loop, reproduce, hypothesise, instrument, fix-with-regression-test, and cleanup-with-post-mortem. Use when investigating a hard bug or performance regression that doesn't have an obvious root cause. Triggers: "diagnose", "debug this", "investigate this bug", "reproduce the failure", "why is X failing". Read-only guidance — guides the human through systematic investigation rather than auto-fixing. Refuses to skip Phase 1 .

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.

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.
