cf-sys-debug skillA

cf-sys-debug is agent-read markdown (skill) from dinhanhthi/coding-friend: Systematic 4-phase debugging — root cause, hypothesis testing, regression-guarded fix, mandatory bug doc. Auto-invoke for non-trivial or recurring bugs — signals: "still broken", "same error again", "came back", flaky/intermittent/race, "used to work, now broken", hard-to-reproduce, works locally fails in CI, "find the root cause", "investigate", "diagnose", "why is this happening". Prefer over cf-fix for hard bugs. Do NOT auto-invoke for trivial typos, one-line fixes, or obvious config errors..

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 dinhanhthi/coding-friend/cf-sys-debug@git:20260827.d3037e2
Exact content
mdr add dinhanhthi/coding-friend/cf-sys-debug@sha256:6364a15fd3da800a

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.
