root-cause-by-layer skillA

root-cause-by-layer is agent-read markdown (skill) from corvinlabs/corvinos: Use when encountering a bug, failing test, or unexpected behavior — especially under time pressure where try/except, retry loops, xfail, type-tolerance shims, "I'll clean up later," or compat-for-both-shapes feel like the fastest path. Forbids symptom patches until structural and conceptual origins are named..

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

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.
