systematic-debugging skillA

systematic-debugging is agent-read markdown (skill) from sethgammon/citadel: 4-phase root cause analysis: observe, hypothesize, verify, fix. Enforces investigation before any code changes. Emergency stop after 2 failed fixes. Prevents shotgun debugging and fix cascades..

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 sethgammon/citadel/systematic-debugging@git:20260624.445e974
Exact content
mdr add sethgammon/citadel/systematic-debugging@sha256:f673e7bf5f8e7ff2

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.
