debug skillA

debug is agent-read markdown (skill) from genai-io/san: Systematic debugging that finds the root cause before changing any code — collect symptoms, trace the code path, check what changed, reproduce deterministically, form a testable hypothesis, then fix the cause (not the symptom) and prove it with a regression test. Use when the user reports a bug, a crash, a failing test, or says "debug", "why is this happening", "root cause"..

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 genai-io/san/debug@git:20260717.120e9bb
Exact content
mdr add genai-io/san/debug@sha256:b2557159d9e3c5ff

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.
