systematic-debugging skillA

systematic-debugging is agent-read markdown (skill) from flieber-inc/devcake: Four-phase root-cause debugging — investigate, pattern-match, hypothesize, then fix. Use when facing a bug, test failure, build break, unexpected behavior, or flaky path, before proposing or shipping a fix. Forbids symptom patches without a causal chain. Companion: verification-before-completion for proof after the fix; test-driven-development when encoding the fix as a test..

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 flieber-inc/devcake/systematic-debugging@git:20260720.fa58fb9
Exact content
mdr add flieber-inc/devcake/systematic-debugging@sha256:71ea22180affba62

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.
