diagnosing-bugs skillA

diagnosing-bugs is agent-read markdown (skill) from aethrox/doctrine: Systematic debugging discipline based on David Agans' nine rules, understand the system, reproduce reliably, bisect the search space, change one variable at a time, keep an audit trail, and never declare a fix done until it's verified against the original failure. Use when the user reports something broken, throwing, failing, or slow, or says "diagnose" / "debug this"..

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 aethrox/doctrine/diagnosing-bugs@git:20260809.2a45dbb
Exact content
mdr add aethrox/doctrine/diagnosing-bugs@sha256:afdcb7f70093fcc2

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.
