systematic-debugging skillA
systematic-debugging is agent-read markdown (skill) from fmind/dot: Diagnose failures, DNS/TLS, and Python CPU or memory issues with Pyinstrument and Memray..
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.
What the file says
# Systematic Debugging Replace guess-and-check with an evidence loop that localizes where and why behavior diverges; [python-testing](../python-testing/SKILL.md) implements the fix and [incident-response](../incident-response/SKILL.md) owns live outages. ## Workflow 1. **Preserve evidence**: Capture the exact error, stack trace, command, inputs, versions, environment differences, timing, and recent changes before touching anything. 1. **Reproduce**: Find the shortest reliable command or sequence; for intermittent failures record the frequency and vary one dimension at a time. 1. **Reduce**: Minimize input, fixture, process count, and component path while keeping the same failure, preferably as a focused test or disposable harness. 1. **Localize**: Trace bad state backward across calls, processes, network boundaries, configuration, and generated artifacts; at each boundary compare what entered with what left. 1. **Find a working comparator**: Locate the nearest known-good test, code path, version, environment, or commit and list every relevant difference before choosing one. …

How to install
mdr add fmind/dot/systematic-debugging@git:20260919.4491844mdr add fmind/dot/systematic-debugging@sha256:ec2a0e5c678d79c7Pin 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.
