diagnose-loop SKILL.md skillA
diagnose-loop from ivy00johns/skill-madness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ivy00johns/skill-madness/diagnose-loop@v1.2.1Pins v1.2.1 in mdr.lock. Pin the fingerprint instead.

Disciplined bug diagnosis whose core is building a fast, deterministic pass/fail reproduction first; the later phases run on that signal. Use for hard bugs, flaky tests or performance regressions. Trigger on "diagnose this", "debug this", "why is this broken", "it sometimes fails", "this test is flaky", "I can't reproduce it".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Diagnose Loop > **Tradeoff caveat.** This skill biases toward thoroughness over speed. For trivial bugs with obvious causes (typos, off-by-one, a missing import the stack trace already points at), skip phases and just fix it. For everything else — flaky tests, performance regressions, "it works on my machine," intermittent failures, anything you've stared at for more than 15 minutes — the discipline is the point. Adapted from mattpocock's `diagnose` pattern. > **diagnose-loop vs systematic-debugging.** The plugin skill `superpowers:systematic-debugging` is the general "form a hypothesis before you touch a fix" discipline for any bug or unexpected behavior. Reach for `diagnose-loop` (this skill) specifically when the payoff is in *building a fast, deterministic, binary feedback loop first* — flaky tests, performance regressions, hard-to-reproduce or intermittent failures. For a straightforward bug where you just need disciplined hypothesizing, `superpowers:systematic-debugging` is the lighter fit. ## Phase 1 — Build a feedback loop (THE SKILL) **Spend disproportionate effort here. Be aggressive. Be creative. Refuse to give up.** …

How to install
mdr add ivy00johns/skill-madness/diagnose-loop@sha256:3e8ec1b81921a684The line at the top of this page pins the label v1.2.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
