Use when the user reports a hard bug, unexpected failure, or performance regression that needs root-cause analysis.
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 A discipline for hard bugs and regressions. Skip phases only when explicitly justified. All questions and findings reported to the user must be in **Portuguese (pt-BR)**. When exploring the codebase, use the project's domain glossary from `.claude/CONTEXT.md` (if it exists) to get a clear mental model of the relevant modules, and check `docs/architecture/` for decisions and ADRs in the area you are touching. **Re-validation loop**: after every hypothesis, fix, or change, re-run the reproduction and the regression checks before declaring the bug resolved. **Iron rule:** NO FIXES WITHOUT A RED LOOP AND A CONFIRMED ROOT CAUSE. A change made before Phase 1 produced a red signal and Phase 4 confirmed a hypothesis is a guess — and guessing under pressure is how one bug becomes three. This holds ESPECIALLY under time pressure, when the bug "looks simple", and after a previous fix already failed: those are exactly the moments the process pays off. Violating the letter of this process is violating the spirit of debugging. ## Pipeline ```text Phase 0 Frame the bug → symptom, expected vs actual, env, frequency, scope …

How to install
mdr add afonsoft/skills/diagnose@sha256:15c932cccde6fe24The line at the top of this page pins the label v1.5.0, 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.
