Use when a defect, regression, intermittent failure, or performance symptom needs evidence-led reproduction and causal diagnosis before a fix; use advanced-testing-strategy to design broader test coverage.
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
# Systematic Bug Diagnosis Convert a reported symptom into a small red-capable feedback loop, falsify ranked hypotheses, and return a supported cause or an explicit evidence gap. Diagnosis is read-only by default; fixing is a separate authorised action. <!-- dual-compat-start --> ## Use When - A bug report, regression, flaky test, crash, data discrepancy, latency spike, memory growth, or production-only symptom needs diagnosis. - Several plausible causes exist and changing code before reproducing the symptom would be guesswork. - A prior fix failed, moved the symptom, or introduced a neighbour regression. ## Do Not Use When - The task is broad test strategy without a concrete symptom; use `advanced-testing-strategy`. - The cause is already proved and the user has asked for implementation; route to the owning domain skill while retaining the reproduction as a regression oracle. - Production instrumentation, sensitive data access, or disruptive execution lacks authority. ## Required Inputs | Input | Required | Missing-input response | | --- | --- | --- | | Exact observed symptom and expected behaviour | yes | Clarify or extract from logs/tests before causal claims | …

How to install
mdr add peterbamuhigire/chwezi-dev-engine/systematic-bug-diagnosis@sha256:23b609bb95de2fcfThe line at the top of this page pins the label git:20260911.7afa6ea, 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.
