Root-cause a bug before touching a fix: reproduce, isolate, form and test a hypothesis, confirm the cause, then fix and verify. Stops guess-driven patching. For persistent, intermittent, or "already tried a few things" bugs.
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 Debugging <!-- routing-eval reads the next line; why it sits in the body: AGENT_TEMPLATE.md --> Trigger phrases: "debug", "root cause", "why is this failing", "intermittent bug", "can't reproduce", "is broken", "crashes" One rule holds the whole skill together: **no fix without a confirmed root cause.** A patch that makes the symptom disappear without a proven cause is not a fix — it's a coin flip that hides the bug until it returns somewhere worse. This skill is the discipline that turns "try things until it works" into "understand, then change one thing." > **Crewforth adaptation (local, .claude/):** Distinct from `iterate` (a self-correction loop over a *task*) and `reflect` > (meta-review of an approach) — this skill is for a *defect*. §4 Prohibitions apply; a fix still goes through the > project's review/test gates. Don't disable a test or a gate to make a symptom pass (that is masking, not fixing). ## The loop (do them in order — skipping a step is why bugs come back) 1. **Reproduce** — a reliable, minimal repro. Can't reproduce → that IS the first problem; see `references/techniques.md` (intermittent/heisenbug). …

How to install
mdr add byerlikaya/claude-starter-kit/systematic-debugging@sha256:42e07e4bd59c54fbThe line at the top of this page pins the label git:20260926.aaa5dbc, 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.
