Phase-based root cause investigation: reproduce, observe, hypothesize, bisect, verify. TRIGGER when: investigating a bug report, diagnosing unexpected behavior, or doing root cause analysis. SKIP: looking up a known error first (use sofa-search); writing the regression test (use testing-strategy); live-repro watcher (use watch-patterns).
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 Skill ## Purpose A repeatable root cause investigation procedure. A bug is not understood until it can be reproduced on demand and the causal chain is traced back to a fixable defect. This skill encodes the phase order and the discipline (one variable at a time, bisect instead of scan, verify by reverting) that keeps an investigation from turning into guesswork. ## When to Apply Apply this skill when: - Investigating a reported bug or unexpected behavior - Diagnosing a failing test, crash, or incorrect output - Performing root cause analysis before recommending a fix - An error message, stack trace, or log output needs to be traced to its origin Do NOT apply this skill for: - Writing the regression test that prevents recurrence — use `testing-strategy` - Constructing the poll/watch loop used to observe a live reproduction — use `watch-patterns` - Looking up a known/unfamiliar error before investigating from scratch — use `sofa-search` --- ## Investigation Phases Work the phases in order. Do not skip ahead to a fix before phase 6. | Phase | Action | Exit Criterion | |-------|--------|-----------------| …

How to install
mdr add komluk/scaffolding/systematic-debugging@sha256:c7b14eaed2bdd5a3The line at the top of this page pins the label git:20260921.7dfd510, 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.
