Systematically analyze bugs, failures, or unexpected behavior to identify root causes. Examines code, data, dependencies, and logs without proposing fixes, producing a structured analysis that surfaces assumptions, evidence, gaps, and the simplest path forward.
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
# Root Cause Analysis Skill ## Overview Structured investigation workflow for understanding problems completely before proposing fixes. This skill produces a detailed analysis document that: - Maps the problem systematically across code, data, and dependencies - Identifies and challenges assumptions - Documents evidence and gaps - Ranks candidate root causes by probability - Suggests the simplest possible solutions (without writing code) **Announce at start:** "I'm using the root-cause-analysis skill to investigate this problem systematically." **Critical Rule:** Do NOT write, edit, or suggest any code changes. This is a thinking-only skill that surfaces what to fix, not how to fix it. --- ## When to Use This Skill ✅ Investigating unexpected behavior or errors in production or development ✅ Understanding why a test is failing repeatedly ✅ Diagnosing performance degradation or system failures ✅ Analyzing data corruption or inconsistent state ✅ Understanding third-party library issues or integration failures ✅ Tracing complex issues that span multiple services or layers ❌ Code review or style improvements (use relevant code standards) …

How to install
mdr add sean-m-cooper/ai_tools/root-cause@sha256:c12ca75056601cc6The line at the top of this page pins the label git:20260407.7b9ec8a, 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.
