Diagnoses runtime bugs, crashes, regressions, failing CI/CD pipelines, and underspecified user reports through read-only, evidence-first root-cause analysis with traceable reports and bounded subagent workflows.
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
# Diagnosing Root Causes Use this skill to diagnose a reported problem from supplied resources and deliver an evidence-backed RCA report. The orchestrator classifies the issue, manages clarification and conditional approval gates, routes work to specialist subagents, and keeps conclusions traceable. Raw artifacts stay in subagent contexts; the orchestrator retains only bounded summaries, verdicts, approvals, and drafts. Execution is a finite state machine. Canonical tables: [`state-machine.md`](./state-machine.md). ## Inputs | Input | Required | Example | | ------------------ | -------- | ------------------------------------------------------------------------------------ | | `ISSUE` | Yes | "Deploy job fails after dependency update" | | `RESOURCES` | Yes | `logs/build-42.txt`, repo paths, CI URL, commit range | | `ISSUE_SOURCE` | No | `runtime`, `CI/CD`, or `user-report` | …

How to install
mdr add b-mendoza/agent-skills/diagnosing-root-causes@sha256:64ce13ab3ccb71c2The line at the top of this page pins the label git:20261014.1603723, 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.
