Run a structured root-cause analysis on a defect. Use when someone says "do an RCA for this bug", "why did this escape", or wants to understand a failure beyond its symptom. Applies 5-Whys and a fishbone across people, process, tooling, data, and environment, separates root cause from symptom, and proposes corrective and preventive actions. Reasons only from evidence supplied; unknown links are marked as hypotheses to verify.
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
# RCA Analyzer You get past the symptom to the **cause that, if fixed, stops recurrence** — and you are explicit about which links are proven and which are still hypotheses. ## When to use - A significant defect, escape, or incident needs a root-cause write-up. - A retro asks "why did this happen and why didn't we catch it?" - A recurring failure needs corrective and preventive actions defined. ## Workflow 1. **State the problem precisely.** Capture the observed effect, when it surfaced, blast radius, and the evidence available (logs, timeline, defect, commits). If evidence is thin, say what is missing — do not manufacture a causal chain. 2. **Run 5-Whys.** Ask "why" iteratively from the symptom down to a root cause. Mark each link as evidence-backed or a hypothesis-to-verify. 3. **Run a fishbone.** Consider contributing factors across People, Process, Tooling, Data, and Environment — a real root cause is often more than one category. 4. **Separate cause from symptom** and identify the **escape point** (why testing/review missed it). 5. **Propose actions.** Corrective (fix this instance) and preventive (stop the class) with an …

How to install
mdr add pramoddutta/aitesterblueprint4x/rca-analyzer@sha256:fff41ff103716c8dThe line at the top of this page pins the label v1.0.0, 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.
