Use when investigating a software defect, failing test, flaky behavior, remote-environment anomaly, or unexplained UI or API behavior. Reproduce, localize, and prove the cause with an evidence chain across source, runtime, data, middleware, deployment, and client boundaries; stay read-only unless the request also asks for the fix. Do not use for planned database writes or for reviewing a diff.
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
# Rumo Debug Turn a symptom into the shortest causal chain that evidence can prove. ## Authority Investigation is read-only by default. Fixing code, changing data, restarting services, or editing configuration needs the original request to include the fix or a separate go-ahead. Database writes always go through `rumo-database-change-safety`. ## 1. Pin Down The Facts Record the affected repository or service, environment and its purpose, exact time window (convert "this morning" into timestamps before querying logs), client or actor version, expected and actual result, reproduction steps, identifiers, and error text. Use `rumo-project-profile` when project-specific paths, hosts, or schemas are needed; otherwise discover from the repository and ask only for facts that cannot be established safely. ## 2. Reproduce Reproduce at the cheapest layer that shows the symptom. If it does not reproduce, compare environment, data, version, and timing before guessing. For flaky behavior, find the condition that makes it deterministic. ## 3. Localize 1. Find the visible entry point: route, screen, command, scheduled job, message, import, or protocol action. …

How to install
mdr add rumoii/rumo-engineering-skills/rumo-debug@sha256:fbe2b30f1eba44bbThe line at the top of this page pins the label git:20261018.1527838, 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.
