Reproduce a failure and narrow it to an evidence-backed root cause before fixing.
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
# Rig Investigate > Read [Evidence rules](../../references/evidence.md). A plausible explanation is not a root cause. ## Input - Symptom, failing command, stack trace, or behavior. - Known environment and versions. - Paths or subsystem hints. ## Workflow 1. **Start the run.** `rig_evidence` with `action: "start"`, `skill: "rig-investigate"`, and candidate paths. 2. **Reproduce with real inputs.** Run the failing command. If it does not reproduce, record the exact difference and stop rather than guessing. 3. **Shrink the case.** Remove unrelated configuration and files until the smallest failing case remains. Record each removal. 4. **List hypotheses.** Write at least two plausible causes. For each, name the observation that would disprove it. 5. **Test one at a time.** Change one variable per run. Record the command, output digest, and conclusion. Optional: dispatch read-only `rig-investigator` children for independent hypotheses; they share the tree, so they must not edit files. 6. **Confirm the cause.** Show the failing behavior disappearing when the cause is removed, or explain why that experiment is unavailable. …

How to install
mdr add borda/ai-rig/Rig Investigate@sha256:8128accfa4e8baf5The line at the top of this page pins the label git:20261027.5ca9910, 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.
