Investigate code debugging and root-cause narrowing; use measurable gates before fixes.
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
> Before asking, read [User Questions](../../shared/codex-user-questions.md).
# Investigate
> Task-size routing follows [Proportional Execution](../../shared/native-skill-contract.md#proportional-execution); this skill's specialized lifecycle and acceptance checks remain authoritative.
See the [fixed recurrence and root-cause policy](../../shared/native-skill-contract.md#recurrence-and-root-cause-policy) and [reasoning-progress escalation policy](../../shared/native-skill-contract.md#reasoning-progress-escalation) for repeated-obstacle handling; record and validate `reasoning-progress.json` before another cycle after escalation trigger.
Diagnosis-first loop for unclear failures: failing tests, tracebacks, regressions, surprising runtime behavior. Produce root-cause claim with evidence, falsification, rejected alternatives before any fix. Use `investigate` until root cause established; then hand off to `implement` or `code-remediate`.
## Input Schema

"symptom": "required failing command, traceback, runtime bug, CI failure, flaky behavior, or tool anomaly",

How to install
mdr add borda/ai-rig/investigate@sha256:e508177788390c23The line at the top of this page pins the label git:20261031.2278c0c, 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.
