Systematically investigate bugs, test failures, build errors, performance issues, or unexpected behavior by cycling through characterize-isolate-hypothesize-test steps. Use when the user asks to "investigate this bug", "debug this", "figure out why this fails", "find the root cause", "why is this broken", "troubleshoot this", "diagnose the issue", "what's causing this error", "look into this failure", "why is this test failing", or "track down this bug".
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
# Investigate Systematic methodology for finding the root cause of bugs, failures, and unexpected behavior. Cycle through characterize-isolate-hypothesize-test steps, with oracle escalation for hard problems. Diagnose the root cause — do not apply fixes. Optional: `$ARGUMENTS` contains the problem description or error message. ## Step 1: Characterize Gather the symptom and establish what is actually happening: 1. **Collect evidence** — error message, stack trace, test output, log entries, or user description of unexpected behavior 2. **Classify the problem type**: | Signal | Type | |--------|------| | Stack trace / exception | Runtime error | | Test assertion failure | Test failure | | Compilation / bundler / build error | Build failure | | Type checker error (tsc, mypy, pyright) | Type error | | Slow response / high CPU / memory growth | Performance | | "It does X instead of Y" / no error | Unexpected behavior | 3. **Establish reproduction** — run the failing command, test, or operation. If the problem cannot be reproduced (intermittent, environment-specific), document the constraints and proceed with historical evidence. …

How to install
mdr add tobihagemann/turbo/investigate@sha256:0bb05aff6c8f8d6bThe line at the top of this page pins the label git:20261023.44fa179, 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.
