Debugging as the six geniuses at minute scale — the bug confirmed by a red reproduction before any theory, hypotheses plural with kill-reasons before any fix, the fix proven by a fresh green rerun. Use when something is broken, throwing, failing, flaky, or slow, or when the user asks to debug or diagnose.

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

# Diagnose

A bug is a piece of work whose problem statement nobody confirmed, and debugging fails the way all work fails: at whichever stage got skipped. Read code until a cause feels plausible, fix that, call it done when nothing visibly objects — that is idea straight to implementation at minute scale.

The concept: **the six geniuses, run at minute scale — no ceremony, no work file, the same order.**

- **Wonder — the code confirms the problem.** A bug's confirmation is a red reproduction: one command, run here, that shows the symptom — red while the bug lives, green when it dies. Until it exists nothing is confirmed and no theory has standing; catching yourself building one first is the stop. A flaky symptom is confirmed by rate — raise the reproduction until signal beats noise. Then shrink it: cut inputs, config and callers one at a time, re-running after each cut, until everything left is load-bearing. The wrong bug reproduced is the wrong problem confirmed.

How to install

The exact contents, by fingerprint
mdr add donald-ada/workinggenius/diagnose@sha256:e63e9c28201a29ec

The line at the top of this page pins the label git:20261003.51d9739, 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.
