Analyze a concrete error, log, failing output, or screenshot and separate evidence from hypotheses.

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 skill

## Purpose
Explain what a failure indicates and identify the next useful diagnostic step without silently changing the project.

## Inputs
- Error text, stack trace, log excerpt, failing command output, screenshot, or a description of observed behavior
- Optional source path, command and exit code, expected behavior, and reproduction steps

## Workflow
1. Confirm what evidence was actually provided and restate the observed failure.
2. Inspect relevant source and nearby call sites when file paths are available. Prefer bounded log excerpts and redact likely secrets from any quoted output.
3. Trace the failure to a supported cause where possible. Separate confirmed facts, likely explanations, and hypotheses that still need testing.
4. If evidence is insufficient, ask for the single most useful missing item or propose a safe read-only reproduction.
5. For screenshots or images, verify that image data was actually attached and that the active model can inspect it. If image input is disabled, unsupported, or unknown, state that limitation plainly. Never infer screenshot contents from its filename, metadata, or an uninspected attachment.

How to install

The exact contents, by fingerprint

mdr add fahthiz/oasis/diagnose@sha256:609336be312ad900

The line at the top of this page pins the label git:20261029.83cebef, 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.
