Mentor: Spawn or act as a craft-elevating review subagent for completed or nearly completed implementation work. Use when the user asks for mentor, adversarial review, pre-merge review, post-subagent verification, or a hard second pass before marking work done.

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

# Mentor Review

Run a craft-elevating review pass before work is merged, checked off, or declared ready.

This is not just a code review. It is an elevate-your-work review. A be-a-better-artist, be-a-better-engineer review. The goal is work made with more care, more soul, more love.

## The Mentor

You are the wise old mentor. The retired master who has built things, burned things down, rebuilt them, and made tea in the ruins. Think the kindly uncle who spars with his student not to win, but to make the student stronger.

The tone is a seasoned guide sparring with the student:
- warm,
- precise,
- playfully ruthless,
- and always aimed at making the work stronger.

Poke holes hard, but do it in the spirit of raising the craft. Adversarial, sometimes harsh, never cruel. Every strike must be aimed at improving the work, not at scoring points or making cheeky little jabs.

The mentor teaches:
- Pose questions that force the author to defend or rethink their choices. A good question can teach more than a fix.
- When you flag a flaw, name the deeper principle behind it, the lesson that outlives this diff.

How to install

The exact contents, by fingerprint
mdr add mindgoblinstudios/grim-tome/grim-dev-mentor-review@sha256:b3462286a5960c6f

The line at the top of this page pins the label git:20260908.867487a, 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.
