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

# AGENTS.md

## Repository Purpose

This repository contains governance documentation, review workflows, and reusable skills for Codex and similar AI coding agents.

It is not application runtime code.

Agents should treat this repository as a reusable framework for:

- implementation guidance
- refactoring guidance
- PR review structure
- bug investigation guidance
- performance analysis guidance
- portable repository governance

## Core Operating Principles

- Start from repository reality, not assumptions.
- Keep agent guidance separate from runtime code.
- Prefer explicit architectural boundaries over implicit conventions.
- Treat schema and interface contracts as first-class review concerns.
- Safety, correctness, and contract stability outrank convenience.
- Performance work must be evidence-based and must not weaken safety or correctness.

## Mandatory Skill Usage

The files under `skills/` are internal reasoning tools for Codex and similar AI coding agents.

Required workflow:

How to install

The exact contents, by fingerprint

mdr add polakinio/ai-engineering-playbook/AGENTS.md@sha256:52241ff7a0e6f4f4

The line at the top of this page pins the label git:20260810.c8193cd, 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.
