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

# Repository guidance

## Purpose

Maintain an accurate, engineering-first learning guide for OpenAI Codex.

## Editing rules

- Keep product behavior aligned with official OpenAI documentation.
- Label community practices and opinions clearly.
- Do not add credentials, destructive examples, or full-access defaults.
- Keep modules progressive: outcome, concepts, exercise, verification, sources.
- Keep skill bodies concise; put optional detail in direct `references/`.
- Preserve attribution to `luongnv89/claude-howto` as inspiration.
- For work that depends on prior decisions, experiments, or established Codex
  guidance, read `knowledge/index.md` first and load only relevant pages.
- Treat wiki queries as read-only unless the user explicitly requests capture,
  ingest, archive, or promotion.

## Pull requests

This personal open-source repository does not require Jira tickets. Use a
descriptive branch and PR title; link relevant GitHub issues when applicable.

## Validation

Run:

```bash
python3 scripts/validate_repo.py
python3 skills/maintain-codex-wiki/scripts/wiki_lint.py .
```

For each changed skill, also run:

```bash

How to install

The exact contents, by fingerprint
mdr add phelan164/codex-howto/AGENTS.md@sha256:e8c8bd7f2408c5e4

The line at the top of this page pins the label git:20260915.dd80dad, 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.
