Writes or updates READMEs, guides, API references, runbooks, ADRs, and changelogs for a specific reader. Use when the user asks for a README, documentation, a guide, a runbook, a changelog, an ADR, or an API reference. Not ordinary chat answers or external-documentation research.

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

1. Identify the reader, task, and existing source of truth. Match each changed behavioral claim to implementation, configuration, a versioned contract, or an executed example. Distinguish shipped behavior, unreleased changes, proposals, and unknowns. Preserve the project's document language and format.

2. Choose the needed form using [Diataxis](https://diataxis.fr/). A tutorial teaches through a guided exercise, a how-to completes a task, a reference specifies facts, and an explanation develops understanding. Keep these reader needs distinct without imposing a repository-wide reorganization. Link to maintained facts rather than copying them.

3. Include the content the requested artifact needs.

- A README identifies purpose, supported setup, the shortest verified route to first use, and links to detailed material.
- A guide states prerequisites, supported versions, working directory, ordered actions, and observable success conditions. Put access requirements and data-changing consequences beside the affected action.
- An API reference specifies actual inputs, defaults, outputs, errors, and access restrictions.

How to install

The exact contents, by fingerprint

mdr add dayfinggg/openai-codex-agent-skills/documentation@sha256:9221ea283b0ce002

The line at the top of this page pins the label git:20261105.e0d5bb2, 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.
