Codex documentation skills for READMEs and API docs
Codex documentation skills write the docs you keep putting off. This page is for developers, open source maintainers and tech writers who need a README, an API reference or release notes that match the code. A skill drafts; you check the result against the code before you publish.
Codex documentation skills by task
READMEs: README Generator builds a README from your manifests, and README Rescue Architect for AI Coding Agents tackles repositories with no docs at all. Tip: run it after the install steps work, so the README describes reality.
API and CLI reference: api docs gen turns source code into OpenAPI or Markdown, and Cli Ux Doc Builder covers CLI help text. Tip: regenerate in the same pull request as the code change, so docs and code never drift.
Release notes and commits: Changelog & Release Notes Generator and Changelog Generator build notes from git history; smart commit and Git Commit Writer write commit messages from the staged diff, and PR Template Generator drafts pull request descriptions. Tip: pick one per job, since several overlap.
Specs and postmortems: PRD Writer and codex spec interviewer draft specs, and incident postmortem writes blameless postmortems. Tip: keep finished specs in the repo next to the code they describe.
Which documentation skill to pick
Start with the doc that costs you most time each week. As of October 2026, README Generator, Git Commit Writer and codex spec interviewer are free, and the others are paid, from $5 for PR Template Generator and Cli Ux Doc Builder to $15 for Changelog & Release Notes Generator. A doc skill that writes files edits your repo, so review its diff before you commit and check the scan result, users and updates.
Connect Codex to Agensi once, then ask for a skill by name or let Codex load it when the task fits. The latest approved version loads for that session and nothing is saved to .agents/skills. Our guide to connecting tools to Codex CLI and the MCP setup guide cover the setup.
Documentation skills and AGENTS.md in Codex
Codex reads AGENTS.md every time, so it suits fixed conventions such as your commit format. A skill loads only when the task fits, so templates wait until you need them. Our guide to AGENTS.md in Codex CLI explains the split, and our best documentation skills for AI agents compares more.

Frequently asked questions
