StaleDocs

StaleDocs

Formerly aidoc.

StaleDocs reads your code, finds public API changes in a pull request, and tells you which documentation sections now describe the old behavior.

Add to a repository in one file

name: StaleDocs review

on: {pull_request: {types: [opened, synchronize, reopened]}} permissions: {contents: read, pull-requests: write} jobs: review: runs-on: ubuntu-latest steps:

• uses: actions/checkout@3d3c42e5aac5ba805825da76410c181273ba90b1 with: {fetch-depth: 0}
• uses: mr-min-max/staledocs@v0.5.0-beta.2 with: mode: review fail-on: none

What the comment contains

• Changed symbols with before and after signatures.
• Sections that mention them and were not updated.
• breaking-change and docs-stale labels when applicable.

No model, no API key, no writes. It is deterministic AST analysis.

From the terminal

Install the command:

npm install -g staledocs

staledocs review reports documentation impact for a pull request.

staledocs plan prints the affected documentation targets.

staledocs check exits with code 1 when a section mentioning a changed public symbol was not updated, and exits 0 otherwise.

Audit a repository once

staledocs audit lists the package scripts, repository paths, and public class members that your Markdown still mentions but the code no longer has, including AGENTS.md, CLAUDE.md, and the copilot-instructions.md file under .github, the files coding agents read first. It needs no pull request. The command is new in 0.5.0-beta.1.

npm install -g staledocs

staledocs audit

Output on a small fixture repository:

README.md > Usage: member-missing "Client.fetchAll"

README.md > Usage: path-missing "src/core/old.ts" README.md > Usage: script-missing "npm run bulid" (closest: build)

3 findings across 1 Markdown file: script-missing 1, path-missing 1, member-missing 1.

Fix the docs with your assistant

Codex plugin

Start Codex in your Git worktree, then run:

codex plugin marketplace add mr-min-max/staledocs

codex plugin add staledocs@staledocs

In a new session, type $ and pick staledocs:check, staledocs:review, or staledocs:maintain-documentation (or open /skills). Requires Node.js >=22.12.0 and npm/npx. This repository hosts its own plugin marketplace; it is not a listing in OpenAI's plugin directory.

Claude Code plugin

Start Claude Code in your Git worktree, then run:

/plugin marketplace add mr-min-max/staledocs

/plugin install staledocs@staledocs

Use /staledocs:check for drift signals, /staledocs:review for the PR report, or /staledocs:maintain-documentation for a validated draft. Requires Node.js >=22.12.0 and npm/npx. This repository hosts its own plugin marketplace; it is not an approved Anthropic directory listing.

Manual MCP

codex mcp add staledocs -- staledocs --mcp

prepare_documentation_update gives the assistant the exact sections and before and after signatures.

StaleDocs validates the candidate, and the assistant applies the approved Markdown.

See the Codex guide and Claude guide.

Languages

TypeScript, JavaScript, and Python are supported. A public symbol is one reachable from the package entry; see LIMITATIONS.md for syntax and discovery caveats.

Legacy generators

readme, api, changelog, diagram, and annotate remain available for initial documentation. They need a provider key or Ollama and are not the focus of StaleDocs. See the CLI catalogue.

Status and links

StaleDocs 0.5.0-beta.2 is the current release. npm latest, npm beta, and the GitHub Action v0 tag point to the current release, and the official MCP Registry lists it as io.github.mr-min-max/staledocs.
