Why

Publish this repository as a native pre-commit hook provider so consumer repositories can regenerate README sections without maintaining a local hook definition.

Changes

  • Add .pre-commit-hooks.yaml with hook id github-action-readme-generator.
  • Use a repository-owned language: unsupported_script wrapper rather than installing this full development repository as a Node hook environment.
  • The wrapper reads the selected provider revision's package.json version and executes that exact npm release with npx.
  • Require pre-commit 4.4.0+, where unsupported_script is the current name for this non-isolated script hook type.
  • Run on every commit with pass_filenames: false so consumer-supplied action and README paths can be forwarded without staged filenames.
  • Add an integration smoke test using pre-commit try-repo.

Verification

The smoke test exercises the real consumer path on Node 24.19.0 and pre-commit 4.6.2:

  1. validate .pre-commit-hooks.yaml;
  2. clone this PR at its exact SHA through pre-commit try-repo;
  3. run the hook against a disposable consumer repository containing a stale README;
  4. require the first run to modify the README with content from action.yml;
  5. stage that result and require a second run to pass without changing it again.

This end-to-end test is now green. Existing repository lint, unit/build checks, CodeQL, and real-world integration tests remain the other merge gates.

The hook requires Node/npm in the consuming environment; the supported Node range is defined by this package's engines field. Consumer documentation using the floating v2 tag is intentionally deferred until the release workflow has published this hook and promoted v2 to that release.

Summary by CodeRabbit

  • New Features
    • Added a pre-commit hook that generates README sections from the GitHub Action configuration.
    • The published hook runs the package version matching the selected repository revision, uses the consumer’s Node.js and npm installation, and runs on every commit without limiting generation to staged files.
    • Action and README paths can be configured.
  • Documentation
    • Updated setup instructions with the published hook configuration, its execution behavior, and supported Node.js requirements.

Walkthrough

The pull request adds a published pre-commit hook that runs the README generator at the package version associated with the repository revision. It updates the setup instructions and adds an integration workflow that checks generation in a consumer fixture.

Changes

Published pre-commit hook

Layer / File(s) Summary
Define and document the published hook
.pre-commit-hooks.yaml, scripts/pre-commit-hook.sh, README.md
The manifest registers the hook without filenames. The launcher checks for node and npx, then runs the matching npm package version. The README explains how to configure the published hook.
Verify hook behavior in a consumer fixture
.github/workflows/integration-test.yml
The workflow validates the hook configuration, checks that the first run updates docs/ACTION.md but not README.md, and confirms that the next run leaves docs/ACTION.md unchanged.

Consumers following the README cannot install the hook until a release containing it is published and v2 is updated. Coordinate that release before treating the documented setup as available.

🟡 Minor · The guidance does not establish support for arbitrary configuration-file… · README.md:161-169

README.md:161-169
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

The guidance does not establish support for arbitrary configuration-file paths.

The hook and CLI load .ghadocs.json from the consumer working directory. The CLI exposes action and README path options, but no configuration-file selection option. Therefore, a consumer that stores configuration under another filename cannot use that file through the published hook.

Clarify the sentence to refer only to configurable action and README paths, or document and implement a configuration-file path option.

🟠 Major · Publish the hook before documenting rev: v2. · README.md:157-169

README.md:157-169
🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Publish the hook before documenting rev: v2.

v2 currently resolves to eaab4d23d4449592cff854d46525af5aab287ac4 (v2.0.7), but that revision has no .pre-commit-hooks.yaml. A consumer following this example cannot register github-action-readme-generator.

Publish a release that includes the manifest, then move v2 to that release before using it in the README. The smoke test does not cover this case because it uses the pull-request SHA instead of v2.
