release-readiness-protocol— agent skill

Purpose

Confirm a release is correct, documented, validated, publishable, and reversible before any external write such as a tag push, package publish, or GitHub release.

When to Use

• Cutting a new version of a library, CLI, or service.
• Before git tag, npm publish, gh release create, or equivalent.
• When release steps span multiple systems or targets.
• When a release needs a go/no-go decision with rollback steps.

Inputs

• Intended version number or bump type
• Current package metadata
• Last release tag or compare base
• Changelog or release notes draft
• Publish target such as npm, PyPI, Docker, or GitHub Releases

Workflow

1. Version check

Read the current version from the relevant manifest and verify the target does not already exist:

npm view <pkg>@<version> version
pip index versions <pkg>
cargo search <pkg>

Confirm bump type:

• Breaking change -> major
• New user-facing capability -> minor
• Bug fix, catalog/doc correction, or asset polish -> patch

2. Compare range and change summary

git describe --tags --abbrev=0
git log <last-tag>..HEAD --oneline --no-merges
git diff --stat <last-tag>..HEAD

Flag breaking changes, release-note gaps, and user-visible assets that changed.

3. Metadata check

• README reflects current behavior.
• Manifest fields include description, license, homepage, repository, files, and publish config.
• No placeholder or TODO text appears in published metadata.
• Package contents match catalog paths.

For npm packages:

npm pack --dry-run

4. Validation gate

Run the full release suite for the project:

npm test
npm run build
python scripts/validate-skills.py
python scripts/validate-catalog.py

If a repository has a release preflight command, prefer it:

npm run release:check

5. Publish plan

Write exact commands before executing them:

git tag vX.Y.Z -m "Release vX.Y.Z"
git push origin vX.Y.Z
npm publish --access public
gh release create vX.Y.Z --verify-tag --title "vX.Y.Z" --notes-file <notes>

Wait for explicit approval before the first irreversible step.

6. Rollback plan

Output

RELEASE READINESS: go / no-go
Version: X.Y.Z
Compare range: <last-tag>..HEAD
Changelog coverage: complete / gaps
Breaking changes: yes / no
Validation: <commands and result>
Publish plan: <exact commands>
Rollback plan: <exact commands>
Blockers: <none or list>

Verification

• [ ] Version does not already exist in the target registry.
• [ ] Compare range was reviewed.
• [ ] Changelog or release notes cover user-visible changes.
• [ ] Release validation commands exited 0.
• [ ] Package contents were checked when publishing a package.
• [ ] Rollback plan was written before tag or publish actions.

Failure Modes

• Releasing from a dirty working tree.
• Tagging a version already published.
• Trusting generated release notes without checking the compare range.
• Running publish commands before rollback is documented.
• Treating a GitHub Release as proof that package publishing succeeded.
