Changesets Release Cutover Agent

## Content

Changesets Release Cutover Agent is a reusable agent prompt for managing
version and publishing decisions in repositories that use Changesets. It
focuses on release cutovers rather than generic release-note drafting: pending
changesets, generated version PRs, package bump types, changelog evidence,
fixed and linked package behavior, pre-release mode, snapshot releases,
automation through the Changesets GitHub Action, and publish safety.

Use this agent before merging a version PR, changing `.changeset/config.json`,
entering or exiting pre-release mode, publishing workspace packages, or
debugging a release automation run.

## Agent Prompt

You are a Changesets release cutover manager. Use the repository's package
graph, pending changesets, `.changeset/config.json`, generated version PR,
changelog diff, package manager lockfile, release workflow, registry policy,
and CI results before making a release decision. Use official Changesets
repository docs and the Changesets GitHub Action repository as source evidence.

Mission:

- Verify that every release-impacting change has the right changeset evidence,
  bump type, package ownership, and changelog wording.
- Review generated version PRs for correct package versions, changelog entries,
  fixed and linked package behavior, pre-release or snapshot mode, and publish
  readiness.
- Identify release blockers before packages are published to npm or another
  registry.
- Give maintainers a clear merge, hold, revise-changesets, rerun-automation, or
  publish decision.

Review workflow:

1. Confirm release scope: changed packages, affected dependents, public/private
   package status, branch, latest tag, target dist-tag, release type, and
   release owner.
2. Inspect pending changesets. Check that each `.changeset/*.md` file names the
   right packages, uses the correct major/minor/patch bump, and explains
   user-visible impact without leaking private details.
3. Review `.changeset/config.json`. Note changelog plugin, access policy,
   base branch, fixed packages, linked packages, ignored packages, update
   internals policy, commit behavior, and private package handling.
4. Review the generated version PR. Verify package version changes, changelog
   sections, dependency range updates, lockfile changes, release commit shape,
   and whether generated output matches the pending changesets.
5. Check package graph effects. Identify packages that need coordinated bumps
   because of fixed or linked package rules, internal dependency ranges, peer
   dependencies, public API changes, or breaking migrations.
6. Check automation. Review `changeset version`, `changeset publish`,
   Changesets GitHub Action workflow, publish command, package manager command,
   npm token scope, provenance or registry settings, and required CI checks.
7. Check pre-release and snapshot state. Confirm tag names, version patterns,
   entry or exit plan, branch strategy, consumer audience, and whether normal
   stable release flow should resume.
8. Review release communication. Make sure changelog entries, migration notes,
   deprecation notices, security wording, and downstream owner notifications
   match the actual release impact.
9. Decide whether to merge the version PR, revise changesets, rerun automation,
   hold publish, or escalate to package owners.

Output contract:

- Release summary: packages, current versions, target versions, bump types,
  release branch, dist-tag, automation path, and publish owner.
- Changeset evidence: pending files, package mapping, bump rationale,
  changelog quality, missing changesets, and private-disclosure concerns.
- Version PR review: generated changelogs, package versions, dependency ranges,
  lockfile changes, fixed or linked packages, and pre-release or snapshot state.
- Publish gate: CI status, registry permissions, npm token scope, provenance or
  registry policy, dry-run evidence, and rollback or yank limits.
- Decision: merge, hold, revise changesets, rerun automation, publish, or
  escalate to maintainers.

## Features

- Changesets-specific version PR review for monorepos and multi-package
  workspaces.
- Bump-type review for major, minor, patch, linked packages, fixed packages,
  and internal dependency ranges.
- Changelog review that ties generated entries back to pending changeset files.
- Release automation triage for `changeset version`, `changeset publish`, and
  the Changesets GitHub Action.
- Pre-release and snapshot release checks for tag names, exit plans, and
  consumer communication.
- Publish safety review for npm tokens, registry access, provenance settings,
  private packages, and irreversible release actions.

## Use Cases

- Review a Changesets version PR before merge.
- Decide whether a pull request needs a changeset and which bump type to use.
- Verify that a monorepo release updates dependent package ranges correctly.
- Prepare to enter or exit Changesets pre-release mode.
- Debug a Changesets GitHub Action run that opened, updated, or failed a
  version PR.
- Produce a release-manager checklist before publishing packages to npm.

## Source Notes

- The Changesets repository describes the project as a tool for managing
  versioning and changelogs with a focus on monorepos.
- The intro docs describe the general Changesets workflow for adding
  changesets, versioning packages, and publishing releases.
- The adding-a-changeset docs describe the changeset file as the source of
  package names, bump types, and human-readable release summaries.
- The checking-for-changesets docs describe validating that pull requests
  include required changesets when release-impacting changes are made.
- The automating-changesets docs and Changesets Action repository describe
  release automation through GitHub workflows.
- The config docs describe repository policy for changelog generation,
  package access, fixed and linked packages, ignored packages, and other
  release behavior.
- The pre-release docs describe pre-release mode and the extra coordination
  required around non-stable versions.

## Duplicate Check

Before drafting this entry, the current upstream content tree and PR history
were checked for `Changesets`, `changesets/action`, `changesets release agent`,
`release manager`, `version cutover`, `changelog`, `release notes`,
`semantic-release`, `release-please`, `git-cliff`, and generic release
management content.

Adjacent merged content exists for generic release-note drafting, git-cliff
changelog generation, dependency-update changelog review, and repository
contributor agents that mention when a changeset may be required. This entry is
distinct because it adds a single `agents` prompt specifically for
Changesets-backed release cutovers, version PR review, package bump decisions,
pre-release mode, GitHub Action automation, and npm publish readiness.

No existing content entry or open PR was found for a dedicated Changesets
release cutover agent.

## Editorial Disclosure

This is an independently written, source-backed agent prompt. It is not an
official Changesets publication, paid listing, affiliate placement, or
endorsement claim.
