setup-changesets

name	setup-changesets
description	Set up changesets in a new or existing repository. Use when asked to 'add changesets', 'set up releases', or 'configure versioning'. Handles single packages and monorepos. Detects and migrates from competing release tools. Optionally sets up a shared reusable workflow in a <user/org>/.github repo.

Setup Changesets

Changesets automates versioning and changelog generation. Contributors add changeset files describing their changes; CI consumes them to bump versions, update changelogs, and publish packages.

Step 1 — Gather context

Before doing anything, detect or ask:

Detect automatically:

Check	How
Package manager	Look for pnpm-lock.yaml, bun.lock/bun.lockb, yarn.lock, package-lock.yaml
Monorepo	pnpm-workspace.yaml, workspaces field in root package.json, or bun.workspace.ts
Already initialized	.changeset/ directory exists

Hosting platform (informs CI workflow choice):

Platform	How
GitHub	.github/ directory exists
GitLab	.gitlab-ci.yml or .gitlab/ directory exists
Bitbucket	bitbucket-pipelines.yml exists
Azure DevOps	azure-pipelines.yml exists
Gitea / Forgejo	Self-hosted; ask the user if no platform is detected

Existing CI system (to know which workflow file to create or replace):

CI system	Config file
GitHub Actions	.github/workflows/*.yml
GitLab CI	.gitlab-ci.yml
CircleCI	.circleci/config.yml
Azure Pipelines	azure-pipelines.yml
Bitbucket Pipelines	bitbucket-pipelines.yml
Jenkins	Jenkinsfile
Travis CI	.travis.yml
Drone CI	.drone.yml
AppVeyor	appveyor.yml

Competing release tools (check package.json deps and config files):

Tool	Detection
semantic-release	semantic-release in deps, OR .releaserc / .releaserc.{json,js,cjs,yaml,yml} / release.config.{js,cjs,ts} / "release" key in package.json
release-it	release-it in deps, OR .release-it.{json,js,ts,yaml,yml} / "release-it" key in package.json
standard-version	standard-version in deps, OR .versionrc / .versionrc.{json,js} / "standard-version" key in package.json
beachball	beachball in deps, OR beachball.config.json
release-please	release-please-config.json / .release-please-manifest.json
auto (Intuit)	auto in deps, OR .autorc / .autorc.{json,js}
Nx Release	nx in deps AND "release" key in nx.json
lerna	lerna.json exists
bumpp	bumpp in deps
changelogen	changelogen in deps

If a competing tool is detected, ask before proceeding:

"I found <tool(s)> in this repo. Changesets is a different approach to automated versioning. Do you want to migrate to changesets? I'll remove the old tool and its config, then set up changesets from scratch."

• Yes → follow the Migration section for the detected tool(s), then continue to Step 2
• No → stop here; do not set up changesets

Ask the user:

1. "Do you want to also create a reusable workflow in a <org-or-user>/.github repo, so other repos can share the same release pipeline?"

   • Yes → follow Shared workflow setup after completing local setup
   • No → inline the workflow in the appropriate CI config file

2. If monorepo: "Are any packages versioned together (always share the same version)?" → fixed groups

3. "Are any packages private/internal and should be excluded from publishing?" → ignore list

---

Migration

Remove the old release tool before initializing changesets. Follow the subsection for each detected tool.

semantic-release

1. Remove packages: <pm> remove semantic-release and any @semantic-release/* plugins found in package.json
2. Delete config files (whichever exist): .releaserc, .releaserc.json, .releaserc.js, .releaserc.cjs, .releaserc.yaml, .releaserc.yml, release.config.js, release.config.cjs, release.config.ts; also remove the "release" key if it appears inside package.json
3. Remove any "semantic-release" call from the "release" script in package.json
4. In the detected CI config file(s), find the job/step that runs semantic-release — delete the step or the entire job; note the filename so the new changeset workflow can reuse it
5. Secrets: GH_TOKEN / GITHUB_TOKEN and NPM_TOKEN can be reused as-is

release-it

1. Remove packages: <pm> remove release-it and any @release-it/* plugins
2. Delete config files (whichever exist): .release-it.json, .release-it.js, .release-it.ts, .release-it.yaml, .release-it.yml, release-it.config.js, release-it.config.ts; also remove the "release-it" key from package.json if present
3. Remove any "release-it" call from the "release" script in package.json
4. In the detected CI config file(s), find and remove the step running release-it; note the filename for reuse
5. Secrets: GITHUB_TOKEN and NPM_TOKEN can be reused as-is

standard-version

1. Remove packages: <pm> remove standard-version
2. Delete config files (whichever exist): .versionrc, .versionrc.json, .versionrc.js; also remove the "standard-version" key from package.json if present
3. Remove any "standard-version" call from scripts in package.json
4. standard-version is often run locally rather than in CI; check for any CI step and remove if found
5. Secrets: usually none; NPM_TOKEN reusable if present

beachball

1. Remove packages: <pm> remove beachball
2. Delete config files (whichever exist): beachball.config.json; remove any "beachball" key from root or package-level package.json files
3. Remove change, checkchange, and release scripts in package.json that call beachball
4. In CI config, find and remove the step running beachball release
5. Secrets: NPM_TOKEN reusable

release-please

1. Remove packages: <pm> remove release-please (if installed as a CLI dep); the GitHub Action needs no package removal
2. Delete config files: release-please-config.json, .release-please-manifest.json
3. No package.json scripts to remove (release-please is entirely CI-driven)
4. In .github/workflows/, find and delete the workflow using googleapis/release-please-action
5. Secrets: GITHUB_TOKEN and NPM_TOKEN reusable

auto (Intuit)

1. Remove packages: <pm> remove auto and any @auto-it/* plugins
2. Delete config files (whichever exist): .autorc, .autorc.json, .autorc.js
3. Remove any "auto release" or "auto shipit" calls from scripts in package.json
4. In CI config, find and remove the step running auto release; note the filename for reuse
5. Secrets: GH_TOKEN can be reused as GITHUB_TOKEN; NPM_TOKEN reusable

Nx Release

1. No separate package to remove — nx itself provides the release functionality and stays installed
2. Remove the "release" key from nx.json; remove any nx release targets from project.json files
3. Remove any "nx release" calls from scripts in package.json
4. In CI config, find and remove the nx release step
5. Secrets: GITHUB_TOKEN and NPM_TOKEN reusable

lerna

1. Remove packages: <pm> remove lerna
2. Delete config files: lerna.json
3. Remove any "lerna publish" or "lerna version" calls from scripts in package.json
4. In CI config, find and remove the step running lerna publish
5. Secrets: GH_TOKEN / GITHUB_TOKEN and NPM_TOKEN reusable

bumpp

1. Remove packages: <pm> remove bumpp
2. Delete config: no dedicated config file; remove any "bumpp" key from package.json if present
3. Remove any "bumpp" calls from scripts in package.json
4. In CI config, find and remove any bumpp step
5. Secrets: NPM_TOKEN reusable if publishing was wired up

changelogen

1. Remove packages: <pm> remove changelogen
2. Delete config: no dedicated config file; remove any "changelogen" key from package.json if present
3. Remove any "changelogen" calls from scripts in package.json
4. In CI config, find and remove any changelogen step
5. Secrets: GITHUB_TOKEN reusable if GitHub releases were used

---

Step 2 — Initialize

# pnpm
pnpm dlx @changesets/cli init

# bun
bunx @changesets/cli init

# npm / yarn
npx @changesets/cli init

This creates .changeset/config.json and .changeset/README.md.

Step 3 — Configure .changeset/config.json

Replace the generated config with appropriate settings:

Single package:

{
  "$schema": "https://unpkg.com/@changesets/config@3.0.0/schema.json",
  "changelog": "@changesets/cli/changelog",
  "commit": false,
  "access": "public",
  "baseBranch": "main"
}

Monorepo with grouped packages:

{
  "$schema": "https://unpkg.com/@changesets/config@3.0.0/schema.json",
  "changelog": "@changesets/cli/changelog",
  "commit": false,
  "access": "public",
  "baseBranch": "main",
  "fixed": [["package-a", "package-b"]],
  "linked": [],
  "ignore": ["internal-tools"],
  "updateInternalDependencies": "patch"
}

Key decisions:

• "access": "public" — required for publishing scoped packages (@scope/name) publicly; private packages ignore this
• "fixed" — packages that must always share the exact same version number
• "linked" — packages that share the highest bump type but keep independent version numbers
• "ignore" — packages excluded from changeset versioning entirely (e.g. examples, internal CLIs)
• "commit": false — recommended; changeset version won't auto-commit, giving you control

Step 4 — Add scripts to package.json

{
  "scripts": {
    "version": "changeset version",
    "release": "changeset publish",
    "cs": "changeset"
  }
}

cs is a shorthand for adding changesets during development. version and release are called by CI.

If the project has a build step that must run before publishing, update release:

"release": "pnpm build && changeset publish"

Step 5 — Set up the CI release workflow

Use the CI system detected in Step 1. If the project is on GitHub, prefer Option A or B below. For all other CI systems, use the platform-specific template.

GitHub Actions — Option A (inline workflow)

Create .github/workflows/release.yml:

name: release
on:
  push:
    branches: [main]

concurrency: ${{ github.workflow }}-${{ github.ref }}

permissions:
  contents: write
  pull-requests: write
  id-token: write

jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0

      # Insert package manager setup here (see below)

      - run: <install-command>
      - run: <build-command>        # remove if no build step

      - name: Create Release PR or Publish
        uses: changesets/action@v1
        with:
          version: <pm> run version
          publish: <pm> run release
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

Replace <pm> with pnpm, bun, npm, or yarn. Replace <install-command> with pnpm install --frozen-lockfile, bun install, etc.

Package manager setup snippets:

pnpm:

- uses: pnpm/action-setup@v4
- uses: actions/setup-node@v4
  with:
    node-version: 22
    cache: pnpm

bun:

- uses: oven-sh/setup-bun@v2
- uses: actions/setup-node@v4
  with:
    node-version: 22

npm/yarn:

- uses: actions/setup-node@v4
  with:
    node-version: 22
    cache: npm   # or: yarn

Token note: GITHUB_TOKEN is sufficient for most setups. If your repo has branch protection rules that require CI status checks on the "Version Packages" PR, you'll need a PAT with repo scope stored as a secret (e.g. RELEASE_TOKEN) and passed as GITHUB_TOKEN: ${{ secrets.RELEASE_TOKEN }} — this lets the action's commits trigger CI.

GitHub Actions — Option B (shared workflow)

Use this when you want all your repos to share one release pipeline definition. Changes to the shared workflow apply to all repos at once.

In the <user-or-org>/.github repo, create .github/workflows/release-changeset.yml:

name: release-changeset
on:
  workflow_call:
    inputs:
      node-version:
        type: string
        default: '22'
    outputs:
      published:
        description: 'Whether packages were published'
        value: ${{ jobs.release.outputs.published }}

concurrency: ${{ github.workflow }}-${{ github.ref }}

permissions:
  contents: write
  pull-requests: write
  id-token: write

jobs:
  release:
    runs-on: ubuntu-latest
    outputs:
      published: ${{ steps.changesets.outputs.published }}
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0
      # Add your standard setup steps here (package manager, node, install, build)
      - name: Create Release PR or Publish
        id: changesets
        uses: changesets/action@v1
        with:
          version: <pm> run version
          publish: <pm> run release
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

In each consuming repo, create .github/workflows/release.yml:

name: release
on:
  push:
    branches: [main]

jobs:
  release:
    uses: <user-or-org>/.github/.github/workflows/release-changeset.yml@main
    secrets: inherit

GitLab CI (.gitlab-ci.yml)

release:
  stage: release
  image: node:22
  only:
    - main
  script:
    - <install-command>
    - <build-command>     # remove if no build
    - <pm> run version
    - git config user.email "ci@bot" && git config user.name "CI Bot"
    - git add . && git commit -m "chore: version packages" || true
    - git push "https://oauth2:${GITLAB_TOKEN}@${CI_SERVER_HOST}/${CI_PROJECT_PATH}.git" HEAD:main || true
    - <pm> run release
  variables:
    NPM_TOKEN: $NPM_TOKEN

Secrets: add NPM_TOKEN and GITLAB_TOKEN (a project access token with write_repository scope) in Settings → CI/CD → Variables.

Note: changesets/action is GitHub-only. On GitLab you call changeset version + changeset publish directly and handle the git commit/push yourself. The "Version Packages" PR pattern is not available — version bump and publish happen in one CI run.

CircleCI (.circleci/config.yml)

version: 2.1

jobs:
  release:
    docker:
      - image: cimg/node:22.0
    steps:
      - checkout
      - run: <install-command>
      - run: <build-command>     # remove if no build
      - run: <pm> run version
      - run: git config user.email "ci@bot" && git config user.name "CI Bot"
      - run: git add . && git commit -m "chore: version packages" || true
      - run: git push || true
      - run: <pm> run release

workflows:
  release:
    jobs:
      - release:
          filters:
            branches:
              only: main

Secrets: add NPM_TOKEN in Project Settings → Environment Variables in the CircleCI UI.

Bitbucket Pipelines (bitbucket-pipelines.yml)

pipelines:
  branches:
    main:
      - step:
          name: Release
          image: node:22
          script:
            - <install-command>
            - <build-command>     # remove if no build
            - <pm> run version
            - git config user.email "ci@bot" && git config user.name "CI Bot"
            - git add . && git commit -m "chore: version packages" || true
            - git push || true
            - <pm> run release
          deployment: production

Secrets: add NPM_TOKEN in Repository settings → Repository variables in the Bitbucket UI.

Azure Pipelines (azure-pipelines.yml)

trigger:
  branches:
    include: [main]

pool:
  vmImage: ubuntu-latest

steps:
  - task: NodeTool@0
    inputs:
      versionSpec: '22'
  - script: <install-command>
    displayName: Install dependencies
  - script: <build-command>
    displayName: Build           # remove if no build
  - script: |
      <pm> run version
      git config user.email "ci@bot"
      git config user.name "CI Bot"
      git add . && git commit -m "chore: version packages" || true
      git push || true
      <pm> run release
    displayName: Version and publish
    env:
      NPM_TOKEN: $(NPM_TOKEN)

Secrets: add NPM_TOKEN as a pipeline variable (secret) in Azure DevOps → Pipelines → Edit → Variables.

Jenkins (Jenkinsfile)

pipeline {
  agent any
  triggers { pollSCM('H/5 * * * *') }
  stages {
    stage('Release') {
      when { branch 'main' }
      steps {
        sh '<install-command>'
        sh '<build-command>'   // remove if no build
        sh '<pm> run version'
        sh 'git config user.email "ci@bot" && git config user.name "CI Bot"'
        sh 'git add . && git commit -m "chore: version packages" || true'
        sh 'git push || true'
        withCredentials([string(credentialsId: 'NPM_TOKEN', variable: 'NPM_TOKEN')]) {
          sh '<pm> run release'
        }
      }
    }
  }
}

Secrets: add NPM_TOKEN via Manage Jenkins → Credentials as a secret text credential.

Travis CI (.travis.yml)

language: node_js
node_js: '22'
branches:
  only: [main]
install:
  - <install-command>
script:
  - <build-command>     # remove if no build
deploy:
  provider: script
  script: >-
    <pm> run version &&
    git config user.email "ci@bot" && git config user.name "CI Bot" &&
    (git add . && git commit -m "chore: version packages" || true) &&
    (git push || true) &&
    <pm> run release
  on:
    branch: main

Secrets: add NPM_TOKEN via Travis CI → Repository settings → Environment Variables.

Drone CI (.drone.yml)

kind: pipeline
type: docker
name: release

trigger:
  branch: [main]
  event: [push]

steps:
  - name: release
    image: node:22
    environment:
      NPM_TOKEN:
        from_secret: npm_token
    commands:
      - <install-command>
      - <build-command>     # remove if no build
      - <pm> run version
      - git config user.email "ci@bot" && git config user.name "CI Bot"
      - git add . && git commit -m "chore: version packages" || true
      - git push || true
      - <pm> run release

Secrets: add npm_token via Drone → Repository settings → Secrets.

Step 6 — Add secrets to the repository

Add the following secrets in your platform's secret/variable settings:

• NPM_TOKEN — an npm automation token (create at npmjs.com → Access Tokens → Generate New Token → Automation)
• RELEASE_TOKEN — optional PAT (GitHub only), needed if branch protection requires CI on the "Version Packages" PR

Step 7 — Verify

# Add a test changeset
npx changeset add --empty

# Check it was created
ls .changeset/

# Check the release workflow is valid (GitHub only)
gh workflow list

What the automated flow looks like

Once set up, the full cycle is:

1. Developer adds a changeset file to their PR (see add-changeset skill)
2. PR merges to main
3. CI runs changesets/action — detects new changesets, opens/updates a "Version Packages" PR (GitHub only; on other platforms, version bump and publish happen in one CI run)
4. When ready to release, merge the "Version Packages" PR
5. CI runs again — no pending changesets, so it runs release and publishes to npm

The "Version Packages" PR is fully managed by the action. Do not manually edit CHANGELOG.md or the version numbers it touches.
