description	Pre-release review and changeset generation for npm packages using @changesets/cli. Use when: preparing a release, generating changelogs, pre-release checklist, version bump, writing release notes, reviewing README before publish. Triggers: "prepare release", "pre-release", "generate changelog", "write changesets", "release checklist".

pre-release — Release Readiness & Changeset Generation

A structured pre-release workflow that runs automated checks, generates user-facing changesets from git history, and optionally spawns fresh-eyes README reviewers.

When to Use

• Before any npm publish or version bump
• When you need to generate CHANGELOG entries from recent work
• Before merging a release PR
• Any time you want a release-readiness report

Prerequisites

The target project must have @changesets/cli initialized:

npm install --save-dev @changesets/cli @changesets/changelog-github
npx changeset init

See Changesets Setup for first-time configuration.

The Workflow

Step 1: Pre-Flight Checks

Run these checks against the project root. Report each as ✅ / ❌ / ⚠️:

#	Check	How
1	README.md exists with: purpose, install, usage, prerequisites, license	Read and verify sections
2	LICENSE file present and matches package.json license field	Compare files
3	No hardcoded credentials, API keys, or personal paths in tracked files	git grep -iE '(api.key|secret|password|token|/Users/|/home/|C:\\\\Users)' -- ':!*.lock' ':!node_modules'
4	No TODO/FIXME/HACK in shipped code	git grep -iE '(TODO|FIXME|HACK)' -- '*.ts' '*.js' '*.mjs' ':!node_modules' ':!*.test.*' ':!*.spec.*'
5	Tests pass	npm test (or project's test command)
6	Lint passes	npm run lint (if script exists)
7	Build succeeds	npm run build (if script exists)
8	Git working tree clean	git status --porcelain
9	On correct branch	git branch --show-current (should be main or release branch)
10	.gitignore covers: node_modules, dist, .env, editor config	Read .gitignore
11	package.json has required fields: name, version, description, license, repository	Read and verify
12	.changeset/config.json exists and is configured	Read and verify
13	GitHub Actions release workflow uses Trusted Publishers (OIDC), not NPM_TOKEN	Read .github/workflows/release.yml; verify id-token: write permission present and no NPM_TOKEN / NODE_AUTH_TOKEN secrets used
14	Trusted Publisher configured on npmjs.com for this package	Ask user to confirm (cannot be checked programmatically)
15	History scan clean (gitleaks + trufflehog)	gitleaks detect --source . --verbose AND trufflehog git file://. --since-commit=HEAD~0 --fail — both must pass with zero findings
16	Workflow security audit	Read all .github/workflows/*.yml — verify: least-privilege permissions: (job-level, not write-all), actions pinned by SHA (not tag), no pull_request_target with PR head checkout, no secret interpolation in echo/$GITHUB_OUTPUT/$GITHUB_ENV, no broad GITHUB_TOKEN perms, no env dumping in debug steps
17	Template-only values in examples	git grep -rE '(ghp_[A-Za-z0-9]{36}|npm_[A-Za-z0-9]{36}|sk-[A-Za-z0-9]{48}|AKIA[A-Z0-9]{16}|xox[bprs]-)' -- ':!node_modules' ':!*.lock' — must be zero; all example configs must use <REPLACE_ME> placeholders
18	No .local files tracked	git ls-files '*.local' '*.local.*' '.env.local' — must return empty
19	Redaction review for docs & screenshots	Scan README, docs/, and any images for: internal domains (*.internal, *.corp), tenant/account IDs, internal route patterns, environment naming conventions, unredacted screenshots
20	Skills discovery (if project ships skills)	Only if SKILL.md files exist: (a) .well-known/skills/index.json exists and lists every skill found by find . -name SKILL.md, (b) README lists every skill in a discoverable table, (c) package.json files includes .well-known/. Run npx skills add . --list and verify output matches expectations.

Blockers (must fix before release): checks 1-5, 8, 11-18, 20 (if applicable). Warnings (should fix): checks 6-7, 9-10, 19. Info: anything else notable.

Step 2: Generate Changesets

This is the core value — AI-written, user-facing release notes instead of mechanical commit scraping.

2a. Find the range

# Last release tag
LAST_TAG=$(git describe --tags --abbrev=0 2>/dev/null || echo "")

# If no tags, use first commit
if [ -z "$LAST_TAG" ]; then
  RANGE="$(git rev-list --max-parents=0 HEAD)..HEAD"
  echo "No previous tags found — covering entire history"
else
  RANGE="${LAST_TAG}..HEAD"
  echo "Changes since $LAST_TAG"
fi

2b. Gather the raw material

# Commits with files changed
git log $RANGE --pretty=format:'%h %s' --no-merges

# For more context on what changed
git log $RANGE --pretty=format:'### %h %s%n%b' --no-merges

# Files changed (to understand scope)
git diff --stat $LAST_TAG..HEAD 2>/dev/null || git diff --stat $(git rev-list --max-parents=0 HEAD)..HEAD

Also check for existing pending changesets — don't duplicate:

ls .changeset/*.md 2>/dev/null | grep -v README.md

If there are already changeset files, read them and account for what's already covered.

2c. Classify and write changesets

Group commits by impact and write changeset files. Each changeset is a markdown file in .changeset/:

File format (.changeset/<descriptive-name>.md):

---
"package-name": patch
---

Brief, user-facing description of what changed.

Semver classification:

Type	Bump	Examples
Breaking API changes	major	Removed function, changed signature, dropped Node version
New features, capabilities	minor	New command, new option, new API
Bug fixes, docs, internal	patch	Fix crash, update README, refactor internals

Writing guidelines:

• Write for users, not developers. "Added --verbose flag" not "refactored logger module"
• Group related commits into a single changeset when they're part of one logical change
• Use present tense: "Add", "Fix", "Remove", not "Added", "Fixed", "Removed"
• If a commit is purely internal (CI, refactor with no behavior change), it can be omitted or grouped under a generic "Internal improvements" patch
• One changeset per logical change, not per commit

Name the files descriptively using kebab-case: add-verbose-flag.md, fix-auth-crash.md, initial-release.md.

2d. For initial releases (no previous tags)

Write a single changeset covering the initial release:

---
"package-name": minor
---

Initial release.

- Feature 1: brief description
- Feature 2: brief description
- Feature 3: brief description

Use minor (0.1.0) for initial releases unless the project is already at 1.x.

Step 3: Fresh-Eyes README Review (Optional)

Load the run-agents skill. Use pi-subagents to spawn 2 parallel agents on different models to review the README as first-time users:

{ "tasks": [
    { "agent": "_arch-reviewer", "task": "Read the README.md in <project-path>. You are a developer who has NEVER seen this project. Can you answer: (1) What does it do? (2) How to install? (3) How to use? (4) Prerequisites? (5) Where to get help? For each: quote relevant text or say MISSING. Then list anything confusing or that assumes prior knowledge.", "model": "google/gemini-3-pro" },
    { "agent": "_arch-reviewer", "task": "Read the README.md in <project-path>. You are a developer who has NEVER seen this project. Can you answer: (1) What does it do? (2) How to install? (3) How to use? (4) Prerequisites? (5) Where to get help? For each: quote relevant text or say MISSING. Then list anything confusing or that assumes prior knowledge.", "model": "github-copilot/gpt-5.3" }
]}

Read both outputs and note any gaps.

Step 4: Report

Present the final report in this structure:

# Pre-Release Report: <package-name>

## Version: <current> → <proposed>
## Date: <today>

### Checklist
| # | Check | Status | Notes |
|---|-------|--------|-------|
| 1 | README | ✅/❌ | ... |
| ... |

### Changesets Generated
| File | Bump | Summary |
|------|------|---------|
| `add-feature-x.md` | minor | Add feature X |
| ... |

### README Review
(If Step 3 was run)
- **Gaps**: ...
- **Confusing**: ...

### Blockers (must fix)
1. ...

### Suggestions (can wait)
1. ...

### Ready to Release?
**YES** / **NO — N blockers remain**

Step 5: Commit (if approved)

If the user approves, commit the changeset files:

git add .changeset/*.md
git commit -m "chore: add changesets for next release" -m "Co-Authored-By: Pi <[e-mail]>"

Changesets Setup

For projects that don't have changesets yet. Run once:

1. Install

npm install --save-dev @changesets/cli @changesets/changelog-github
npx changeset init

2. Configure .changeset/config.json

{
  "$schema": "https://unpkg.com/@changesets/config@3.1.2/schema.json",
  "changelog": "@changesets/changelog-github",
  "commit": false,
  "fixed": [],
  "linked": [],
  "access": "public",
  "baseBranch": "main",
  "updateInternalDependencies": "patch",
  "ignore": []
}

Set "access": "public" for scoped packages (@scope/name). Set "baseBranch" to your default branch.

3. Add npm scripts to package.json

{
  "scripts": {
    "changeset": "changeset",
    "version-packages": "changeset version",
    "release": "changeset publish"
  }
}

4. GitHub Actions workflow (.github/workflows/release.yml)

name: Release

on:
  push:
    branches: [main]

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

permissions:
  contents: write
  pull-requests: write
  id-token: write  # Required for npm Trusted Publishing (OIDC)

jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 24  # npm >= 11.5.1 required for Trusted Publishing
          cache: npm
          registry-url: https://registry.npmjs.org

      - run: npm ci
      - run: npm run build
      - run: npm test

      - name: Create Release PR or Publish
        id: changesets
        uses: changesets/action@v1
        with:
          publish: npx changeset publish
          title: "chore: version packages"
          commit: "chore: version packages"
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

5. Configure Trusted Publishing (recommended — no tokens needed)

npm's Trusted Publishing uses OIDC to authenticate GitHub Actions with the npm registry. No NPM_TOKEN secret required.

1. Go to your package on npmjs.com → Settings → Trusted Publisher
2. Select GitHub Actions and configure:
   • Organization or user: your GitHub username
   • Repository: your repo name
   • Workflow filename: release.yml
3. That's it. The id-token: write permission in the workflow enables OIDC. Provenance attestations are generated automatically.

After verifying Trusted Publishing works, go to package Settings → Publishing access → "Require two-factor authentication and disallow tokens" for maximum security.

⚠️ NPM_TOKEN is deprecated: Do not use NPM_TOKEN secrets for publishing from GitHub Actions. Trusted Publishers (OIDC) is the only supported method. If you encounter an existing workflow using NPM_TOKEN, migrate it to Trusted Publishers. See: https://docs.npmjs.com/trusted-publishers

Tips

• Run this skill early and often, not just before release. The checklist catches issues faster when run during development.
• Edit generated changesets freely. They're just markdown files — tweak wording, merge entries, split large ones.
• One changeset per PR is a good rhythm. The pre-release skill can also be run to generate changesets for a single PR's worth of work.
• For monorepos, changesets handles multi-package versioning natively. List multiple packages in the frontmatter.
