Autoship

Drive an npm release end to end: changeset, fix loop, push, CI watch, Version Packages PR merge, publish watch, npm verification.

• IS: the full release pipeline for an existing changesets-based npm package, from writing the changeset file to confirming the new version on the registry, plus diagnosing why a release run did not version or publish.
• IS NOT: opening a feature PR (use pr-creator), monitoring a feature PR for reviews, conflicts, or CI (use pr-babysitter), general build or type fixes outside a release flow, or scaffolding a new package (use scaffold-cli, which hands off to autoship for the first release).

The Release Loop

One workflow, two successive runs. Misreading it as two workflows causes most autoship mistakes.

1. Push a commit containing a pending .changeset/*.md file to the default branch.
2. The release workflow runs: changesets/action sees pending changesets, runs changeset version in CI, and opens or updates a PR on branch changeset-release/<default-branch> (title "Version Packages", suffixed "(next)" in pre mode) carrying the package.json bump and CHANGELOG.md entry.
3. Merge that PR once every check is green.
4. The same workflow runs again. With no pending changesets left, the action runs its publish script (changeset publish), which publishes to npm and, by default, pushes the git tag and creates a GitHub release.

The local job ends at "push the changeset file". CI owns versioning and publishing.

The action has two live majors with different input names: @v1 takes publish:, @v2 takes publish-script:. Read the uses: line before diagnosing a run that versioned but never published.

Safety Tiers

Invoking autoship is standing consent for the full release flow. Do not pause mid-flow to re-confirm; gate risky steps on objective preconditions instead.

• Green (execute directly): reads: CI and PR state, npm view, pending changesets, package.json scripts, git history and status.
• Yellow (announce in one line, then execute): writing changeset files, running lint/type/test/format fixers, git add/commit/push, starting watches, and merging the Version Packages PR once its identity is confirmed and every check passes.
• Red (explicit confirmation required): force-pushes, history rewrites, repository settings changes, any destructive git operation.

Workflow

Copy this checklist to track progress:

Autoship progress:
- [ ] Step 1: Create changeset (default patch)
- [ ] Step 2: Fix lint, types, tests, format
- [ ] Step 3: Commit and push the changeset
- [ ] Step 4a: Watch CI on the pushed commit
- [ ] Step 4b: Find and merge the Version Packages PR
- [ ] Step 5: Watch the publish run, verify on npm

Step 1: Create changeset (default patch)

• Load references/changeset-and-commit.md.
• Inspect pending changesets and their package coverage. Reuse those covering the requested release; add one only for uncovered changes. Ask only if unrelated pending releases make the publish scope ambiguous.
• Default to patch; minor or major only on explicit user instruction.
• Write the file directly (the interactive prompt needs a TTY); the summary is user-facing changelog text inferred from git log --oneline -10.
• pnpm changeset status validates the file: a misspelled package name fails here instead of in CI.

Step 2: Fix lint, types, tests, format

• Discover commands from package.json scripts (check, lint, typecheck, test, format, fix); in non-Node repos check Makefile, Cargo.toml, pyproject.toml, go.mod.
• Run lint, typecheck, test, format. After any code change, re-run from the first gate: a type fix routinely breaks lint, and a lint autofix can break a test.
• Scope auto-fixers to changed files where supported, then check git status: broad fix/format scripts reformat files outside the change (MDX is a frequent casualty). Undo only fixer changes introduced by this run, preserving pre-existing edits in the same files.
• Cap the loop at 5 fix iterations per gate, reporting the remaining error count each pass; then stop and report the gate, remaining error count, and last error output.

Step 3: Commit and push the changeset

• Stage the changeset file and in-scope fixes by explicit path; sweep git status --porcelain for hook artifacts (a root schema.gql is a known one) before committing.
• Commit (chore: add <type> changeset for <package>) and push.
• The pushed commit must still contain .changeset/*.md (first Gotcha).

Step 4a: Watch CI on the pushed commit

• Load references/ci-polling.md.
• Start the commit watch on the pushed SHA. It emits a line per state change and one TERMINAL: line when every run for that commit (CI and the release workflow) completes. An idle first poll is normal; runs take time to queue.
• On failure, classify from gh run view <id> --log-failed: flaky or infra gets gh run rerun <id> --failed (max 3); a real failure gets a fix, commit, push, and a fresh watch on the new SHA.

Step 4b: Find and merge the Version Packages PR

• Load references/version-pr-and-publish.md.
• Find the open PR whose head is changeset-release/<default-branch>. If absent, run the PR-wait watch (10-minute cap).
• Merge only when all three hold:
  • Head branch is changeset-release/<default-branch> (title normally "Version Packages", but pr-title can rename it). Never merge any other PR.
  • gh pr checks <n> --json name,bucket reports bucket: pass for every check.
  • gh pr view <n> --json mergeable reports MERGEABLE (on UNKNOWN, wait and re-query).
• Announce ("Merging Version Packages PR #N: <package>@<version>"), then gh pr merge <n> --squash --delete-branch, or the merge method the repo allows. Any failed precondition: stop and report, never merge.

Step 5: Watch the publish run, verify on npm

• Merging triggers the same workflow again; with no pending changesets it publishes.
• Take the merge SHA (gh pr view <n> --json mergeCommit --jq .mergeCommit.oid) and run the commit watch on it.
• On failure: read the log, match it against the publish failure table in references/version-pr-and-publish.md, report, and stop. Publish failures are never retried blind; every cause on that table needs a config or settings change.
• On success: npm view <package>@<version> version must print the merged version, and npm view <package> dist-tags must show latest pointing at it (unless pre mode). Stop remaining watches and report both outputs; they are the completion evidence.

Failure Recovery

Stop and report on a gate still failing after 5 iterations or any failed merge precondition; never override failing checks or resolve conflicts in the bot PR. Diagnosis lives with each stage: CI and Changeset Status failures in references/ci-polling.md, a missing Version Packages PR and publish failures in references/version-pr-and-publish.md.

Gotchas

• Never run pnpm changeset version locally. It consumes .changeset/*.md, so the pushed commit has no pending changeset, "Changeset Status" fails, and no Version Packages PR opens. Recovery is reverting the bump, not rerunning CI.
• Never run pnpm publish or npm publish directly. It bypasses changesets, skips the changelog and tag, and leaves the Version Packages PR describing an already-shipped version, which then fails with "You cannot publish over the previously published versions".
• Never hand-edit CHANGELOG.md or the package.json version. CI generates both in the Version Packages PR; local edits make the bot PR CONFLICTING.
• changesets/action@v2 renamed every input (publish to publish-script, version to version-script, title to pr-title, commit to commit-message, branch to pr-base-branch). The old names are ignored with only a warning, so a @v2 workflow still using publish: opens the Version PR and then completes green without publishing anything.
• setup-node with node-version: 22 ships npm 10.9.x. Trusted publishing needs npm 11.5.1 or later, so changeset publish fails ENEEDAUTH even with id-token: write set (pnpm hands the upload to the npm CLI on PATH). Use Node 24 or add npm install -g npm@latest before publishing.
• A workflow authenticating with an NPM_TOKEN secret that holds a classic token fails ENEEDAUTH: npm revoked every classic token on 9 December 2025. Move to trusted publishing rather than minting a new token; write-capable granular tokens expire within 90 days.
• npm does not validate a trusted publisher when you save it. A workflow filename that differs from .github/workflows/<file>.yml by case or extension surfaces only at publish time, as ENEEDAUTH.
• New personal repos block Actions from opening PRs. The release run fails with "GitHub Actions is not permitted to create or approve pull requests" and no Version PR appears. Fix: Settings, Actions, General, "Allow GitHub Actions to create and approve pull requests" (an org-level setting can override it). Red tier: report it, do not change settings unasked.
• gh pr list --json headBranch and gh pr checks --json conclusion are invalid fields and error. Use headRefName and bucket.
• The Monitor tool's default timeout_ms is 300000 (5 minutes). A CI run that outlasts it kills the watch with a timeout that looks like silence. Pass timeout_ms: 3600000 for CI watches.
• Poll every 30 seconds or slower. Faster loops burn the GitHub API rate limit (gh api rate_limit --jq .resources.core.remaining) and stall the flow mid-release.
• git add -A commits pre-commit-hook artifacts and fixer churn into the release commit. Stage explicit paths.
• major without explicit instruction signals breaking changes to every consumer. Default to patch.

• scaffold-cli: scaffolds a new TypeScript package with changesets and OIDC publishing, then hands off to autoship for its first release.
• pr-creator: opens feature PRs. Autoship merges only the bot-opened Version Packages PR.
• pr-babysitter: watches feature PRs (reviews, conflicts, CI). Autoship watches release CI only; never babysit a Version Packages PR autoship is driving.
