Why

#156 bumped changesets/action from v1 to v2 inside the routine weekly actions Dependabot group. It showed green and broke the release on main; #167 reverted it by pinning the action back to v1.

It was green because release.yml is triggered only by push: main. No pull request can run it, so a change to that file gets a tick from checks that never touched it.

Two independent things were broken, and PR CI could see neither:

  1. CLI major. v2 dropped Changesets v2 support and hard-errors when it finds a v2 CLI (changesets/action#699). The repo pinned @changesets/cli@^2.31.0.
  2. Input names. v2 renamed every input this step passes (versionversion-script, titlepr-title, commitcommit-message) and stopped reading the GITHUB_TOKEN environment variable. Unknown with: keys are silently dropped by GitHub Actions rather than rejected — so even without (1), the step would have run changeset version under a default "Version Packages" title instead of pnpm version-packages, and looked fine doing it.

Since the action and the CLI only move as a pair, this takes both majors rather than staying on v1.

What changed

The upgrade

  • @changesets/cli^3.0.1, @changesets/changelog-github^1.0.0, and .changeset/config.json's $schema@changesets/config@4.0.0.
  • release.yml moves to changesets/action@v2 with the renamed inputs and no env: block. github-token already defaults to the workflow token, and v2 warns (rather than fails) if a conflicting GITHUB_TOKEN is also set.

The guards

  • scripts/check-release-toolchain.mjs — asserts the action major and the CLI major agree, and that every with: key is a real input of that major. It runs as a new release-toolchain job in Workflow Lint (no dependency install: the script reads package.json and release.yml as text and imports nothing outside node:*), and as pnpm lint:release-toolchain locally. The supported majors are a hardcoded table rather than a fetch of the action's own action.yml, deliberately — the gate should fail on our mistakes, not on upstream retagging a moving major or on the network. Taking a new major means adding a row, and the check fails loudly on an unrecognised one rather than assuming it is fine.
  • dependabot.yml — the actions group is restricted to minor/patch, so action majors arrive as individual PRs with their own release notes and their own review. Same rationale already documented for the npm groups, plus one specific to this ecosystem: an action major is the single kind of bump this repository's CI is structurally unable to test.

Reviewer notes

  • Behaviour change worth knowing: Changesets v3 makes changeset version exit 1 when there is nothing to release, instead of exiting 0 having done nothing. This only bites when running it by hand — the action checks for pending changesets first and skips the version script when there are none. Noted in RELEASE.md.
  • GITHUB_TOKEN for changelog-github: removing the env: block does not break PR/author links. v2's runVersion injects GITHUB_TOKEN: github.getToken() into the version script's environment (src/run.ts), which is what @changesets/changelog-github reads.
  • Publishing is unaffected. Per RELEASE.md, CI never publishes, so v2 dropping its NPM_TOKEN/.npmrc handling costs nothing here.
  • Left alone, flagging it: registry-url: 'https://registry.npmjs.org' in the release job's setup-node. It writes an .npmrc expecting a NODE_AUTH_TOKEN that is deliberately never set, so it is inert — but now that v2 has dropped its own npm-auth handling it reads as though CI publishes, which RELEASE.md says it must not. Happy to drop it if reviewers agree.
  • No changeset file: this is repository tooling only, with no user-facing package change.

Verification

  • Ran pnpm version-packages for real against the v3 CLI: correct bumps (@spatialdata/* 0.8.0 → 0.9.0, zarrextra 0.4.0 → 0.5.0) and properly linked changelog entries. Reverted afterwards.
  • pnpm install --frozen-lockfile clean.
  • actionlint 1.7.12 (the pinned CI version, via docker) passes on all workflows.
  • Exercised all four failure modes of the new check — v1 inputs under a v2 action, a v2 action against a v2 CLI (the Bump changesets/action from 1 to 2 in the actions group across 1 directory #156 scenario), a v1 action against the now-v3 CLI, and an unrecognised v3 action. Each fails with a file:line and an explanation; the branch as it stands passes.

…iring

#156 bumped changesets/action from v1 to v2 inside the routine weekly
`actions` Dependabot group. It was green — release.yml is triggered only by
`push: main`, so no pull request can exercise it — and broke the release on
main, which #167 reverted by pinning the action back to v1.

The action and the CLI are a matched pair, so take both majors together:

- `@changesets/cli` -> ^3.0.1 and `@changesets/changelog-github` -> ^1.0.0.
  changesets/action v2 dropped Changesets v2 support and hard-errors on it
  (changesets/action#699). Config `$schema` moved to @changesets/config@4.0.0.
- release.yml migrates to the v2 input names (`version` -> `version-script`,
  `title` -> `pr-title`, `commit` -> `commit-message`) and drops the
  `GITHUB_TOKEN` env block; `github-token` already defaults to the workflow
  token, and v2's `runVersion` still injects GITHUB_TOKEN into the version
  script so changelog-github keeps resolving PR and author links.

Both halves of the breakage are now checked at pull-request time:

- scripts/check-release-toolchain.mjs asserts the action major and the CLI
  major agree, and that every `with:` key is a real input of that major.
  Unknown inputs are silently dropped by GitHub Actions rather than failing,
  so a mis-migrated step would have run `changeset version` under a default
  PR title instead of `pnpm version-packages`. It runs as a `release-toolchain`
  job in Workflow Lint, which needs no dependency install, and as
  `pnpm lint:release-toolchain` locally.
- The Dependabot `actions` group is restricted to minor/patch, so action
  majors arrive as individually reviewable PRs. Same rationale already
  documented for the npm groups, plus the ecosystem-specific one: an action
  major is the bump this CI is structurally unable to test.

Verified by running `pnpm version-packages` against the v3 CLI (correct bumps
and linked changelog entries, reverted afterwards), `pnpm install
--frozen-lockfile`, actionlint 1.7.12, and all four failure modes of the new
check.

Layer / File(s) Summary
Upgrade the Changesets toolchain
.changeset/config.json, package.json, .github/workflows/release.yml, .github/dependabot.yml
The repository updates the Changesets schema and dependencies, uses changesets/action@v2 inputs, and groups only minor and patch action updates.
Add release-toolchain validation
scripts/check-release-toolchain.mjs, package.json
The new checker validates the action major, action inputs, v2 token usage, and matching Changesets CLI major. The package script exposes the check.
Document and run the validation checkpoint
.github/workflows/workflow-lint.yml, RELEASE.md
The workflow-lint workflow runs the checker with Node.js 24.14.1. Release documentation describes Changesets v3 behavior, version coupling, workflow limitations, and future action-major updates.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to a76f7

This PR upgrades the release tooling and adds a guard to keep the action and CLI versions paired. The current configuration is merge-ready with no actionable merge-blocking risk; a small follow-up may harden the guard to accept quoted or SHA-pinned action references.

85-87: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Accept quoted and SHA-pinned refs when parsing the action version.

Line 86 captures the ref with \S+, and line 87 requires it to start with v<digits>. Two valid forms break that:

  • uses: 'changesets/action@v2' yields the ref v2', which still parses, but uses: "changesets/action@v2" after a leading quote change or uses: 'changesets/action@v2' with the opening quote inside the match produces a quoted token.
  • A commit-SHA pin with a trailing # v2.0.0 comment produces a ref that matches no known major.

Both cases fail the check even though the workflow is correct. Strip surrounding quotes, and read a trailing # vN comment when the ref is a SHA.

♻️ Proposed hardening
-const usesLine = lines[usesIndex];
-const ref = usesLine.match(/changesets\/action@(\S+)/)[1];
-const actionMajor = ref.match(/^v(\d+)/)?.[1];
+const usesLine = lines[usesIndex];
+const ref = usesLine.match(/changesets\/action@([^\s'"#]+)/)[1];
+// A SHA pin carries its major in a trailing `# v2.0.0` comment.
+const actionMajor =
+  ref.match(/^v(\d+)/)?.[1] ?? usesLine.match(/#\s*v(\d+)/)?.[1];
