Problem

changeset status maps changed files to packages. A pnpm catalog moves every dependency range to pnpm-workspace.yaml at the workspace root, which belongs to no package — so a catalog bump reads as "no package changed". But pnpm rewrites catalog: to the concrete range at pack time, so the published manifest of every consumer of that entry moves with no version bump behind it. The new range then sits unreleased until some unrelated PR happens to bump the package.

@gtbuchanan/eslint-config declares 26 catalog: entries in dependencies, so that is most of the exposure here.

This is narrower than "all dependency bumps". Under npm's default rangeStrategy, Renovate edits the catalog only when the new version falls outside the declared range — an in-range bump touches only pnpm-lock.yaml (confirmed on 32a1f4c, get-tsconfig 4.14.3). A catalog edit is therefore already a range-boundary crossing: exactly the consumer-visible set.

What this adds

gtb changeset check [--since <ref>] [--ignore <pkg>] diffs the catalog: / catalogs: blocks between the base ref and HEAD, maps each changed entry to the published packages declaring it in a runtime dependency field, and exits non-zero for any with no changeset covering them.

Both revisions are parsed and compared as maps, so reordering or reformatting pnpm-workspace.yaml reports nothing.

What keeps it quiet:

  • Only runtime fieldsdependencies, peerDependencies, optionalDependencies. Publishing strips devDependencies, so a vitest or faker bump never fires. Same field set and bundleDependencies exclusion as collectWorkspaceDependencies, for the same reasons.
  • Only published packages, and never one in the changesets config's ignore — it cannot be covered by a changeset, so demanding one would be a trap.
  • An empty changeset is not coverage. It is the documented way to say "no release", which is exactly the claim this gate exists to challenge.
  • Removed entries are skipped — orphaning one requires a package.json edit that changeset status already sees.

Structure

The core is pure and unit-tested: parseCatalogs, diffCatalogs, parseChangesetPackages, findUncoveredCatalogChanges, formatCatalogFinding in lib/catalog-gate.ts, plus collectCatalogDependencies in lib/discovery.ts mirroring the existing collectWorkspaceDependencies. Git access is injected at the command boundary, following gtb hk.

readBaseWorkspace deliberately separates "base predates the file" (→ empty, everything reads as added) from "git failed" (→ throws), via rev-parse --verifycat-file -eshow. Collapsing the two would turn a transient git error into a report that every catalog entry in the workspace just changed — the loudest possible false positive.

PackageCapabilities gains a catalogDependencies field.

Workflow

changeset-check.yml runs the gate beside the existing check, behind the same gtb-from-source input cd.yml uses (pr.yml sets it true). Consumers now need @gtbuchanan/cli, matching what cd.yml already requires.

Since the job installs for the gtb bin, the stock check moves from pnpm dlx to pnpm exec. The pnpm-resolve-pinned + pnpm dlx pairing existed only to skip the install, and it already required @changesets/cli to be a root devDependency — it read the version out of the lockfile — so pnpm exec adds no new constraint and resolves the same pinned version with one less step.

Verification

Exercised against this repo, not only fixtures:

Scenario Expected Result
Clean tree pass exit 0
eslint-plugin-unicorn ^73.0.0^74.0.0 gated exit 1, names @gtbuchanan/eslint-config
@faker-js/faker ^10^11 (devDependency only) not gated exit 0

The pure core was built test-first (red confirmed before implementing). 34 new tests; the full cli suite passes. Local pnpm build was stopped in favor of CI, which is faster here — lint:eslint and typecheck:ts were both run clean for @gtbuchanan/cli beforehand.

Not in scope

Base-ref resolution is left hardcoded to origin/main, matching the file's existing convention. That, and the fetch-depth: 0 that changeset status needs because it cannot run on a shallow clone, are tracked in #425.

🤖 Generated with Claude Code

`changeset status` maps changed files to packages, but a pnpm catalog
moves every dependency range to `pnpm-workspace.yaml` at the workspace
root, which belongs to no package. A catalog bump therefore reads as
"no package changed", while pnpm rewrites `catalog:` to the concrete
range at pack time — so every consumer's published manifest moves with
no version bump behind it, and the new range sits unreleased until some
unrelated PR happens to bump the package.

`gtb changeset check` diffs the catalog blocks between a base ref and
HEAD, maps each changed entry to the published packages declaring it in
a runtime dependency field, and fails when no changeset covers them.
Both revisions are compared as maps, so reformatting reports nothing.

What keeps it quiet: only runtime fields count, so publishing stripping
devDependencies means a test-only bump never fires; bundled deps,
private packages, and config `ignore` entries are excluded. An empty
changeset is not coverage — it is the documented way to say "no
release", which is the claim the gate exists to challenge.

`changeset-check.yml` runs it beside the existing gate, behind the same
`gtb-from-source` input `cd.yml` uses. The job now installs for the gtb
bin, so the stock check moves from `pnpm dlx` to `pnpm exec`: the
`pnpm-resolve-pinned` indirection existed only to skip the install, and
it already required `@changesets/cli` as a root devDependency to read
the version from the lockfile.

Base-ref resolution is left as-is; see #425.

Review Change Stack

📝 Walkthrough

Walkthrough

Adds catalog dependency analysis and the gtb changeset check command. The command detects uncovered catalog changes, supports ignores and Git base refs, and integrates with reusable CI workflows.

Changes

Catalog changeset gate

Layer / File(s) Summary
Catalog analysis and dependency discovery
packages/cli/src/lib/catalog-gate.ts, packages/cli/src/lib/discovery.ts, packages/cli/test/catalog-gate.test.ts, packages/cli/test/coverage-codecov-upload.test.ts, packages/cli/test/turbo-config.helpers.ts
Parses default and named catalogs, detects additions and range changes, discovers runtime catalog consumers, and identifies uncovered published packages. Tests cover parsing, diffing, exclusions, coverage, and formatting.
Changeset check command and orchestration
packages/cli/src/commands/root/changeset.ts, packages/cli/src/commands/index.ts, packages/cli/src/commands/root/index.ts, packages/cli/src/commands/root/names.ts, packages/cli/test/changeset-check.test.ts
Adds gtb changeset check with Git base resolution, workspace and changeset parsing, ignore handling, reporting, and exit codes. Registers and tests the command.
CI integration and gate documentation
.github/workflows/changeset-check.yml, .github/workflows/pr.yml, AGENTS.md, packages/cli/skills/gtb-build-pipeline/SKILL.md, .changeset/catalog-changeset-gate.md
Runs Changesets through workspace dependencies, adds the catalog gate, supports source-based CLI execution, and documents the workflow and command behavior.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 7b473

The changeset gate can currently misclassify a Git failure while reading the base workspace file as a missing file, producing false catalog-change failures across the workspace. This bounded correctness issue should be fixed before merge.

Codecov flagged the patch at 64% against an 80% target: the pure core
was tested but the glue that reads `.changeset`, the changesets config,
and the workspace file was not, leaving `changeset.ts` at 45%.

Adds tests that drive `runChangesetCheck` and `changesetCheckCommand`
against a scaffolded temp monorepo, covering changeset discovery on
disk, the config `ignore` list, the `--ignore` flag, and both exit
codes. A bare directory with none of the files the gate reads is
covered too, since a consumer without a catalog or a `.changeset`
directory must no-op rather than throw.

Also covers the catalog parser's empty-document and
`catalogs.default`-merge branches.

Only the citty wrapper is left uncovered, matching the other commands.

Learning: In the gtbuchanan/tooling repo, `.changeset/*.md` files should intentionally omit the Markdown H1 heading (MD041). Follow the changesets CLI convention: `frontmatter` followed by a blank line and then a plain summary text line. Do not prepend the summary with `# `, because the changesets CLI consumes that summary verbatim as the CHANGELOG entry; adding `# ` would introduce an unwanted stray H1 into the generated changelog. MD041 is not enforced by the repo’s `eslint-markdownlint` config for these files; any MD041 warnings for `.changeset/*.md` come from markdownlint-cli2 defaults rather than the repo’s own lint configuration.

Learning: When reviewing tests (e.g., in packages/**/test/**/*.test.ts), if the system-under-test explicitly branches on specific string-literal values (such as sort order, extension filters, or reserved filename exclusions like "PklProject"), require those branching inputs to be hardcoded literals in the test rather than generated via test-data builders. Do not recommend replacing these literals with builder patterns, because it would obscure what behavior is being exercised. Allow builder patterns only for incidental, domain-shaped data where the exact values do not affect the assertion logic (e.g., scoped package names or semver ranges used as opaque inputs).

Learning: In tests within **/{test,e2e,__tests__}/**/*.{test,spec}.{ts,tsx,js,jsx}, follow the AGENTS.md faker convention: direct `faker-js/faker` usage is allowed only for one-off primitives when the produced value’s shape is exactly what faker returns (e.g., `faker.git.commitSha()`, `faker.string.uuid()`). Use `gtbuchanan/test-utils/builders` only when there is a domain-shaped value worth centralizing (e.g., scoped package names, semver ranges, GitHub URLs). Do not wrap a native faker generator in a builder for a plain primitive (e.g., a raw commit SHA), since that adds indirection without centralizing any domain shape.

Learning: In the CLI package, keep deterministic string ordering by using the shared `localeComparer` comparator from `packages/cli/src/lib/sort.ts` (which pins locale via `left.localeCompare(right, 'en')`) instead of calling `string.localeCompare` inline. This prevents host/default-locale differences from changing generated outputs (e.g., task order in `turbo.json`). If adding new sorting logic in this package, route it through `localeComparer` to match existing behavior.

Learning: In this repository (gtbuchanan/tooling), GitHub Actions used in workflows are intentionally referenced by moving tags/branches (e.g., `actions/checkoutv*`, `actions/upload-artifactv*`, `actions/cachev*`, `actions/create-github-app-tokenv*`, and other third-party actions like `rharkor/caching-for-turbov*`), and should never be pinned to a commit SHA. There is no repo-wide SHA-pinning policy; therefore, do not flag these as “unpinned” or suggest SHA-pinning (zizmor’s default `unpinned-uses` rule does not apply here). For in-repo composite actions referenced by reusable workflows, the deliberate documented convention is to use `main` (e.g., `gtbuchanan/tooling/.github/actions/mise-setupmain`), matching how consumers reference the reusable workflows themselves (`.../.github/workflows/<name>main`). Do not change `main` references to SHAs to avoid hash bumps and the self-reference paradox.

Comment thread .github/workflows/changeset-check.yml Outdated
Comment thread packages/cli/src/commands/root/changeset.ts
`runChangesetCheck` passed `--cwd` to discovery and every file read but
not to `readBaseWorkspace`, and `execute` spawns without a `cwd`. So the
head workspace came from the target directory while the base revision
came from whatever directory the process happened to be in.

Pointing `--cwd` at another repository therefore either failed to
resolve the base ref or, worse, diffed two unrelated
`pnpm-workspace.yaml` files and reported every catalog entry as newly
added — the same false-positive class the surrounding comment claims
the design prevents.

`readBaseWorkspace` now takes the root and prefixes every invocation
with `git -C`, leaving the `CatalogGateDeps` contract unchanged. The
regression test asserts the prefix on every recorded call; it fails
against the previous implementation.

Also corrects the claim that both gates run from node_modules — with
`gtb-from-source` the catalog gate runs from workspace source, and gtb
needs node_modules either way for its own dependencies.

Learning: In CLI tests, capture generated fixture values in variables when the test asserts the same generated value after setup. Do not capture values that are only used as write-only fixture scaffolding with no corresponding assertion; use inline builder calls such as `build.*()` instead, as established in `packages/cli/test/tsconfig-single-package.test.ts`.

Distinguish a missing base file from a Git failure.

Line 148 maps every git cat-file -e failure to a missing pnpm-workspace.yaml. A corrupt or unreadable base object also fails this command. The gate then compares against '' and reports all current catalog entries as new instead of surfacing the Git error.

Use a command such as git ls-tree that returns an empty result for an absent path, and throw on its non-zero exit code. Add a test for a failing historical-file lookup.

Proposed fix
-  const exists = await git(['cat-file', '-e', target]);
-  if (exists.exitCode !== 0) {
+  const listed = await git([
+    'ls-tree',
+    '--name-only',
+    base,
+    '--',
+    workspaceFileName,
+  ]);
+  if (listed.exitCode !== 0) {
+    throw new Error(`git ls-tree ${base} failed: ${listed.stderr}`);
+  }
+  if (listed.stdout === '') {
     return '';
   }

the historical workspace-file lookup around git and the target path so an absent
path returns an empty result while any non-zero Git failure is propagated
instead of treated as missing; use a lookup such as git ls-tree and add a test
covering a failed historical-file lookup.
