Adds a shared WordPress.org Plugin Check workflow. A plugin repo adds one short caller file and gets the same check on every pull request, with a result comment, instead of keeping its own copy of the setup.

Why

WordPress.org runs Plugin Check on every plugin it reviews. A problem found at review time costs a release. Found on a pull request, it costs one fix.

• One setup for every plugin. The build, the check, the comment and the baseline logic live here once. A fix or an improvement reaches every plugin that uses a tag.
• Works for plugins that are not clean yet. A ratchet mode compares the error count of each rule with an earlier run of the target branch. A pull request fails only when a rule gets worse, so a plugin with known problems can turn the check on today and fix the old ones over time. When it reaches zero errors, mode: strict fails on any error.
• Checks what ships. It builds the release zip with pup and checks that, so tests, dotfiles and other dev-only files cannot cause false results.
• Safe by default. The job that runs the third-party action has a read-only token. A separate job writes the comment.

What changed

• .github/workflows/plugin-check.yml is the reusable workflow, with three jobs:
  • start posts an "in progress" comment.
  • check builds the plugin and runs wordpress/plugin-check-action.
  • report compares the results with the baseline and writes the pull request comment.
• .github/actions/plugin-check-report/ is a composite action with ratchet.sh and fetch-baseline.sh, so callers do not need the scripts. It has its own README.
• templates/workflows/plugin-check.yml is a caller to copy into a plugin repo.
• tests/actions/plugin-check-report/ has the tests and sample result files for both scripts.
• test.yml gets a lint job: actionlint 1.7.12 on the workflows and templates, and shellcheck on the action scripts. The queue key is ignored because actionlint 1.7.12 does not know it yet (release-tags.yml uses it).

How a repo uses it

jobs:
  plugin-check:
    permissions:
      actions: read
      contents: read
      issues: write
      pull-requests: write
    uses: stellarwp/plugin-toolbox/.github/workflows/plugin-check.yml@main
    with:
      plugin-slug: my-plugin

A called workflow cannot get more than the caller gives it, so the caller must grant those permissions. The template shows the full file.

Inputs: plugin-slug (required), main-file, build-command, runs-on, php-version, exclude-checks, cache-paths, mode, submodules. Optional secrets: composer-token, package-token.

• Build: by default it runs the pup flow (composer pup build, pup package, unzip), so .puprc is the one place that says how the plugin is built. build-command replaces it for repos that do not use pup. A custom command is a second place that defines the build, so prefer .puprc when the repo has one.
• Mode: ratchet (default) or strict. It is not called strict alone because wordpress/plugin-check-action already has an input with that name.
• Baseline: the counts of an earlier run of the target branch, found through its plugin-check-report artifact. Nothing is committed. A pull request uses the run for its base commit and waits for it if it is still going. A push uses the run before it. fetch-baseline.sh --workflow finds the caller's workflow file, because inside a called workflow GITHUB_WORKFLOW_REF names the caller's file.
• Comment: one sticky comment per pull request. Its marker is derived from the repository, so two plugins never share one.

After this merges

Nothing else to do here. This repository publishes no releases, so callers use @main. That means every merge to main reaches every repo that uses it on the next run, so changes to this workflow and action need the same care as a release.

The workflow calls its own action with uses: $/.github/actions/plugin-check-report. GitHub added this self-repository reference in July 2026: $/ is this repository at the exact commit that runs the workflow, with no ref and no checkout. So the action always comes from the same commit as the workflow, whichever ref the caller used. A caller can test a change from a branch name, or pin the workflow to a commit, and the action follows. It needs a runner of version 2.336.0 or newer: the job that uses it runs on ubuntu-latest, which has it. The newest actionlint (1.7.12) does not know the syntax yet, so the lint job ignores that one error, only for a $/ reference.

Plugin repos adopt it with their own pull requests.

Test plan

• node --test: 230 tests pass, including the new ones.
• actionlint and shellcheck pass.
• GITHUB_WORKFLOW_REF names the caller's file in a called workflow, on push and pull_request.
• Full run in a fork of a real plugin repository: the first run has no baseline and passes with a warning.
• A run on the target branch creates the baseline.
• A pull request that adds an unescaped output fails, names the rules that went up, and links to the baseline run.
• The same pull request with the change removed passes with ±0.
• The same shared workflow, called from a fork with the PR branch as its ref, loads its action through $/ from the same commit and passes.

Not checked

• A pull request from a fork into the real repository, where the token is read-only. Needs a second account.
• Callers must update a required status check: a job in a reusable workflow reports as <caller job id> / <job name>, for example plugin-check / Plugin Check.
• Baselines expire with their artifacts (90 days by default). A repo with no pushes for that long gets "no baseline" and a pass with a warning.
• build-command and submodules are covered by the validation step and the docs, not by a full run.

Not in this PR

zip-url (reuse an existing zip instead of building). Add it when a repo needs it.

To run the scripts on your machine, see the action's README.

Summary by CodeRabbit

• New Features
  • Added a reusable workflow to build plugins, run WordPress Plugin Check, compare results with a previous run, and report findings.
  • Configure ratchet mode to fail when errors increase, or strict mode to fail whenever errors are found. Increased warnings are reported without failing ratchet checks.
  • Pull requests in the same repository receive status and result comments, with links to available reports.
  • Added a workflow template to help configure plugin checks.
• Bug Fixes
  • Pull-request checks can fall back to a recent target-branch run when an exact baseline is unavailable.
• Documentation
  • Added setup, configuration, and usage guidance for the workflow and reporting features.

Walkthrough

This pull request adds a reusable GitHub Actions workflow that builds and checks a plugin, selects a baseline, compares Plugin Check rule counts, and reports results. It also adds a caller template, tests, fixtures, documentation, and lint checks.

Changes: Plugin Check reporting flow

Layer / File(s)	Summary
Compare results and produce reports .github/actions/plugin-check-report/ratchet.sh, tests/actions/plugin-check-report/ratchet.test.js, tests/actions/plugin-check-report/fixtures/*	The script validates Plugin Check output, counts errors and warnings by rule, compares counts with a baseline, and writes a Markdown summary. Tests and fixtures cover ratchet and strict modes, baseline updates, and report output.
Select baselines and wire the report action .github/actions/plugin-check-report/action.yml, .github/actions/plugin-check-report/fetch-baseline.sh, tests/actions/plugin-check-report/fetch-baseline.test.js, .gitignore	The action uploads results and a generated baseline, selects a prior run, and passes comparison inputs to the report script. Tests cover run selection, artifact handling, and lookup failures.
Build, check, and report through the reusable workflow .github/workflows/plugin-check.yml, templates/workflows/plugin-check.yml, .github/workflows/test.yml, .github/actions/plugin-check-report/README.md	The reusable workflow defines inputs and secrets, builds and validates the plugin, runs Plugin Check, and reports results. The template calls the workflow. Lint checks cover workflow YAML and action scripts. The README documents setup, inputs, baseline behavior, and local use.

Cap the polling sleep at the remaining --wait time.

110-130: Minor · Stability & Availability · Quick win

Cap the polling sleep at the remaining --wait time.

When baseline-wait is set below 30 seconds and the base-commit run is still in progress, fetch-baseline.sh reaches sleep 30 after the deadline check. The pull request's Get the baseline step can therefore wait about 30 seconds instead of the documented value.

Suggested fix

Update the polling loop in fetch-baseline.sh so its sleep never exceeds the time
