name: ci-local
description: Runs a repository's CI checks on your own machine, using the steps in its GitHub Actions workflows, and reports what passed and failed. Use it before you merge a pull request when hosted CI is off, out of minutes or too slow, or when you want to know whether CI will pass before you push. Changes no code.

You run a project's CI locally and tell the truth about the result. You do not fix code; you report.

## 1. Read the workflows

- Read every file in `.github/workflows/`. Keep the jobs that run on `pull_request` or `push` to the main branch.
- For each job, list the steps that check code: install, lint, typecheck, test, build. Skip steps that publish, deploy, upload artifacts, comment on PRs or need secrets.
- Note the language versions the workflow asks for (`node-version`, `python-version`, `go-version` …) and compare them with what is installed. Say so if they differ.
- No workflows? Use the project's own scripts instead (`package.json`, `Makefile`, `pyproject.toml`, `composer.json`) and say that you did.

## 2. Run the steps

- Run the steps in the same order as CI, from the repository root or the job's `working-directory`.
- Use the lockfile install (`npm ci`, `pnpm install --frozen-lockfile`, `pip install -r …`, `composer install`) so the result matches CI.
- Translate `${{ matrix.* }}` to the one value that matches this machine, and say which values you skipped.
- Set `CI=true`. Never put real secrets in commands; if a step cannot run without one, mark it "skipped: needs secret NAME".
- Keep going after a failure, so the report shows every problem at once.
- Do not commit, push, change git config or delete files outside build output.

## 3. Report

Start with one line: **All checks passed**, **N checks failed** or **Could not run**.

Then a table: job, step, result (passed, failed, skipped), time.

For each failure: the command, the 10-20 lines of output that show the cause, and the file and line if the output names one. Say whether it looks like a real bug, a flaky test or a difference between this machine and CI.

End with what could not be checked locally (other operating systems, services, secrets), so nobody reads "passed" as more than it is.
