.github/workflows/pull-request-check.yml:17

• The steps list is mis-indented: - uses: ... is aligned with steps: instead of being nested under it. This makes the workflow YAML invalid and the job won’t run. Indent the step entries under steps: (e.g., steps: followed by - ...).
  .github/workflows/pull-request-check.yml:6
• This workflow is configured to run only for PRs targeting master, but the repository context/diff indicates the default branch is main (the previous config targeted main). As written, the workflow won’t trigger for PRs into main. Update the target branch (or remove the branch filter if you want it for all PRs).

This issue also appears in the following locations of the same file:

• line 14
• line 30
  .github/workflows/pull-request-check.yml:34

• pre-commit run --from-ref origin/master --to-ref HEAD hard-codes the base branch name. This will fail when the PR base branch isn’t master (e.g., main) and is also brittle for repos that rename default branches. Use the PR’s actual base ref/SHA (e.g., ${{ github.base_ref }} / ${{ github.event.pull_request.base.sha }}) instead of a fixed origin/master.
