💡 Result:

The term "commit-check" in a GitHub Actions workflow typically refers to the use of the Commit Check tool [1][2], a policy engine used to validate Git commit metadata such as commit messages, branch names, and author information [1][3][4]. While users may name their workflow files anything (e.g., pr-labeler.yml) [5], the specific action provided by the Commit Check project is commonly implemented in a dedicated workflow file like.github/workflows/commit-check.yml [3][6]. To integrate Commit Check into your workflow, you can add the following step to your GitHub Actions file [3][4]: - uses: commit-check/commit-check-action@v2 with: message: true branch: true # Optional configurations author-name: false author-email: false job-summary: true pr-comments: ${{ github.event_name == 'pull_request' }} Key requirements for this action include: 1. Using actions/checkout@v5 with fetch-depth: 0 to ensure the full history is available for validation [3][4][6]. 2. Optionally providing a cchk.toml file in your repository root to customize policies [2][6]. If you are encountering a workflow named pr-labeler.yml that includes a commit check, it is likely a custom implementation where the developer has combined automated PR labeling with a commit validation step (often using actions/github-script or custom bash scripts) to enforce project standards [7][8][9]. Unlike the dedicated Commit Check action, these custom implementations often use regex patterns or API calls to validate commit titles directly within the PR workflow [7][8].

💡 Result:

The file path.github/workflows/pr-labeler.yml is a common convention for a GitHub Actions workflow file designed to automatically label pull requests. While the specific file name is user-defined, it typically leverages the official actions/labeler GitHub Action to categorize pull requests based on the files they modify. To implement this functionality, you generally need two components: 1. A workflow file (e.g.,.github/workflows/pr-labeler.yml) that triggers on pull request events. 2. A configuration file (often located at.github/labeler.yml) that defines the rules for which files should trigger which labels. Example configuration for.github/workflows/pr-labeler.yml: name: Pull Request Labeler on: pull_request_target: types: [opened, synchronize, reopened] jobs: label: runs-on: ubuntu-latest permissions: contents: read pull-requests: write steps: - uses: actions/labeler@v5 with: repo-token: ${{ secrets.GITHUB_TOKEN }} The corresponding.github/labeler.yml file would map patterns to labels, such as: documentation: - docs/ - README.md frontend: - src/ui/ The provided search results did not contain specific implementation details for this file path within the referenced repositories.
