| # Commit Message Check | |
| # -------------------------------------------------------------------- | |
| # Checks the commit messages for a pull request to ensure they follow | |
| # the project's guidelines. This is not a required check and will not | |
| # block the PR from being merged. It provides suggestions for improving | |
| # commit messages. | |
| # | |
| # The main checks include: | |
| # * Title length (recommended: 50 characters or less) | |
| # * Title capitalization (should start with an uppercase letter) | |
| # * Body presence (should not be empty) | |
| # * Body line length (recommended: 72 characters or less) | |
