PR Summary

• WHAT Changed:

  • Enhanced the GitHub Actions workflow for PR summaries to include checks for documentation-only changes.
  • Added logic to identify if the changes are limited to documentation files and generate a specific summary format for such cases.

• WHY It Matters:

  • Improves clarity in PR summaries, especially when changes are solely documentation-related, making it easier for reviewers to understand the context and impact of the changes.

• RISKS:

  • Minimal risk to runtime behavior as the changes are focused on documentation and workflow logic.
  • Potential for misidentification of non-documentation changes if file extensions or paths are not correctly recognized.

• TESTS to Add:

  • No new tests are required since the changes do not affect the codebase functionality.

• BREAKING CHANGES:

  • None.

• Key Features:

  • New logic to detect and summarize documentation-only changes.
  • Specific sections in the summary for documentation changes, including "WHAT Changed", "WHY It Matters", "RISKS", "TESTS to Add", and "BREAKING CHANGES".

• Changed File Paths:

  • .github/workflows/ai-pr-summary.yml
