Last Commit Info

This GitHub Action retrieves comprehensive information about the last commit in a repository. It can fetch commit details for the entire repository or for a specific file path, making it useful for various CI/CD workflows that need to access commit metadata.

Features

• Get the last commit SHA, message, and metadata
• Support for filtering by specific file path
• Retrieve both author and committer information
• Get API and HTML URLs for the commit
• Works with any repository (default: current repository)
• Uses GitHub CLI for reliable API access - It DOES NOT require checkout of the repository
