A GitHub Actions–friendly tool that extracts code changes from Python pull requests and sends them to the auto-cepu API for LLM-powered automated code review.

This project is intended to run automatically inside CI (GitHub Actions) and is configured entirely via environment variables (.env), with no CLI arguments.

• Parse GitHub PR diffs to extract added/deleted Python code and corresponding full function definitions.
• Send extracted code sections to the auto-cepu API for analysis.
• Designed to run unattended in GitHub Actions.
• No manual arguments — fully configured via .env.

1. GitHub Actions triggers this script on pull request events.
2. It reads PR context and credentials from environment variables.
3. Fetches the PR diff from the GitHub API.
4. Extracts only the changed Python code (added/deleted lines along with their complete function definitions).
5. Sends the extracted code to your auto-cepu API endpoint.
6. auto-cepu responds with LLM-based review feedback (issues, suggestions, severity ratings, duplication analysis, etc.).
7. The analyzer automatically posts the review feedback as a reply to the pull request.

Before using this tool, make sure:

• Your project uses Python and GitHub Actions.
• You have an auto-cepu instance running and accessible.
