PR Guard – GitHub Action verifying PR author’s understanding of changes

Summary: PR Guard is a GitHub Action that uses an LLM to generate three questions about a pull request’s diff, requiring the author to answer them to verify their understanding. It blocks the PR if answers indicate insufficient comprehension, promoting responsible code submissions.

What it does

It creates focused questions about the code changes and evaluates the author’s answers to determine if they understand the submitted code. Passing results in a green check; failing blocks the PR with explanations.

Who it's for

Developers and teams seeking to ensure PR authors comprehend their code changes, especially when AI-generated code is involved.

Why it matters

It addresses the risk of submitting code without understanding by encouraging authors to reflect on their changes before merging.
