PRobe – AI-powered code review companion integrated into GitHub pull requests

Summary: PRobe is a free, open-source AI tool embedded in GitHub pull requests that enables interactive code review by allowing users to chat with the PR, ask questions about specific files or lines, and submit review comments or full reviews directly within the interface.

What it does

PRobe detects the tech stack in pull request diffs and loads relevant open-source skill files to provide context-aware AI assistance tailored to the codebase. Users can query the AI about changes, probe specific code sections, and post review comments or complete reviews without leaving GitHub.

Who it's for

It is designed for developers and reviewers who handle large or complex pull requests and need contextual, human-like AI support to efficiently understand and evaluate code changes.

Why it matters

PRobe addresses the challenge of reviewing increasing volumes of AI-generated and complex code by providing AI assistance that complements human judgment, helping reviewers focus on nuanced understanding rather than just syntax or common errors.
