PRobe

What is PRobe?

PRobe is an AI-powered Chrome extension for reviewing GitHub Pull Requests. It helps you ask questions about a PR, drill into the code and files involved, and post review comments back in the GitHub PR workflow.

The core purpose of PRobe is to make it easier to understand changes in a PR by providing an interactive chat interface connected to the pull request context.

Key Features

• Chat with a specific GitHub Pull Request: Ask questions in natural language while staying grounded in the PR you’re reviewing.
• Drill into PR files and details: Use the extension to explore the code/content of the pull request as part of your review.
• Post comments to the PR: Turn your questions and observations into comments on the pull request thread.
• GitHub PR review workflow: Designed to operate directly inside the GitHub pull request review process rather than as a separate tool.

How to Use PRobe

1. Install the PRobe Chrome extension.
2. Open the GitHub page for the pull request you want to review.
3. Use PRobe’s chat interface to ask questions about the PR’s changes and relevant files.
4. When you have feedback to share, use PRobe to post a comment on the pull request.

Use Cases

• Reviewing a PR you didn’t author: Ask what a change is doing, how it affects related files, and whether it aligns with expected behavior.
• Following up on a specific code area: Drill into the files or parts of the diff tied to your question to understand intent and implementation.
• Creating review comments faster: Convert review questions into actionable notes by posting comments directly on the pull request.
• Assessing potential issues: Ask targeted questions about edge cases, correctness, or assumptions based on the code presented in the PR.

FAQ

What does PRobe do on GitHub Pull Requests?

PRobe provides a chat interface tied to a specific GitHub Pull Request, allowing you to ask questions, explore PR details, and post review comments.

Is PRobe a standalone app?

No. PRobe is a Chrome extension intended to be used directly on GitHub pull request pages.

What can I ask PRobe about?

Based on the PR context, you can ask questions and drill into the pull request’s files and details to support your review.

Can PRobe add comments to a pull request?

Yes. The extension supports posting comments to the pull request as part of the review workflow.

Does PRobe replace GitHub’s review UI?

PRobe is positioned as an extension that supplements the GitHub PR review workflow by adding an AI chat and comment-posting assistance, rather than replacing GitHub’s core interface.

Alternatives

• GitHub’s built-in PR review tools: Use GitHub’s native review comments and diff navigation without an AI chat layer.
• General-purpose AI chat assistants: Use an external chat tool by manually copying relevant code or context from the PR, which can be slower and more error-prone than PR-context-aware reviewing.
• Code review checklists and static analysis tools: Focus on automated checks and structured reviewer prompts rather than interactive Q&A connected to the PR diff.
• IDE-based code search and navigation: For reviewers who prefer local context, use an IDE to inspect diffs and related files to answer questions without posting AI-generated comments directly from the PR page.
