How to use

Install:

gem install prreview

Run this command with a PR URL:

prreview https://github.com/owner/repo/pull/123

Or use more options:

prreview --help
prreview https://github.com/owner/repo/pull/123 --all-content --prompt "Are there any security issues?"

Now, just paste the PR details into ChatGPT, Claude, or any LLM for review.

What it does

PrReview collects key details about a PR, including:

• PR description, commits, and comments
• Linked issues
• Changed files and their content
• The full PR diff

It then copies everything to your clipboard.

Why prompt

Advantages over LLM integrations:

• You're free to use the LLM of your choice
• You can continue the conversation with the LLM right in the chat, asking to pay attention to a specific part of the PR
• The gem is simpler

However, in the future we might add some optional integrations.

Tips

• A well-written PR and linked issue description make a big difference — and are good practice anyway.
• Run prreview after you've thoroughly reviewed the PR. It works best when you understand the changes well.
• Don't hesitate to try different LLMs or refresh the response to see if something new comes up.
• Use --all-content and other extra options — they can significantly improve results for some PRs.
• After the LLM responds, to potentially uncover more issues:
  • Ask "Anything else?".
  • If the response has a list of problems, try responding to each of them, giving the LLM more context.

Requirements

• Ruby
• GITHUB_TOKEN environment variable. GitHub Docs
