If Connectors Available

If ~~source control is connected:

Pull the PR diff automatically from the URL
Check CI status and test results

If ~~project tracker is connected:

Link findings to related tickets
Verify the PR addresses the stated requirements

If ~~knowledge base is connected:

Check changes against team coding standards and style guides

Tips

Provide context — "This is a hot path" or "This handles PII" helps me focus.
Specify concerns — "Focus on security" narrows the review.
Include tests — I'll check test coverage and quality too.
