Auto-detect GitHub PR review requests and launch Claude Code review sessions

[dhilgaertner]

Summary

Monitor the authenticated GitHub user for incoming pull request review requests and automatically set up Claude Code sessions to perform code reviews.

Problem

When someone requests your review on a GitHub PR, you have to manually clone/checkout the repo, read through the changes, and write review comments. Crow could automate this workflow.

Proposed Solution

PR Review Monitoring

• Poll or webhook-listen for PRs where the current GitHub user has been requested as a reviewer
• Display pending review requests in the Crow UI (possibly in the tickets/sessions area)

Automatic Review Session Setup

When a review request is detected:

1. Clone the repo into a dedicated review directory: {devRoot}/crow-reviews/{repo-name}/
2. Check out the correct branch for the PR
3. Create a Crow session for the review
4. Launch a Claude Code session with a code review skill

Code Review Skill

Create a new skill (e.g., /review-pr) that:

• Reads the PR diff and description
• Understands the context of the changes
• Provides a thorough code review
• Posts review comments back to the GitHub PR

Implementation Phases

Phase 1: Manual trigger — user clicks a button to review a specific PR
Phase 2: Automatic detection — poll GitHub API for review requests
Phase 3: Full automation — auto-clone, auto-session, auto-review with user approval gate

Notes

• The crow-reviews folder keeps review clones separate from active development worktrees
• Should clean up review clones after the PR is merged/closed
• Consider rate limiting and notification preferences
• Need to handle the case where the user already has the repo cloned elsewhere
