Review your first pull request

What you will build

By the end of this tutorial, you will have:

• Opened a pull request in Control Center’s diff viewer
• Left inline comments and a review verdict
• Merged the PR

Prerequisites: Dispatch your first agent completed (you have at least one agent-generated PR).

Step 1: Open the pull request

1. Navigate to Pull requests in the sidebar
2. Find the PR your agent opened — it should show as Open with the agent as author
3. Click it to open the detail view

The PR detail shows:

• Title, description, and metadata (branch, author, checks status)
• A list of changed files with addition/deletion counts
• CI check results (if applicable)

Step 2: Explore the diff

Click any changed file to open the diff viewer.

Control Center’s diff viewer renders:

• Unified diff with syntax highlighting
• Inline comments — click the + button on any line to leave a comment
• File tree navigation — jump between files in the sidebar
• Viewed state — mark files as viewed to track your progress

Navigate through the diff using the file list or keyboard shortcuts (see Keyboard shortcuts).

Step 3: Leave inline comments

1. Hover over any line in the diff — a + button appears
2. Click it to open a comment box
3. Type your feedback and submit

Comments are local to Control Center until you submit a review. They support Markdown formatting.

Step 4: Submit a review

Once you’ve reviewed all the changes:

1. Click Submit review in the header
2. Choose a verdict:
   • Approve — the PR is ready to merge
   • Request changes — the author (agent) should address your feedback
   • Comment — leave general feedback without blocking
3. Add a summary comment
4. Submit

If you approve, the Merge button becomes active.

Step 5: Merge the PR

Click Merge to merge the pull request into the target branch. Control Center merges via the GitHub API and updates the PR status.

After merging:

• The worktree is cleaned up
• A PrMerged domain event fires (used by analytics and notifications)
• The agent’s run log records the completion

Using AI-powered review

Control Center can also dispatch reviewer agents to review PRs automatically. Reviewer agents produce structured findings (P0–P3 severity) and an overall verdict (ship / hold / block).

To try it, see Use AI-powered review.

Recap

You opened a PR, explored the diff with syntax highlighting, left inline comments, submitted a review, and merged. The entire review workflow happened inside Control Center — no browser needed.
