After the AI finishes implementing your spec, review the changes and complete any manual setup steps before creating pull requests.

Phase 4 review with implementation stream and manual setup
The review phase shows:
  • Left panel (50%) — the implementation stream (preserved from Phase 3) so you can review what was done
  • Right panel (50%) — manual setup panel showing any steps you need to complete before creating the PR

​
Manual setup steps

If the implementation requires manual configuration (e.g., environment variables, service credentials, or database migrations), the AI generates a manual-setup.md file with instructions. This appears in the right panel as a checklist you can follow. Common manual setup steps include:
  • Setting environment variables
  • Configuring third-party services
  • Running database migrations
  • Updating deployment configurations
  • Generating API keys

​
PR description generation

When you click Create PR/s, p0 generates a comprehensive PR description based on:
  • Your product spec
  • Completed ticket documentation from completed-tickets-documentation/
  • AI-generated specifications from agent-written-specifications/
The description is generated by Claude and formatted as Markdown. If generation takes too long (over 15 seconds), a fallback description is used instead.

​
Multi-repo PRs

For workspaces with multiple repositories, p0 creates one PR per repository that has changes:
  • Each repo gets its own PR with the same description
  • PRs are tracked independently (separate URLs and statuses)
  • Failed repos can be retried individually in Phase 5

​
Creating the PR

Click Create PR/s at the bottom of the screen. p0 will:
  1. Collect all feature folder documentation
  2. Generate the PR description
  3. Create a PR in each repository with changes
  4. Store PR metadata for tracking
  5. Transition to Phase 5
Make sure you’ve completed any manual setup steps before creating the PR. The manual setup panel is your checklist for pre-PR tasks.
