Project Builder
Install Project Builder from the Pick Experts step at onboarding. It’s an interactive Expert that takes a large feature from idea to shipped code in five optional steps: product design, architecture (with Mermaid diagrams), ticket breakdown, orchestration — launching a PR Author worker per unit of work in synchronous dependency waves — and comms, reporting when PRs are ready for review and when the feature is complete. You can start from scratch or drop in an existing starting point — a Figma mockup, a Notion or Google doc, an existing PR, a ticket, or a rough spec — and enter at any step. The Expert researches the repo, drafts a design doc, iterates with you, breaks the work into tickets, and dispatches implementation to PR Author workers. It never merges implementation PRs and never writes feature code itself; the PR Author workers and human reviewers own those.- Best for: Features too large for a single PR — anything that needs a reviewed design and several coordinated implementation PRs.
- How to use: Start a session with the Project Builder Expert and describe the feature, or paste a link to the doc, mockup, PR, or ticket you want to start from. Review and iterate on the design doc it produces, then let it break the work down and orchestrate the implementation.
