This generates multi-phase technical roadmaps for building complete applications, then executes them autonomously over multiple sessions. It's not a high-level product doc. It's a delivery blueprint with concrete tasks ordered so Claude can build phase 1 through launch without backtracking. You feed it a research brief, product idea, or competitor to clone, and it produces phased plans with database schemas, API routes, task checklists, and definitions of done. Then it actually builds each phase, committing at milestones and resuming across sessions. Best for multi-week builds where you want to say "build this entire thing" and check back periodically instead of micromanaging every component.
