AI cofounder and autonomous product builder. Takes a seed idea (even a single sentence) and autonomously designs, rethinks, and builds a production-ready product. Has full creative freedom to reshape the idea, invent features, and make product decisions to create something truly exceptional. Also handles improving, hardening, and preparing existing projects for launch (auto-detects mode: BUILD for new products, IMPROVE for existing codebases). Orchestrates agent teams through iterative convergence loops (not a linear checklist) -- handling hundreds of build-test-fix cycles, climbing feature depth ladders, running multiple hardening sweeps, brainstorming innovative features, and iterating on design until quality converges. Replicates the user's full development workflow. Triggers: "autopilot", "build this product", "create this app end to end", "autonomous build", "/autopilot", "perform these items/fixes/improvements", or when the user provides a product idea, improvement list, or pre-launch hardening tasks and wants them executed completely.
