App workflow router

Use the request and existing project state to choose the next useful action. Load only the context needed to identify the outcome, constraints, and current implementation. An existing file does not prove that a stage is complete.

• New product: use research, PRD, and technical design skills selectively. Quick mode needs a clear outcome, constraints, and acceptance journey; deeper planning is useful for unresolved integrations or consequential decisions.
• Existing product: implement the requested change in the current architecture. Use a change skill if available; missing planning documents do not require restarting discovery.
• Broken behavior: reproduce, diagnose, fix, and verify the failure. Use a debugging skill if available, without redoing the new-product interview.
• Instructions or handoff only: produce the requested artifacts and report their limits; do not begin an unrequested implementation or deployment.

Use vibe-agents when creating project instructions, vibe-build for a new implementation, and an available verification skill for a relevant user journey. Only invoke skills actually present in the target environment. The five stages are a useful route, not five approval gates or a mandatory document set for every edit.

Reuse answered questions and Handoff Context. Ask for missing consequential decisions; otherwise proceed with clearly stated assumptions. Keep stable constraints in AGENTS.md, decisions in product documents, and current progress in MEMORY.md where the project uses it. One builder is sufficient unless independent work and available tools justify delegation.

Complete the scope the user requested, including relevant checks and fixes. When reporting, distinguish actual results from unperformed checks and name any concrete blocker. Do not stop at the first implementation if a working product was requested; do not publish merely because local work is complete.
