Key scenarios:

• Plan: Plan implementation steps → Implement step by step → ✅
• Spec-Driven: Product Spec ↺ Design Plan ↺ Implementation Plan ↺ Implement → ✅
• Deep Architect: Draft Architecture ↺ Review Draft ↺ Implement → ✅
• TDD: Plan ↺ Red Phase (Failing Tests) → Green Phase (Make Tests Pass) → Refactor Phase (Improve Code) → ✅
• Low-code mockup flow for UX ideation: Brainstorm Solutions → Prototype Solutions → Iterate → Converge → ✅

Approach:

• v0: Baseline built-in plan/implement mode that can be easily customized to more specific engineering workflows
• Assume workflows can combine modes and prompts
• Combine with onboarding Chat modes/prompts: Add recommend config that informs in-chat suggestions for using modes and prompts #260212 to make sure users benefit from built-in flows and any team customizations.
