+**Core Philosophy**: Minimal friction, maximum velocity. Simple tasks = no artifacts. Complex tasks = lightweight planning doc in `.workflow/.scratchpad/`.
 
 ## Overview
 
-**Zero-artifact workflow**: Clarify → Select Tools → Multi-Mode Analysis → Decision → Direct Execution
+**Complexity-aware workflow**: Clarify → Assess Complexity → Select Tools → Multi-Mode Analysis → Decision → Direct Execution
 
-**vs multi-cli-plan**: No IMPL_PLAN.md, plan.json, synthesis.json - all state in memory.

 ## Execution Flow

 Phase 1: Clarify Requirements → AskUser for missing details
+Phase 1.5: Assess Complexity → Determine if planning doc needed
 Phase 2: Select Tools (CLI → Mode → Agent) → 3-step selection
 Phase 3: Multi-Mode Analysis → Execute with --resume chaining
 Phase 4: User Decision → Execute / Refine / Change / Cancel
-Phase 5: Direct Execution → No plan files, immediate implementation
