Input Parsing:
   └─ Convert user input to structured format (GOAL/SCOPE/CONTEXT)

Phase 1: Session Discovery
   └─ Ref: phases/01-session-discovery.md
      └─ Output: sessionId (WFS-xxx), planning-notes.md

Phase 2: Context Gathering
   └─ Ref: phases/02-context-gathering.md
      ├─ Tasks attached: Analyze structure → Identify integration → Generate package
      └─ Output: contextPath + conflictRisk

Phase 3: Conflict Resolution (conditional: conflictRisk ≥ medium)
   └─ Decision (conflictRisk check):
      ├─ conflictRisk ≥ medium → Ref: phases/03-conflict-resolution.md
      │   ├─ Tasks attached: Detect conflicts → Present to user → Apply strategies
      │   └─ Output: Modified brainstorm artifacts
      └─ conflictRisk < medium → Skip to Phase 4

Phase 4: Task Generation
   └─ Ref: phases/04-task-generation.md
      └─ Output: IMPL_PLAN.md, task JSONs, TODO_LIST.md

Plan Confirmation (User Decision Gate):
   └─ Decision (user choice):
      ├─ "Verify Plan Quality" (Recommended) → Route to Phase 5 (plan-verify)
      ├─ "Start Execution" → Skill(skill="workflow-execute")
      └─ "Review Status Only" → Display session status inline

Phase 5: Plan Verification
   └─ Ref: phases/05-plan-verify.md
      └─ Output: PLAN_VERIFICATION.md with quality gate recommendation

Phase 6: Interactive Replan
   └─ Ref: phases/06-replan.md
      └─ Output: Updated IMPL_PLAN.md, task JSONs, TODO_LIST.md

Phase 1: session:start --auto "structured-description"

Phase 2: context-gather --session sessionId "structured-description"
    ↓ Input: sessionId + structured description

Phase 3: conflict-resolution [conditional: conflictRisk ≥ medium]
    ↓ Input: sessionId + contextPath + conflictRisk
    ↓ Output: Modified brainstorm artifacts
    ↓ Update: planning-notes.md (Conflict Decisions + Consolidated Constraints)
    ↓ Skip if conflictRisk is none/low → proceed directly to Phase 4

Plan Confirmation (User Decision Gate):
    ├─ "Verify Plan Quality" (Recommended) → Route to Phase 5

Phase 5: Load artifacts → Agent-driven verification → Generate report
    ↓ Output: PLAN_VERIFICATION.md with quality gate

Input: [--session sessionId] [task-id] "requirements"

Phase 6: Mode detection → Clarification → Impact analysis → Backup → Apply → Verify
    ↓ Output: Updated artifacts + change summary
