Orchestrate multi-agent work delegation

Enforce delegation to subagents; coordinator never implements directly

Multi-agent orchestration where a coordinator routes work to specialized agents and each phase has explicit approval checkpoints.

• · User command with intent and context

• · Task delegated to appropriate subagent_type
• · Status report after subagent completion
• · Transition signal if awaiting approval

• · Task tool for subagent creation
• · State files for context (state.json, tasks.md)

• · Coordinator agent architecture (main agent + specialized subagents)
• · SpecKit subagent types defined: constitution-architect, spec-analyst, plan-architect, task-planner, spec-executor, qa-engineer
• · Task tool available in harness

• · Coordinator violates rule and implements directly → loses context separation and auditability
• · Quick mode invoked → coordinator skips delegation and hand-codes artifact (violates principle)
• · Subagent returns incomplete result → coordinator must re-delegate, not finish the work

• · Explicit rule statement: 'YOU MUST NEVER IMPLEMENT ANYTHING YOURSELF'
• · Coordinator pattern diagram showing 7-step flow with explicit Task tool call
• · Subagent type lookup table (6 types with examples)
• · Phase transition rules: awaitingApproval flag, coordinator stops, user runs next command
