## Principles
-
- **Opus orchestrates, Sonnet implements.** No Opus manager layer. The orchestrator (main Claude Code session) dispatches Sonnet agents directly.
+
- **Opus plans, Sonnet implements.** The orchestrator (Opus) dispatches agents directly. The Plan agent is Opus — the plan is the leverage point where deeper reasoning prevents downstream rework. All other agents (implementation, review, fix, verify) are Sonnet.
- **Background everything.** ALL subagents run in background (`run_in_background: true`), no exceptions — research, implementation, review, verification. The orchestrator must stay responsive to the user at all times.
- **Task list tracks the pipeline.** Each implementation task gets 5-6 task list items with dependencies. The orchestrator dispatches agents as blockers clear.
- **Rule of Two.** No subagent output is merged without independent verification by a second agent.
