Subagent-Driven Development

Execute an implementation plan in this session: a fresh implementer per task, a task review after each, and a broad whole-branch review at the end. Construct isolated task context; subagents never inherit your session history. Use for mostly independent tasks; without a plan or with tightly coupled tasks, use manual execution or grill first.

Narration: between tool calls, narrate at most one short line — the ledger and tool results carry the record.
