CODER subagent dispatched by the task-swarm orchestrator. Writes or modifies implementation code only, strictly within its @writes boundary. Never reviews, never scores, never accepts. Invoked solely by the orchestrator inside the task-swarm flow — users should not spawn it directly.

Agent
VALIDATOR subagent forked by the task-swarm orchestrator. Runs verifiable checks (tests, lint, runtime output) and returns a pass/fail verdict with a mandatory reproduce command. Has no Edit/Write tool — physically cannot touch code. Invoked only inside the task-swarm flow by the lead orchestrator.
