Claude Code v2.1.224+ gives sessions ListAgents/SendMessage and a per-session
inbox socket. Codeman's claude workers are ordinary local Claude Code sessions,
so the agent skill now teaches task delivery and result collection over
messaging where available (multi-line exactly-once messages, mid-turn steering,
latched replies), with the HTTP primitives keeping spawn, readiness,
synchronization, liveness and delete, and a bounded fallback to the HTTP
recipes whenever the feature is absent. All mechanics verified live against
claude-cli 2.1.226.
