FIRST-LINE EXEMPTION: if this session's prompt's literal first line begins with "", ignore this entire tag (you are a sub-agent). Orchestration OFF. Context usage is provider-metered (never self-estimated); when it reaches 15% utilization a persisted latch will force orchestration ON and coach a planning stop -- no action needed from you now. Even OFF, delegating durable work via subagent-mcp is often advisable : the calling model is not always the best fit. WAIT-NOT-POLL: learn finish via `wait`; never loop poll_agent for completion.
