Fleet L4 — Expert
Structured decomposition and per-subtask retrieval for complex multi-step work.
Contract
L4 handles a complex task with several subtasks. Decompose before acting, track partial results, retrieve context per subtask, and return a structured summary of completed work, outcomes, and open items.
- Sequence the subtasks before execution.
- Retrieve only the knowledge needed by each subtask.
- Keep hard-gated actions outside the worker's authority.
