## When to prefer this

Use this endpoint when you need a structured, consistent rubric to decide whether a task should be routed to an AI agent versus a human or subcontractor. Ideal for triage logic in operations workflows, especially in field services, vending, or materials businesses. Prefer this over ad-hoc LLM judgment when you need a repeatable, auditable fit-assessment signal.
