What tool interfaces could a simulated routing environment expose?

A simulated environment could expose tools such as `search_requests`, `get_queue`, `check_eligibility`, `submit_assignment` and `get_assignment_status`. Each tool should have typed inputs, documented outputs and defined effects on generated state.

An assignment call might require `request_id`, `destination_id`, `reason_code` and `idempotency_key`. The response could return `assignment_id`, `status` and `rejection_reason`. A submitted assignment should remain distinguishable from an accepted assignment, with acceptance represented as a separate transition when the process requires it.

Queue records can expose supported request categories, required referral fields and whether the queue accepts direct assignments. Validation errors can identify missing evidence without silently filling it in. Repeating a call with the same idempotency key should follow the declared contract so retries do not create duplicate work.

A release can include JSON schemas, action examples and generated state fixtures. Developers can bind their agent's tool layer to these contracts and inspect whether it responds appropriately to rejected or incomplete calls.

This gives the environment observable mechanics: the agent's explanation does not change the queue unless an allowed tool action actually changes it.
