Tools (4)

`ground_truth_info`	Get info about the GroundTruth ASP — what it does, pricing, and how to call it
`human_do`	Create a task for a human oracle to complete in the real world. Requires x402 payment. Returns a task_id to poll with task_status.
`review_task`	Review a submitted proof and accept or reject it. Accept releases the on-chain payout to the human oracle; reject fails the task with no payout. Call this after task_status shows the proof.
`task_status`	Check the status and result of a GroundTruth task by its task_id

Schemas: list_tools.
