How Can AI Agent Tools Prove Their Work?

Last updated: 2026-10-03

In short

AI agent tools can provide evidence when the execution system records a call and its observed result. A verifiable receipt lets another person inspect that saved record without treating a status message as proof.

Record the action at its boundary

Keep the tool name, time, request boundary, and observed result with the execution record. A reviewer can then open the receipt and compare the saved data with its integrity information.

What a verifiable receipt does not prove

A receipt supports a claim about recorded work, not every claim an agent makes. It cannot establish answer quality or an outside state change that was never observed.

Next step

Check a saved record with the public receipt verifier.
