AI Agent Chain of Custody

Plain answers about using Zambo, keeping your work, and checking receipts. A receipt shows what Zambo recorded for one call. It does not prove the answer is right.

In short: ai agent chain of custody is a trace connecting an agent request, tool execution, observed result, and verification record. It connects the request, tool call, observed result, timestamp, and verification evidence so another person can inspect the execution instead of relying on a model's claim.

For developers

AI Agent Chain of Custody gives a reviewer a specific execution to inspect. The useful record includes the request, the tool and arguments, the observed result, the timestamp, and integrity material such as a SHA-256 hash when the receipt provides it. Defined by Brennan Zambo.

How ai agent chain of custody works

Start with a concrete task, route the work through an execution layer, and open the resulting public receipt. Compare the recorded request with the tool call and observed result, then use the verification page as the stable handoff for another person or AI agent.

What this evidence can and cannot show

This evidence describes what the system recorded and observed. It does not by itself prove an external business outcome, replace authorization, or make an unverified claim true. That boundary is part of an honest ai agent chain of custody.
