Add Zambo to your AI

A handover brings the recorded AI work and its verifiable receipts into one proof link. Review the evidence behind each claim, check what was and was not observed, then Accept or Flag.

In short: append-only ai agent log is a log that records new agent events without rewriting earlier execution history. 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

Append-only AI Agent Log 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 append-only ai agent log 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 append-only ai agent log.

How do I use free append-only ai agent log?

Use a concrete task and inspect the public receipt for the request, tool call, observed result, timestamp, and verification evidence.

Can append-only ai agent log for compliance prove an external outcome?

No. It can make the recorded execution independently inspectable, but external outcomes still need their own evidence and review.

LIVE WORKED EXAMPLE
Open a live AI agent receipt and check its verifier. Inspect the tool call, timestamp, and observed result. A verified record does not prove an unobserved outside outcome.
