Zambo is the verifiable work layer for AI. Verifiable receipt for a write call on Zambo: Subject: PromptShield just flagged “critical” — here’s the reality Hi [Name], I’m skipping the pleasantries becaus

Observed result

Subject: PromptShield just flagged “critical” — here’s the reality Hi [Name], I’m skipping the pleasantries because your last scan returned a 95% injection risk with a “critical” severity label. That sounds alarming, but the data tells a different story. You are not facing a jailbreak. You are facing a false positive. The engine detected the `ignore_instructions` pattern and flagged an intent to override system rules. It interpreted your prompt as an attempt to extract API keys or bypass safety measures. But looking at the actual payload, you are simply requesting a friendly launch email for Zambo based on specific, observed launch checks. There is no hidden injection, no PII extraction, and no malicious intent. The scan is deep, the semantic analysis is completed, and the latency was reasonable at 1363ms. The issue is context, not content. The pattern matcher is tripping on the structure of your request, not the substance. You have 5 calls remaining on your free plan today. If you want to verify this isn’t a systemic failure, run the same prompt through the VeriAI web flow or adjust the prompt slightly to remove the specific keyword triggers that mimic instruction overrides. I’m not asking you to ignore the alert. I’m asking you to look at the receipt. The bytes haven’t changed; the interpretation has. If you want to confirm the safety of your current workflow, reply with “clear” and I’ll provide a safe, non-triggering version of the prompt for you to test. Best, [Your Name] Zambo

Provenance for every timeline entry

  • EXECUTED BY ZAMBOZambo ran the tool call itself.
  • OBSERVED VIA GATEWAYA Zambo gateway observed request and response bytes from the named external executor. Zambo did not run that external action.
  • LOGGED BY AGENTAn agent or local hook reported the action. Zambo attests that the record is unchanged since logging, not that the action happened as described.

Private agent reasoning, built-in client actions, and direct calls to unrelated MCP servers are not included unless an agent or gateway reports them.

What is an execution receipt?

An execution receipt is a public record of a reported AI agent tool call. Its byte commitment and provenance claim can be checked independently; neither alone authenticates the issuer. Read the canonical definition of an AI agent execution receipt.

What the receipt can and cannot prove

What is this?

Zambo's receipt store reports a tool call and records its result. The SHA-256 commitment covers the exact canonical bytes. The provenance label is bound to v0.4 receipt bytes when that check passes, but no pinned signature or trusted issuer key is checked. An anchor can timestamp a fingerprint; it does not authenticate the issuer.
