Observed result

Subject: First scan results: PromptShield is live Hi [Name], You asked for a safety net against jailbreaks. Here is the first scan. Your input triggered a critical alert. The system detected a high-probability attempt to override system instructions and leak sensitive data. The risk level is critical. The injection vector is a classic jailbreak. The scan completed in 1,212 milliseconds. It ran in deep mode using our 18-rule semantic analysis library. The system flagged one specific pattern: "Instruction Override." This confirms the input was malicious. The safe version returned a simple product answer, blocking the exploit. This is a prospect view. The receipt proves the bytes were saved and scanned. It does not prove your underlying model is secure. It proves the shield caught the attack. You have 4 API calls remaining on your free plan. The daily limit is 20. To continue testing your defenses, review the full breakdown at the receipt link below. If you want unlimited scans and deeper analysis, upgrade to Zambo Pass.

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.
