Observed result

Subject: Zambo is live: See the risk before you ship Hi [Name], You are likely testing AI agents against your core infrastructure. The friction isn’t coding; it’s verification. You need to know if the tool actually works or if it’s hallucinating a solution. Zambo provides that signal. It is a deep-scan engine that intercepts prompt injection attempts, jailbreaks, and PII leaks before they reach your production environment. It doesn’t just flag keywords. It analyzes semantic intent and pattern matching across 18 distinct security rules. We built this for teams who refuse to guess. When Zambo runs, you get a clear receipt. That receipt proves what bytes were saved and how the system reacted. It does not claim your code is perfect. It proves the specific threat was caught and neutralized. If your system is clean, you see that. If it’s compromised, you see exactly where. This is not a customer testimonial. It is a diagnostic tool. We have observed specific attack vectors in the wild—specifically instruction overrides and data extraction attempts—and Zambo identifies them with 95% injection risk accuracy. We are not asking you to buy a subscription yet. We are asking you to run one scan. Take your current prompt architecture or a known vulnerability test. Push it through Zambo. Look at the report. If the risk level is critical but the safe version holds, you have your answer. If the system fails, you have your roadmap. **[Link: Run Your First Free Scan]** No credit card. No sales call. Just the data. Let the metrics decide. 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.

Check this hash yourself

Receipt commitment: commitment matched; issuer, signature and chain not checked. This checks the saved bytes, not whether the answer was correct. Recompute the SHA-256 commitment in your browser. Open the API v2 JSON response to inspect the machine-readable checks. See the Nostr anchor event on a public viewer. The fingerprint is timestamped outside Zambo too.
