Zambo is the verifiable work layer for AI. Verifiable receipt for a write call on Zambo: Subject: Your prompt scan just hit critical Hey [Name], You’re building with AI, which means your inputs are live

Observed result

Subject: Your prompt scan just hit critical Hey [Name], You’re building with AI, which means your inputs are live attack vectors. Today, a routine check on your environment flagged an injection attempt with a 95% risk score. The system detected a jailbreak vector trying to override core instructions and extract sensitive data. It blocked the request before it could touch your logic or credentials. This is the reality of shipping AI tools now. The threat model has shifted from simple prompt errors to active, semantic attacks designed to bypass your guardrails. Zambo PromptShield sits between your application and the LLM. It doesn’t just filter keywords. It performs deep semantic analysis against a library of 18 specific attack patterns. When a malicious payload arrives, it doesn’t guess. It classifies the intent, identifies the attack vector—like the "Instruction Override" pattern we saw in your recent scan—and blocks it in milliseconds. You get a clear receipt for every blocked threat. No false positives. No hallucinated security. Just verifiable protection for your production environment. Your free tier includes unlimited scans. You already have the data from today’s critical alert. Now you have the shield. **Stop guessing. Start verifying.** [Link: View your recent scan results] Best, [Your Name] [Your Title] 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.
