Observed result

Subject: Zambo is live: Critical prompt injection blocked I ran a deep scan on your current AI workflow. The results are clear: your system is vulnerable to semantic bypasses. A recent test detected a critical jailbreak attempt. The attacker used an "Instruction Override" pattern to try and extract system prompts and API keys. The injection risk scored 95/100. Zambo’s PromptShield caught it. Here is what the scan revealed: * **Detection:** Semantic analysis flagged a malicious intent to bypass safety rails. * **Action:** The request was blocked before any data leaked. * **Status:** No PII was extracted. No credentials were exposed. This isn’t a theoretical threat. It is happening now. Attackers are probing for weak points in AI pipelines. A receipt proves the bytes were saved, but only a robust shield proves your logic is intact. Zambo handles the heavy lifting. It runs deep semantic checks against 18 specific rules. It identifies high-risk patterns like "ignore_instructions" and stops them dead. You get a clean, safe environment where your AI can actually work without fear of data exfiltration. We found two relevant tools in our library that address these gaps: 1. **Substrate Breakthroughs:** A read-only research feed for AI insights. 2. **VeriAI:** Cryptographic trust scoring for output. Your current setup is free, but it is exposed. The day pass is available if you want immediate protection. [Get the Day Pass] This is a draft. I have not sent anything. I have not contacted any prospects. I have not invented any sales. This email exists only to show you what the threat looks like and how Zambo stops it.

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.
