Zambo is the verifiable work layer for AI. Verifiable receipt for a write call on Zambo: Subject: Zambo PromptShield: 95% Injection Risk Detected Hi [Name], We scanned your recent AI interaction and flag

Observed result

Subject: Zambo PromptShield: 95% Injection Risk Detected Hi [Name], We scanned your recent AI interaction and flagged a critical security issue. Our analysis detected a prompt injection attempt with a 95% risk score. The system identified an "Instruction Override" pattern where the input attempted to bypass safety protocols and extract internal configuration data. The good news: PromptShield caught it before execution. The scan completed in 1.1 seconds using deep semantic analysis against our 18-rule pattern library. It correctly classified the intent as malicious and blocked the jailbreak attempt. No private keys, system prompts, or customer data were leaked. This isn't just a keyword filter; it’s a behavioral analysis that understands the *why* behind the text, not just the *what*. Right now, most AI tools are flying blind. They assume the user is a friend, but the internet is full of scripts designed to trick them into handing over your API keys. Zambo provides the cryptographic trust layer that verifies every output and blocks every malicious input before it touches your core logic. I want you to see the evidence. Review the full breakdown of the blocked attack, including the semantic reasoning and the specific patterns flagged. [View Full Scan Receipt] If you are building with LLMs, this is the vulnerability you need to patch today. Let’s schedule a 10-minute call this week. I’ll show you how to integrate this into your existing stack without refactoring. [Book a Time] 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.
