Observed result

Subject: Zambo is live: Stop guessing, start verifying You’re likely tired of AI outputs that look plausible but fail under scrutiny. You need proof, not promises. Zambo is now available. It’s not a magic box; it’s a verification layer. We built this because "it works on my machine" isn’t a security posture. Here’s exactly what Zambo does: 1. **Detects Injection Attacks:** It scans prompts for jailbreaks, policy bypasses, and system prompt leaks before they reach your model. 2. **Flags Critical Risks:** It identifies high-severity patterns like instruction overrides and malicious intent. 3. **Provides Audit Trails:** Every scan generates a receipt. This proves the bytes analyzed. It documents the risk assessment. It does not prove your AI is perfect. It proves you checked. We are not selling "trust." We are selling visibility. **The Reality Check** Your competitors are deploying AI agents without guardrails. One successful jailbreak exposes your system prompts, your keys, and your user data. Zambo intercepts this. It’s a deep-scan API that runs in milliseconds. **What’s Included** * **PromptShield API:** Real-time detection of 18 known attack patterns. * **Risk Scoring:** Critical, High, Medium, Low classifications. * **Receipt Generation:** Immutable logs for compliance and debugging. **The CTA** We don’t want your credit card yet. We want your worst-case scenario. Send us one prompt you suspect is vulnerable. We’ll run it through the deep-scan mode. You get the full risk breakdown, the flagged patterns, and the receipt. No account required. No sales call. Just data. Reply to this email with your test prompt. We’ll respond within the hour with the scan results. This is how you build safe AI. Not by hoping for the best, but by checking the worst. Best, [Your Name] Zambo Team [Link to Zambo Documentation] *Note: This email contains no personal data. The receipt link in our internal testing is for demonstration of the log format only.*

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.
