Observed result

Subject: Zambo is live: PromptShield, Capability Search, and Ghost Audit You’ve likely seen the noise around prompt injection and AI hallucinations. We built tools to stop it at the source. Zambo is now fully operational. We are not promising perfection, but we are delivering verifiable infrastructure. Here is what is live today: **1. PromptShield** This is your first line of defense. It scans inputs for jailbreaks, policy bypasses, and instruction overrides before they reach your model. The recent scan of a malicious payload was flagged instantly—95% injection risk, critical severity—and blocked. It doesn’t guess. It intercepts. **2. Capability Search** Finding the right tool for an AI task is a bottleneck. This feature maps your query to executable tools or web flows. Whether it’s a read-only research feed or a human-in-the-loop verification step, it tells you exactly what is callable and what requires manual action. No more guessing which APIs work with your stack. **3. Ghost Audit** We audit your site’s AI-readiness in real-time. The current run is processing ten stages, from infrastructure to competitor analysis. You get a live stream of the findings and a full markdown report within 90 seconds. It’s a diagnostic, not a magic fix. It shows you where your AI layer is weak. **The Bottom Line** A receipt proves the bytes were saved. It does not prove the logic is correct. That is on you. These tools give you the data to make that judgment call faster. **Next Step:** Run a free scan on your current input pipeline. [Link: https://zambo.dev/api/prompt-shield] If the risk level stays green, you are safe. If it turns red, you know exactly why. Best, The Zambo Team

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.
