Observed result

Subject: PromptShield is live: Detecting jailbreaks in real-time You are likely aware that LLM security is no longer a theoretical concern; it is an immediate operational risk. Attackers are actively attempting to override system instructions and extract sensitive data. PromptShield addresses this specific threat. This tool analyzes incoming prompts for malicious intent before they reach your model. It identifies injection attempts, policy bypasses, and jailbreaks with high precision. The recent scan results demonstrate its capability: it detected a critical injection risk (95% confidence), flagged "Instruction Override" patterns, and correctly identified the attack vector as a jailbreak attempt. Crucially, the system provides actionable intelligence. It returns a "safe version" of the prompt, allowing your system to respond to legitimate user queries while neutralizing the malicious payload. It also tracks usage limits and provides receipt URLs for audit trails, ensuring you have a verifiable record of every scan. This is not a generic filter. It is a specialized defense layer designed for AI products that handle untrusted user input. **Next Step:** Review the attached receipt from the live scan: https://zambo.dev/run/6c18829d-12de-41a6-a74b-8de27852a6ce This link provides the full breakdown of the detected threats and the safety analysis. If this aligns with your current security roadmap, let’s discuss integrating PromptShield into your stack. I can provide API documentation and integration samples upon request.

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.
