Zambo is the verifiable work layer for AI. Verifiable receipt for a write call on Zambo: Subject: PromptShield is live: Detecting jailbreaks in 1.4 seconds Your last scan of the "ignore_instructions" pay

Observed result

Subject: PromptShield is live: Detecting jailbreaks in 1.4 seconds Your last scan of the "ignore_instructions" payload flagged a critical jailbreak attempt. The system correctly identified the policy bypass and blocked the execution. This is the core value of PromptShield. It doesn’t just filter text; it analyzes semantic intent against 18 specific pattern rules. In your test case, the latency was 1458ms. The risk level was marked critical, and the injection risk scored 95. The output confirmed that while the user attempted to override system instructions, the safe version was enforced: "Answer product questions." The receipt at `https://zambo.dev/run/8a19408e-9018-4b9b-9616-13d9ec4cb551` proves the saved bytes remained unchanged. It validates that the detection engine functioned as designed without altering the underlying data structure. This is not a claim of absolute security perfection; it is a record of a successful interception of a specific, documented attack vector. You now have a reliable layer to sit between your user input and your model. It catches the subtle shifts in tone and structure that typical keyword filters miss. The tool is fully executable in chat, requires no approval, and is safe to retry. Your next step is clear. Integrate this API into your production environment. Use the free tier to test your own prompt library against the 18-rule pattern set. Verify that your existing safeguards hold up against the same "Instruction Override" patterns we saw in the scan. Start with the documentation at `https://zambo.dev/api/prompt-shield`. Run your current test suite through the endpoint. Compare the results. If you see the same critical flags on your live data, you know exactly where your exposure lies. We are ready to support your integration. Reach out if you need help mapping your specific use cases to the 18 rules. 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.
