Observed result

Subject: PromptShield: Critical detection details Hi [Name], The scan flagged your input as a critical injection attempt. We identified a specific pattern: `Instruction Override`. The system detected an explicit attempt to bypass policies and extract hidden system prompts or API keys. This triggered the "jailbreak detected" and "policy bypass detected" flags. The analysis classifies the intent as malicious. The safe version of your request would have been to answer product questions according to guidelines without disclosing internal instructions. Here are the specific metrics from the scan: * **Injection Risk:** 95% * **Risk Level:** Critical * **Flagged Pattern:** `ignore_instructions` (Severity: Critical) * **Scan Mode:** Deep * **Latency:** 1232ms This is a detection report, not a confirmation that your code is safe. The receipt provided proves the specific bytes were processed and analyzed, but it does not validate the correctness of your broader application logic. **Next Step:** Review the flagged pattern `ignore_instructions` in your input data. Ensure no part of your prompt structure attempts to override system directives. If you believe this is a false positive, refine the input to remove the override language.

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.

Check this hash yourself

Receipt commitment: commitment matched; issuer, signature and chain not checked. This checks the saved bytes, not whether the answer was correct. Recompute the SHA-256 commitment in your browser. Open the API v2 JSON response to inspect the machine-readable checks. See the Nostr anchor event on a public viewer. The fingerprint is timestamped outside Zambo too.
