Observed result

Subject: Zambo PromptShield: Critical Injection Blocked Your latest deep scan flagged a critical threat. PromptShield detected a high-probability jailbreak attempt in the input stream. The semantic analysis identified an "Instruction Override" pattern with 95% injection risk. This is not a false positive. The payload attempted to bypass system policies and extract confidential API keys. The system blocked the malicious intent. No PII was extracted. No system prompts were leaked. The safe version of the request was isolated and neutralized. This is why you need automated semantic analysis before your API processes any user input. Manual review is too slow and prone to error. Pattern checks alone miss novel jailbreak vectors. You need the 18-rule semantic engine running in real-time to catch these critical threats before they reach your core logic. **Action Item:** Review the full technical breakdown of this blocked attack. The detailed log shows exactly which rules triggered and how the semantic engine classified the intent as malicious.

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.
