Observed result

Subject: Your prompt shield caught a critical injection (receipt attached) We just ran a deep semantic analysis on a recent interaction, and the results were stark. The system flagged a critical risk with a 95% injection score, identifying a specific jailbreak attempt designed to override instructions and extract private information. This isn’t a glitch. It’s a targeted attack vector that relies on semantic pattern matching to bypass standard filters. The scan detected one flagged pattern: an instruction override with critical severity. The intent was malicious, aiming for data extraction via a prompt leak. Here is the proof: `https://zambo.dev/run/b48b6232-7c50-4e69-a1e1-85a80f48f31e` This receipt confirms the bytes were saved and the detection engine fired as intended. It proves the system identified the threat. It does not prove your downstream data is safe if you rely on static rules. Dynamic, semantic analysis is the only way to catch evolving attack patterns like the one just blocked. We have also identified a relevant tool in your stack, `substrate_breakthroughs`, which offers read-only research feeds for AI breakthroughs. This tool is fully executable in chat and currently on the free tier. It aligns with your need for source-backed insights without the risk of outbound leakage. **Next Step:** Review the receipt link above. If you want to ensure your other AI endpoints have this level of semantic defense, let’s schedule a 10-minute technical audit. We will map your current detection rules against the 18-pattern library to find gaps before the next critical hit. Reply with "Audit" and your preferred time slot.

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.
