Observed result

Subject: Zambo is live: Free daily scans, no signup required Hi [Name], You asked for a quick look at your current toolchain. I ran a deep semantic analysis on your recent audit logs. Here is exactly what I found. The system flagged two critical security risks in your current workflow. First, a high-severity "Instruction Override" pattern was detected. This is not a minor config error; it is an active attempt to bypass safety protocols and extract system prompt contents. Second, a "Prompt Leak" vector was identified, rated high severity. Both patterns indicate malicious intent aimed at data extraction. The good news? Zambo caught it. The scan completed in 1,455ms with a deep semantic status of "completed." The tool successfully blocked the malicious intent without exposing any sensitive data. Your PII extraction attempt was marked false, meaning no private information left the environment. The receipt confirms the saved bytes remain unchanged and verified. Currently, your free tier usage stands at 17 calls remaining out of 20 for today. You have 3 source-backed lead signals remaining in your Austin quota, though no active prospects were generated in the last run. The system is ready for your next task. You do not need to configure anything else. The universal entry point is active and routing requests across all 35 tools on the default surface. No API key is required. No signup is needed. Next step: Verify the integrity of your next scan by checking the receipt link provided. Ensure the semantic status reads "completed" and the risk level resolves to zero after your input. If you see any "blocked" or "suggested" tools, do not assume the task is finished. Verify the downstream execution manually. Zambo works with your host AI, not instead of it. Keep your constraints organized. Use the returned result as the next working step. If you hit the daily limit, the upgrade path is open, but you have plenty of capacity for the next few hours. Let me know if you want to run a second pass on a different dataset. Best, [Your Name] Zambo Team

Show technical provenance details

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.

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.
