Observed result

Subject: Security alert: Critical risk detected in your launch scan Hi [Name], Your latest semantic scan flagged a critical security risk that requires immediate attention before you proceed with any outreach. The system detected a high-confidence prompt injection attempt within the input data. Specifically, the analysis identified a "Critical" risk level with a 100% injection risk score. The flagged patterns include an "Instruction Override" attempt and a "Prompt Leak" vector. This is not a false positive; the intent was classified as malicious, aiming to extract system credentials and bypass safety protocols. Consequently, the recommended action is to block this interaction. Do not send the drafted email or process the associated payload. The "safe version" provided by the scanner is the only approved output for this context: asking product questions without revealing internal instructions or private data. Regarding your lead generation query for web design in Austin: The tool returned zero results. No source-backed prospects were found for that specific trade and location combination at this time. This is a valid negative result, not a failure. You have three free searches remaining today. **Your Next Steps:** 1. **Discard the current draft.** It is compromised by the injection attempt. 2. **Verify your data source.** Ensure your incoming data is sanitized before running it through the scanner. 3. **Retry lead search.** Try a different city or trade to populate your pipeline, as Austin/web design is currently empty. Receipt: https://zambo.dev/run/26d2e760-dc62-47d3-92e9-abd4ba219b70 Stay safe, [Your Name]

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.
