Observed result

Subject: Zambo launch: Honest limits, real receipts Hi [Name], I’m skipping the fluff. I ran a diagnostic on Zambo’s current launch capabilities to see what actually works versus what’s just marketing copy. The results are mixed, and I want to be transparent about them. First, the security layer. A deep semantic scan flagged the current prompt structure as a critical risk. It detected instruction override and jailbreak patterns. This isn’t a theoretical possibility; the system marked the injection risk at 100%. Until this is patched, the platform is vulnerable to malicious input. I’m not shipping with that kind of exposure. Second, the lead generation engine. I tested the LeadSignal tool for web design prospects in Austin. The execution completed, but the result was zero leads. The system explicitly stated it found no source-backed prospects and refused to invent contacts. That’s a good sign for data integrity. It means the tool won’t hallucinate fake customers to make me look busy. However, it also means the current database or search parameters are too narrow to yield immediate results for this specific trade and location. Third, the research tool. The `substrate_breakthroughs` function is operational. It provides a read-only feed of AI research breakthroughs. It’s free to access and works as intended. This is a solid feature for early adopters who want real-time insights without paying for a pass. The bottom line: Zambo is not ready for a broad public launch. The security vulnerabilities are critical, and the lead data is currently empty. I am holding off on outreach to potential customers. I will not send automated emails until the risk level drops below critical and we have verified, source-backed leads to show for our work. I need a fix for the prompt injection issue before we proceed. I also need to adjust the LeadSignal parameters or wait for the quota reset to see if broader searches yield better results. Please review the attached receipts for the failed lead scan and the security flags. Once those are addressed, we can talk about next steps. Best, [Your Name] [Your Title]

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.
