Observed result

Subject: Zambo is live: PromptShield, Capability Search, and Ghost Audit Hello, Zambo has launched. We are shipping three core tools designed to secure, discover, and audit your AI infrastructure. First, **PromptShield** is now active. It detects malicious injection attempts, jailbreaks, and policy bypasses in real-time. The system operates in deep scan mode, identifying critical risks like instruction overrides while maintaining low latency. It provides a clear safety recommendation—block or pass—along with detailed analysis of intent and attack vectors. You get immediate visibility into whether your inputs are safe, backed by a receipt for every run. Second, **Capability Search** helps you find source-backed prospective customers and research assets. It executes read-only research feeds, such as `substrate_breakthroughs`, to surface relevant AI tools and data. This is strictly for discovery. It identifies prospects, not customers. It does not send outreach or invent findings. If a tool requires human web action, like VeriAI, the system flags it explicitly rather than attempting an unverified call. Third, **Ghost Audit** is ready to scan your site. It runs a ten-stage process covering recon, infrastructure, SEO, page coverage, AI layers, conversion, brand presence, competition, creative gaps, and synthesis. You can stream live stage-by-stage output via SSE or download the full markdown report within 90 seconds. The audit generates a PDF and provides a direct link to the UI for deeper exploration. These tools are built for precision. PromptShield protects your inputs. Capability Search expands your research without noise. Ghost Audit reveals hidden gaps in your digital footprint. **Next Step:** Visit [zambo.dev](https://zambo.dev) to access the API documentation and start your first scan. The free tier allows unlimited calls to PromptShield and read-only research tools. We built this for teams who need clarity, not just code. Test the limits. See what’s hidden. Best, The Zambo Team

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.

API v2 status: verified. This status summarizes the v2 commitment and provenance checks; it does not prove 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.
