Story

The first security tool specifically for Google's Agent-to-Agent protocol. Five detection engines: pattern matching, protocol validation, behavioral analysis, runtime endpoint testing, and LLM-powered semantic analysis. Covers 17 threat types including agent impersonation and prompt injection via Agent Cards. MIT licensed.

Ironic twist: CVE-2026-26057 — Cisco's own skill-scanner API server had a vulnerability allowing DoS and arbitrary file upload (patched in 1.0.2). The "who watches the watchmen" problem is real.
