+  A free, offline static security scanner for AI components
+  (agent skills/plugins, MCP servers, npm & PyPI packages, git repos).
+  Deterministic regex + AST detection (no LLM, no account) with
+  evidence-anchored findings for supply-chain risk, dangerous
+  capabilities, prompt-injection surfaces, MCP tool poisoning and
+  exfiltration paths; maps to the OWASP Agentic Skills Top 10.
+  JSON and SARIF 2.1.0 output, with a GitHub Action and pre-commit hook.
