  "description": "Real-time guard on five Claude Code pre-execution hook events (tool calls, permission decisions, submitted and expanded prompts, and subagent creation) plus a response-end advisory that flags an action leaking a secret, installing a malicious package, or exfiltrating data, plus the skarn-audit skill (scan sessions and vet configs, redacted). Ships in audit mode, which reports the verdict and never changes what the agent does; blocking needs enforce mode, which registering alone does not unlock. Backed by the Skarn detection engine. It also declares one local MCP server, named skarn, with four tools (scan_sessions, vet_configs, list_sessions, session_stats): every tool is read-only, none of them writes or changes a file, none of them makes a network call, and every matched value comes back masked.",
