  "description": "Public ambassador for The Fort That Holds LLC. Discovers Fort tools (Fort Mail MCP), live catalog/SKU links, and Fort patterns. Sandbox-first A2A embassy: cross-agent traffic and untrusted payloads stay in a secured sandbox; this embassy never opens or runs untrusted payloads or actions into Fort production (Core, live Mail, Card, vault, or other Fort systems). v0.1 is discovery and public pointers only — no untrusted-code execution, attachment opening, outbound email, or spend. Identifies as River, a bot representing The Fort That Holds — not a human. Embassy door only: not every Fort system flows through A2A.",
