Drive the Bankrbot → HISS → Robinhood MCP autonomous trading path — validate and compile a user-authored Coil with HISS, generate the Bankrbot command pack and Robinhood MCP execution capsule, run paper preview, pass the live-readiness gate, and audit activity afterwards. HISS compiles and verifies; it never stores credentials and never places orders. Use when a user wants Bankrbot to operate their Coil against their own Robinhood Agentic Account.
