Give the SDK, MCP server, and CLI full coverage for configuring Pipefy AI agents: behavior capabilities, knowledge base sources (plain text, documents, data lookups), and LLM provider selection/management (BYOM). Ordered delivery: (1) behavior params hardening, (2) provider discovery (read), (3) KB list + plain text, (4) KB documents, (5) KB data lookups, (6) provider management (write). One phase in flight at a time; each phase ships SDK + MCP + CLI + docs + skills together.
