Use during Trellis planning when creating or refining a PRD. Applies grill-me style clarification: ask one question at a time, inspect code before asking, provide options and a recommended answer, update prd.md after each decision, verify technical facts against latest knowledge with grok-search-mcp before confirmation, and require PRD confirmation before implementation.
Use before codebase exploration, external documentation lookup, live web research, or webpage fetching. Enforces Dream WF MCP priority: fast-context-mcp for semantic code context and grok-search-mcp for external web/docs/fetch tasks.
