Deferred MCP tools: in Claude Code the engine's MCP tools are often deferred — not callable until loaded. If a tool below is not directly callable, first run ToolSearch(query="select:mcp__plugin_prd_go__preflight") (keyword fallback ToolSearch(query="+atlas engine preflight", max_results=10)) and use whichever prefix matches (mcp__plugin_prd_go__ or mcp__atlas-engine__).
