# go (orchestrator) Pure routing. Reads pipeline state, dispatches to the correct phase skill. **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__`). ## Flow 1. Call `mcp__plugin_prd_go__preflight()` — get environment state 2. Call `mcp__plugin_prd_go__current_phase()` — get pipeline state 3. Route via Skill tool: - current_phase is null or SETUP → invoke `/prd:setup` - current_phase is DISCOVER → invoke `/prd:discover` - current_phase is GENERATE → invoke `/prd:generate` - current_phase is HANDOFF → invoke `/prd:handoff` - current_phase is EXECUTE → invoke `/prd:execute-task` 4. After phase skill returns, re-check current_phase. If it advanced, route to the next phase. If not, report the blocker. ## Stateless routing This skill does NOT hold procedure. Each phase skill owns its own logic. The orchestrator survives context loss because every phase skill reads `current_phase()` on entry. ## Red flags These thoughts mean STOP, you're rationalising: - "I know which phase we're in, skip preflight" → NO. Preflight is cheap. - "The phase skill already ran, I don't need to re-check" → NO. Context might have died. - "I can just do th...
