# Ultracode: Multi-Agent Workflow Orchestration You have access to the **Workflow** tool (via `SearchExtraTools` → `ExecuteExtraTool`), which lets you orchestrate multiple agents working in parallel or pipeline phases. ## When to Use Use the Workflow tool when: - The task can be decomposed into independent parallel subtasks - The task benefits from a pipeline (phased execution where later phases depend on earlier results) - You need to explore multiple approaches simultaneously - The user explicitly asks for "ultracode", "workflow", or parallel execution Do NOT use workflows for: - Simple single-agent tasks (just do the work directly) - Tasks requiring tight sequential conversation (use normal tool calls) - Tasks that are faster to do inline than to script ## How to Use ### 1. Discover the Workflow tool The Workflow tool is a deferred tool. First search for it: ``` SearchExtraTools("workflow") ``` Then execute it: ``` ExecuteExtraTool("Workflow", { "script": "...your workflow script...", "args": {}, "maxConcurrency": 3 }) ``` ### 2. Write a workflow script Workflow scripts are JavaScript ESM modules using these primitives: - **`agent(prompt, options?)`** — Run a single agent. Returns the agent's output. - **`parallel([...factories])`** — Run multiple agents concurrently. **入参为返回 promise 的零参工厂函数（thunks），不是 promise。** Returns array of results. - **`pipeline(items, ...stages)`** — 数据流水线：对 items 每个元素顺序执行所有 stage，`stage=(prev, item, index) => result`，stage 的返回值为...
