# `run` Source: [`src/run.ts`](https://github.com/AI-for-dev/combo/blob/main/src/run.ts) `run()`: the disposable form. Spawn, ask, close. This is the only place where the lifetime is implicit - precisely because it is entirely contained within the call. Nothing survives the return. ## `run` *function* ```typescript export async function run(agent: Agent, task: string, options: RunOptions = {}): Promise { /* … */ } ``` Runs one task with a throwaway subagent. The lifetime is forced to `"task"`: an agent whose frontmatter declares `lifetime: workflow` gains nothing from persisting across a single turn. Use {@link spawn} when the memory must outlive the call. The session is closed even if the turn fails or is cancelled. ## `RunOptions` *type* ```typescript export type RunOptions = Omit & AskOptions & { /** Defaults to the real {@link spawn}, like every combinator's. */ spawn?: SpawnFn; }; ``` {@link SpawnOptions} without `lifetime` - `run` is `"task"` by definition - plus the per-turn deadline.
