Cross File Remote Execution Context

Source spawns a local helper that also contains network and dynamic execution context; review data flow before blocking.

2 * Subagent Tool - Delegate tasks to specialized agents

3 *

4 * Spawns a separate `pi` process for each subagent invocation,

5 * giving it an isolated context window.

6 *

7 * Supports three modes:

8 * - Single: { agent: "name", task: "..." }

9 * - Parallel: { tasks: [{ agent: "name", task: "..." }, ...] }

10 * - Chain: { chain: [{ agent: "name", task: "... {previous} ..." }, ...] }

11 *

12 * Uses JSON mode to capture structured output from subagents.
