Sub-Agent Coordinator

Orchestrate focused work across multiple sub-agents using proven patterns. This skill handles briefing, spawning, communication, and verification when delegating complex tasks.

Use this skill to parallelize independent work, avoid conflicts, and maintain coordination state across sub-agents.

Framing — sub-agent coordination is harness engineering for delegated work. Each primitive shows up here explicitly: context engineering lives in the briefing templates (what the sub-agent sees before it starts); observable feedback loops live in the verify-before-completion gate and structured-result contracts; state preservation is why all spawning happens at the parent level (no nested sub-agents) — nested state is unrecoverable. When a sub-agent run fails, ask which primitive was underspecified before asking whether the sub-agent was "wrong."

What Are Sub-Agents

Sub-agents are separate agent instances that handle a scoped piece of work. They:

• Work independently on assigned tasks
• Operate within defined constraints and boundaries
• Report back with structured results
• Can be spawned in parallel for independent tasks

A sub-agent is not a human teammate — it is another instance of you, task-focused and context-limited, designed to parallelize work that would otherwise be sequential.
