Subagent Creator

This is the meta-skill for building subagents, the specialized AI assistants that run in isolated contexts when your main agent needs to delegate complex work. You'd use it when you need a verifier to validate completed tasks, a debugger to hunt down root causes, or a security auditor to review sensitive code. The guide emphasizes that the description field is critical because it determines when automatic delegation happens, and it walks you through the frontmatter setup, prompt structure, and common patterns like code reviewers and validators. If you're building workflows where different specialized perspectives matter more than raw context accumulation, this shows you how to architect that separation properly.

Subagent Creator

This skill provides guidance for creating effective, agent-agnostic subagents.

What are Subagents?

Subagents are specialized assistants that an AI agent can delegate tasks to. Characteristics:

Isolated context: Each subagent has its own context window
Parallel execution: Multiple subagents can run simultaneously
Specialization: Configured with specific prompts and expertise
Reusable: Defined once, used in multiple contexts
