subagents-meta

What problem does it solve?

Designing, configuring, and managing Claude Code subagents (sub-agents) for specialized tasks, including tool access, model selection, and lifecycle management, requires detailed understanding of their definition and behavior. This skill streamlines subagent orchestration, boosting productivity.

Core Features & Use Cases

• Subagent Creation & Configuration: Guides users through creating agent definition files, configuring YAML frontmatter (name, description, tools, model, permissionMode, skills), and understanding file locations.
• Model & Tool Control: Explains how to select specific models (inherit, sonnet, haiku, opus) and restrict tool access for each subagent, optimizing for cost, performance, and security.
• Lifecycle & Invocation Management: Covers automatic delegation, explicit invocation, agent lifecycle, and session resumption, ensuring efficient agent orchestration.
• Built-in & Programmatic Agents: Provides guidance on using built-in agents like "Plan" and "Explore," as well as integrating subagents programmatically via the Agent SDK.
• Use Case: A developer wants to create a specialized "Code Reviewer" subagent that only has Read and Grep tool access and uses the Haiku model for cost efficiency. This skill provides the exact YAML frontmatter fields and best practices for defining such an agent.
