Subagent Development

About

Acts as the central authority for creating, configuring, and managing Claude Code subagents. This skill guides developers through the entire subagent lifecycle, including agent file formats, YAML frontmatter, tool access, model selection, and programmatic creation via the Agent SDK. Its core principle is to delegate 100% of queries to the `docs-management` skill, ensuring all guidance is based exclusively on the latest official documentation. Use this skill for any task involving subagents, from initial creation and configuration to advanced troubleshooting and optimization.
