Interactive builder for Claude Code subagents (agent files with YAML frontmatter and an XML-sectioned Markdown body). Use it to create, scaffold, design or add a subagent, specialist agent, reviewer agent or persona, or to ask how to write an agent file, even when the user only describes the job ("I want an agent that triages CI failures").
