What you'll learn
Understanding subagents versus skills in Claude Code
Learn why subagents run in a fresh context window while skills work inside your main session.
Creating a custom subagent with the agents command
Learn to use /agents to build a custom subagent, choose its scope, tools, and model
Writing descriptions that trigger the right agent
Learn to write precise YAML descriptions so Claude Code invokes the right agent automatically.
Knowing when a task actually needs a subagent
Learn to spot tasks that dump output you will never reread and hand those off to an agent.
Why this topic matters
Most people treat Claude Code as one long chat and let every file dump and research pass sit in their main context. That fills the window fast and slows Claude down. Subagents run in their own clean session, can use a cheaper model like Haiku, and report back only the result, so your main session stays focused and your token bill stays lower.
