Claude Code Subagents
Define specialised helper agents with their own prompts, tools and context.
About
Subagents are reusable assistants that Claude Code can delegate to — a code reviewer, a test runner, a researcher. Each has its own system prompt, tool permissions and context window, and lives as a Markdown file in your project or user settings. The way to stop your main agent's context getting polluted by side quests.
