Subagents
Subagents are specialized AI assistants that handle specific types of tasks. Each runs in its own context window with a custom system prompt, specific tool access and independent permissions.
Use one when a side task would flood your main conversation with search results, logs or file contents; the subagent does the work and returns a summary.
Several vendor plugins bundle subagents, such as a database or deployment specialist, so Claude Code can delegate service-specific work.
