Subagent
A separate helper that works for Claude, with its own working memory. It gets a task, does it off to the side and returns only the conclusion, like a colleague sent to the archive.
How it appears in the course
A subagent is a “helper Claude”, which the main Claude sends off to do a particular job.
The main Claude delegates a task to the subagent (that is, hands it over to be done). The subagent works on its own “workbench” and sends back only the final result.
You save context. Searching through 200 files happens in the subagent’s context. All that reaches you is a short conclusion.
