VS Code's sub-agents enable parallel execution and context isolation for AI-powered development tasks. Sub-agents are independent agent loops with their own context windows that handle specialized tasks like code research, security reviews, or architecture analysis, then return summarized results to the main agent. This prevents context window bloat and enables parallel processing. Custom agents can be created with specific models, workflows, and tool access, making them ideal for deterministic, repeatable tasks. The approach allows developers to optimize for speed and cost by assigning faster models to routine tasks and more powerful models to complex planning or review work.
