What are AI subagents?

Subagents are child AI agents spawned by a parent to handle isolated tasks, returning only summaries to avoid context pollution in the main conversation.

How do subagents work in Swift?

They use a shared agentLoop function with LoopConfig presets: fresh message arrays for children, value semantics for safety, and filtered tools to prevent recursion or state leaks.

Will subagents fix LLM context limits?

Absolutely — by discarding intermediate tool noise, they keep parent contexts lean, letting agents scale deeper without token bloat or instruction decay.
