Claude Code reportedly ships a feature-flagged-off engine that fans out to 1,000 subagents.

Paddo.dev documents a multi-agent orchestration system inside Claude Code where Claude writes a JavaScript orchestration script with a background runtime, holding intermediate state in script variables outside the main context window (paddo.dev). It mirrors orchestrator-worker research architectures. Script-driven, deterministic agent fan-out as a first-class coding pattern is where this is going. The context window stops being the ceiling when state lives in the script.
