These products offer packaged skills, capability libraries, and auditing tools designed to expand what AI agents and assistants can do. They are built for AI developers and agent creators who need domain-specific functionality like music composition, data visualization, or research analysis. Unlike general agent orchestration platforms, this cluster centers on discrete, plug-and-play skills and prompt-driven agent actions.
