Plus a visual builder that compiles to LangGraph, CrewAI, Mastra, or MS Agent Framework. Meet Aielia, she answers a quick question in one step, and stops for your approval before she sends an email, pays an invoice, or runs a command. A harness is the governance and reliability control plane around an autonomous agent, the agent proposes, the harness decides what happens next.
