CopilotKit launches CLiF: turning real user work into agent skills, evals and fine-tuning data

techNmak · x · 2026-10-14

CopilotKit released CLiF (Continual Learning from Full-Stack Trajectories) in early access. Built on the AG-UI protocol — an open bidirectional protocol between agents and user-facing apps adopted by Google, Microsoft and AWS — CLiF captures both what agents and users did, converting real product usage into skills, evals and fine-tuning data. The team argues evals are today's most expensive problem, and notes CLiF is fully self-hostable with exportable outputs.
