FlashScript turns repeated agent runs into fixed, reusable programs

A compiled program is a workflow the human has approved in fixed form. Designing the moment of compilation, and the moment of revocation, is the product work FlashScript leaves on the table.

Machine summary of the source

FlashScript is a research system that watches an AI agent complete a task, then compiles that run into a fixed, deterministic program. The next time the same task arrives, the system runs the program rather than asking the agent to reason from scratch. Repeated work becomes faster, cheaper, and more consistent. The research tests this on real workflows and shows that compiled programs match or beat open-ended agent runs on accuracy. The human benefit is predictability: a workflow you have approved once behaves the same way the next time. You no longer have to wonder whether the agent will take a different path through familiar territory. For designers, the tension is between flexibility and trust. An open-ended agent can adapt; a compiled program cannot. The system surfaces a real design question: at what point does a recurring workflow earn the right to run without fresh reasoning, and who decides when that threshold is crossed?
