Forsy is a platform and open-skill ecosystem that captures AI agent workflows as structured, annotated traces and enables exchange of real-world agent work experience. It provides a trace schema and tooling to record task context, step-by-step traces, tool usage, observations, internal reasoning signals, human feedback, failures, retries, artifacts, and outcomes. By turning completed agent workflows into inspectable process data, Forsy supports evaluation, reproducibility, post-training research, and experience transfer between agents and teams.
