Skill2Env: Capability-Oriented Environment Synthesis from Skills for General Agents
Skill2Env turns written skills into executable agent-training environments, then hardens them using solver traces.
The paper frames skills as useful but incomplete: they hold procedures and tool-use knowledge, not full tasks with runnable environments. Skill2Env converts a source skill into blueprints with objectives, constraints, environment facts, acceptance criteria, and rubric evaluators. Its Iterative Task Hardening step uses execution evidence to find tasks that are too easy and revise them. The authors report that supervised fine-tuning on 1.5K high-scoring trajectories from these environments improved results across agent benchmarks. HF Daily Papers' note
