EconSkills is a skill library and evaluation framework that transforms verified EconWebArena trajectories into parameterized standard operating procedures for retrieving live economic data. Each skill captures scope, navigation steps, site-specific guidance, verification checks, and recovery steps, replacing instance-specific values with placeholders. The framework evaluates skill transfer to new tasks and the effectiveness of library retrieval, showing that matched skills improve success rates and reduce steps compared to no-skill prompting, while abstraction outperforms raw trajectory replay. At scale, retrieval performs competitively overall, excelling on directly covered tasks and compensating for uncovered tasks through approximate matches.

arXiv:2608. 06880v1 Announce Type: new Abstract: General-purpose skills promise reusable procedural knowledge for language agents, yet semantic relevance does not guarantee execution utility: a retrieved skill may encode assumptions that conflict with the current task, execution environment, or other retrieved skills.
LLM agents increasingly execute long-horizon tasks through tool use and environment interaction, shifting evaluation from final-response scoring to verification of complete executions. For skill-augmented agents, verification additionally requires the procedural knowledge encoded in task-time skills, because this knowledge indicates what evidence to inspect and which failures are task-critical.

SCAFFOLD is a self‑improving framework for visual web agents that automatically induces parametric, executable skills from successful trajectories and organizes them into a recursively composed hierarchy. It compresses the skill library using a minimum‑description‑length criterion and behavioral equivalence checks, and periodically distills these skills back into model weights to internalize the abstractions. Experiments on WebArena, VisualWebArena, and Online‑Mind2Web show that SCAFFOLD raises success rates by 11.1–17.2 absolute points over the best skill‑augmented baseline and continues to improve across five self‑improvement iterations without collapsing the library.
