Plain Language Accessible to non-experts
Imagine you're cooking in a kitchen. Each dish has a recipe that tells you what ingredients you need, the steps to follow, and the precautions to take. Skill creation is like creating recipes for AI agents. The RWSA intermediate representation is like breaking down the recipe into a list of ingredients, step-by-step instructions, and precautions. The W2S framework is a smart assistant that can automatically generate new recipes from your past cooking experiences. This way, AI agents can reuse these recipes in different scenarios, ensuring they always make delicious dishes.

Abstract
Large language model agents increasingly rely on Skills to encode procedural knowledge, yet high-quality Skills remain costly to hand-write. This paper studies automatic Skill construction from heterogeneous interaction evidence, including demonstrations, agent trajectories, tool traces, and execution logs. We argue that trace-to-skill construction is not simple summarization tasks, because traces are fragmented, redundant, and may miss rare but safety-critical behaviors. To address this, we introduce RWSA, a workflow-oriented intermediate representation that decomposes Skills into Workflow structure, execution Semantics, and runtime Attachments, capturing task decomposition, control flow, verification, safety, rollback, and state management. Building on RWSA, we propose W2S, a framework that segments traces, induces local Skill drafts, aligns shared structures, reconciles branches, and compresses redundancy while preserving evidence and confidence annotations. Experiments on 70 Skills show that W2S improves behavioral replay consistency by 10.5% over summarization- and prompting-based baselines, highlighting the need to treat traces as executable runtime specifications rather than compressible text.
