- In cross-website skill transfer, ASI effectively reuses common skills and updates incompatible ones to adapt to website changes.
Significance
The ASI method is significant in academia and industry as it addresses the inefficiency of agents in diverse web environments, significantly improving task success rates and efficiency through the verification and reuse of programmatic skills.
Technical Contribution
ASI introduces the concept of programmatic skills, offering higher verification and composability compared to existing methods. By representing skills as executable programs, ASI achieves more efficient task planning and execution.
Novelty
ASI is the first to introduce programmatic skills to agent tasks, differing from previous text-based methods by providing higher verification and execution efficiency.
Limitations
- In some complex websites, programmatic skills may not fully adapt to all changes, leading to decreased efficiency.
- The skill induction process relies on high-quality initial data, which may limit its application in data-scarce domains.
Future Work
Future research can explore the application of ASI in more complex web environments and how to further enhance the efficiency and accuracy of skill induction.

Plain Language Accessible to non-experts
Imagine you are cooking in a kitchen. You need to prepare ingredients, cook, and plate the food. Traditional methods are like learning how to chop and fry every time. The ASI method is like having a cookbook that guides you step-by-step through the entire process. This way, you can complete tasks faster and better because you don't have to learn from scratch each time. Programmatic skills are like this cookbook, helping agents efficiently complete tasks in web environments.

Abstract
To succeed in common digital tasks such as web navigation, agents must carry out a variety of specialized tasks such as searching for products or planning a travel route. To tackle these tasks, agents can bootstrap themselves by learning task-specific skills online through interaction with the web environment. In this work, we demonstrate that programs are an effective representation for skills. We propose agent skill induction (ASI), which allows agents to adapt themselves by inducing, verifying, and utilizing program-based skills on the fly. We start with an evaluation on the WebArena agent benchmark and show that ASI outperforms the static baseline agent and its text-skill counterpart by 23.5% and 11.3% in success rate, mainly thanks to the programmatic verification guarantee during the induction phase. ASI also improves efficiency by reducing 10.7-15.3% of the steps over baselines, by composing primitive actions (e.g., click) into higher-level skills (e.g., search product). We then highlight the efficacy of ASI in remaining efficient and accurate under scaled-up web activities. Finally, we examine the generalizability of induced skills when transferring between websites, and find that ASI can effectively reuse common skills, while also updating incompatible skills to versatile website changes.
