Salesforce Ai Research introduces walts (Web agents that learn tools): enabling LLM agents to automatically discover smooth tools on any website

The Salesforce AI research group presented Wall (Web agents learning tools), a framework for back-end developers of the website used in non-renewable non-renewable tools. It means browser switching tools that can't complain rather than long chains of clicks. Agents then call functions such as search, filter, sort, post_commentagain create_listing. This reduces the dependency on the large language model for step-by-step reasoning and increases the decision-making process at execution time.

What did Walt build?

Web agents tend to fail when architectures change or when tasks need to be sequenced over a long period of time. Walt looks at this mode of mining offline mining, and presents it as tools that help navigation, selection, extraction, and selection steps. Tools manage contracts in the form of Schemas and models. During startup, the agent executes a short program with several tool calls to complete the task. The goal is to create a high-achieving composition with fewer steps and less reliance on free-form thinking.

Pipe in two sections

Pipeline can be found and built with verification. At Discovery, Walt evaluates a website and proposes tools that will integrate with tools that will perform common goals such as discovery, content management, and communication. In construction and verification, Walt converts traces into deterministic documents, tests fasts, attempts to increase the URL when possible, extracts the installation schema, and registers the tool after the end of the end. This shifts as much work as possible to stable URL and form functionality and leaves a foundation for the truly demanding cases.

Results on visuwebarena and webarena

In visuwebarena, Walt ​​reports an average success rate of 52.9 percent with the results of dividing by 64.1 percent to 54.4 percent in purchases, and 39.0 percent in Reddit. The table lists foundations such as SGV at 50.2 percent and direct at 33.7 percent. Human performance is 88.7 percent on average.

In webarena, Walt averages 50.1 percent in gitlab, map, shopping, CMS, reddit, and miscellaneous. The table shows Walt before the previous methods with a Pie Point Margin over the basis of the import of skills. Human performance is 78.2 percent.

Performance and bankruptcy

Tools reduce the action count by a factor of about 1.4 on average relative to a simulated agent without tools. In Classifieds split, abrasions show consistent benefits when tools are used across various agents back. WALT with GPT 5 MINI records a high 7 percent and 27 fewer steps, while the human display strategy shows a success of 66.0 percent. The fully autonomous walt reaches 64.1 percent with 5 percent fewer steps than the case of human exposure. Multimodal DOM Parsing adds an overall improvement of 2.6%. External verification adds 3.3 percent while increasing checks. Across the board, Walt records 21.3 percent less than basic policies.

Design decisions that force determines

Walt prefers URL-level functionality when the site displays query parameters or search and filter methods. When pages need to be dynamically activated, a Tool script is inserted to include automated steps such as content extraction or waiting for page load. Selected Authentication and schema validation reduces traffic when changing sites. This approach keeps part of the agent's work down to the set of tools found and the search for decisive actions such as submitting, entering, and clicking.

Key acquisition

1. Get closerWalt discovers and validates the functions of the website, and presents them as expensive tools with installation schemas, selected stability, URL optimization, reducing the sequence of brittle steps in the prescribed operation.
2. Results – Visuolwebarena: An average success rate of 52.9%, with 64.1% in Classifieds, 53.4% ​​in shopping, and 39.0% in Reddit, from several articles reported in the paper.
3. Results – webarena: Average success rate of 50.1% across gitlab, map, shopping, CMS, reddit, and more, showing a consistent benefit over skill import and search-based basics.
4. Performance and bankruptcy: Making the tool reduces steps by about 1,4x, with 21,3% fewer actions on average. Multimodal DOM Parsing adds + 2.6% Overall success, and external validation adds + 3.3%.

WALT is a useful pivot from the step-by-step process of installing installed tools. The framework returns latent website developers to work on non-renewable tools for discovery, content management, and communication. By encouraging the UI trace in the Schema determination and validation tools and URL Operations, Walt raises the success of the Web Agent to 50.1 percent in webarena and webarena, while cutting actions by about 21.3 percent. The output is sent by the CLI, walt discover, walt agentand MCP working in conjunction.
