Show HN: Reverse-engineering web apps into agent tools

A browser-based agent runs inside an authenticated web app, monitoring how the app calls its own APIs, and automatically converts this into tools for agents.

This technique focuses on solving the problems of the existing computer-use (screen-clicking) approach, namely its slow speed, high token consumption, and lack of API standardization. The generated tools are stored in the form of a 'Recipe' that includes the following information.

• API endpoints and methods
• Authentication method (JWT, cookies, how to obtain refresh tokens, etc.)
• Response and input schemas
• Natural language description of the function

This approach has the advantage of not requiring any modification or maintenance of the app's source code, and even if the API structure changes, the agent can relearn it and update automatically. This allows AI agents to perform direct actions on behalf of users even in complex services such as Jira and Spotify.
