   We identified the reason: a lack of understanding about JSON schema and insufficient compiler-level support. Agent frameworks should strengthen fundamental computer science principles rather than focusing on fancy techniques.

5. Laravel

   4 440 84,706 8.9 Blade

   Laravel is a web application framework with expressive, elegant syntax. We’ve already laid the foundation for your next big idea — freeing you to create without sweating the small things.

   

   If you're planning to convert a backend server to an AI agent using function calling, avoid languages and frameworks that require developers to manually write JSON schemas, such as PHP Laravel and Java Spring RestDocs.

6. langchain

   5 98 142,054 10.0 Python

   The agent engineering platform.

   

   But what about today? Has function calling conquered the world? No—rather than function calling, agent workflow-driven development has become dominant in the AI development ecosystem. langchain is perhaps the most representative framework in this workflow ecosystem.

7. openapi

   Discontinued OpenAPI definitions, converters and LLM function calling schema composer. (by samchon)

   Below is demonstration code that converts a shopping mall's OpenAPI document to a function schema, plus a video showing it running as an actual AI agent. Simply by importing the swagger.json file from an existing shopping mall server, you can search for products through chat, purchase them, manage delivery, apply discount coupons, or process refunds.

    Instead, use compiler-driven (or reflection-based) OpenAPI document generators like Nestia or FastAPI. Then convert the compiler-generated OpenAPI to a specific AI function schema using the @samchon/openapi library, as shown below.

    FastAPI framework, high performance, easy to learn, fast to code, ready for production

    Discontinued Automatic view component renderer by AI agent [GET https://api.github.com/repos/wrtnlabs/autoview: 404 - Not Found // See: https://docs.github.com/rest/repos/repos#get-a-repository]

    

    Also, if you want to make specific visual components for each function, but you don't have enough time, consider using our another framework AutoView which can generate TypeScript frontend code from schema information.
