When building AI Agents, developers often need to provide callable tool (function) definitions for large language models (LLMs). These definitions are usually presented in JSON Schema format, describing the tool's parameters, types, and purposes. However, manually writing and maintaining these Schemas is both tedious and error-prone, especially when the number of tools increases or parameters change.
For Dart developers, this problem is particularly prominent. As a strongly typed language, Dart's type system should naturally provide advantages for Schema generation, but in the past, there was a lack of an automated tool that could fully leverage this advantage. tool_schema_generator was born precisely to address this pain point.
