Tool development framework requirements
ReCall enables tool extensions through standardized interface protocols, and developers need to implement three core components:
1)Input and output specifications: Explicitly define the JSON Schema format of the tool
2)Execution Logic Implementation: Real-world functionality in Python classes
3)Error handling mechanism: return standardized error codes and alert messages
Development Sample Flow
- Create a new tool class in the tools directory, inheriting from the BaseTool base class
- realization
execute()Methods to encapsulate core functionality - Registering tool metadata in config/tools.yaml
- Verify tool usability with test scripts
Best Practice Recommendations
To ensure the quality of the tools:
1) Suggest adding type annotations to enhance maintainability
2) Complex tools should include unit testing
3) Recommended to use FastAPI to encapsulate web services
4) Pay attention to thread safety and high concurrency scenario optimization
