add-sdk-method

name	add-sdk-method
description	Use when adding a new method, function, or API endpoint to the SDK. Ensures consistent implementation across all SDKs (Python, TypeScript, Java, Rust CLI) with proper types, tests, and naming conventions.

Add SDK Method

Adds a new method to all SDKs (Python, TypeScript, Java, Rust CLI) with consistent implementation.

Usage

/add-sdk-method <method-name> <description>

Checklist

1. Understand the Method

   • Clarify the method signature (parameters, return type)
   • Clarify the HTTP endpoint it calls (GET/POST/etc, path, body)
   • Clarify error handling requirements

2. Python SDK (python/src/ai_sdk/)

   • Add method to appropriate class (likely AgentHandle in _client.py)
   • Add type hints using Pydantic models
   • Add async version if sync version exists (or vice versa)
   • Add unit test in python/tests/

3. TypeScript SDK (typescript/src/)

   • Add method to AgentHandle class in agent.ts
   • Add TypeScript interfaces to models.ts if needed
   • Add unit test in typescript/tests/

4. Java SDK (java/src/main/java/io/metadata/ai/)

   • Add method to AgentHandle.java
   • Add model classes in models/ if needed
   • Add unit test in java/src/test/

5. Rust CLI (cli/src/)

   • Add subcommand or option to handle the new functionality
   • Update main.rs or relevant module
   • Add unit test

6. Verify

   • Run make lint - all linters pass
   • Run make test-all - all unit tests pass
   • Update CHANGELOG if exists

Patterns to Follow

Python

async def new_method(self, param: str) -> ResponseModel:
    """Short description.

    Args:
        param: Description of param

    Returns:
        ResponseModel with the result
    """
    response = await self._client._request("POST", f"/path/{param}")
    return ResponseModel.model_validate(response)

TypeScript

async newMethod(param: string): Promise<ResponseModel> {
  const response = await this.client.request('POST', `/path/${param}`);
  return response as ResponseModel;
}

Java

public ResponseModel newMethod(String param) throws AISdkException {
    return httpClient.post("/path/" + param, ResponseModel.class);
}

DO NOT

• Add method to only some SDKs (all must be updated)
• Skip tests
• Use different naming conventions across SDKs (camelCase in TS/Java, snake_case in Python/Rust)
• Add dependencies without justification
