Worked on enhancing the anthropics/anthropic-sdk-python and anthropics/anthropic-sdk-typescript repositories, focusing on API development and integration using Python and TypeScript. Delivered performance improvements by adding a 'speed' parameter to the Messages API’s count_tokens method, enabling more flexible token counting in synchronous workflows. Developed conversion helpers for Model Context Protocol tools, prompts, and resources, streamlining integration with the Anthropic SDK and improving error handling and resource management. Updated documentation and branding by refining the README badge color for better visibility and consistency. Emphasized backend development, asynchronous programming, and clear documentation to improve developer experience and business value.
