Worked on the modelcontextprotocol/typescript-sdk repository to enhance documentation around stateless HTTP endpoint behavior, focusing on clarifying the semantics of GET and DELETE requests. Used Markdown to provide precise inline README comments, explaining that GET returns a 405 error due to the absence of SSE notification support and that DELETE does not terminate sessions in a stateless context. This documentation update aimed to reduce confusion for SDK users and lower support overhead by aligning endpoint expectations with actual runtime behavior. The work emphasized clear communication and improved API discoverability, leveraging strong documentation skills to support developer onboarding and usage clarity.
