Luoxin Luo enhanced the modelcontextprotocol/registry repository by improving its documentation to clarify the location of the OpenAPI specification. Focusing on Markdown and documentation best practices, Luoxin updated the project structure description to explicitly state that the api/ directory contains the OpenAPI spec. This targeted change addressed a common onboarding challenge, making it easier for developers to discover and understand the API-first organization of the codebase. While the work was limited in scope, it demonstrated attention to developer experience and maintainability. The update did not involve code or bug fixes, but contributed to clearer project navigation and faster team onboarding.
