Worked on documentation and schema validation across two repositories, focusing on clarity and data integrity. In Jeffallan/claude-skills, improved documentation by refining argument-hint formatting in COMMAND.md and correcting links and structure in README.md, which enhanced readability and accessibility for contributors. In modelcontextprotocol/modelcontextprotocol, implemented a maximum length constraint for array values in both CompleteRequest and CompleteResult schemas, using JSON Schema and TypeScript to enforce data validation at the API boundary. Demonstrated technical writing, Markdown, and schema validation skills, delivering targeted improvements that reduced onboarding friction and improved the reliability of data passed through the system without introducing new bugs.
