Worked on developer experience improvements for the MystenLabs/sui repository by enhancing documentation related to JSON parameter handling. Focused on clarifying how to pass parameters of type Option<Move Type> via JSON for both JSON RPC and sui client calls, the work involved updating Markdown-based documentation and restructuring tables to explicitly include Option<Move Type> alongside Vector<Move Type>. This targeted update aimed to reduce onboarding friction and minimize usage errors by making parameter requirements more discoverable and traceable. The changes were tracked through a dedicated commit, demonstrating attention to detail and a methodical approach to documentation and developer support.
