In February 2025, Jose Cerqueira delivered a focused documentation update for the MystenLabs/sui repository, addressing on-chain randomness resource limits. He enhanced developer guides using Markdown and TypeScript, clarifying how to securely access randomness and construct transactions within protocol-defined resource constraints. His work detailed the correct handling of UIDs created and deleted in a single transaction, ensuring accurate resource accounting and reducing integration risk. By referencing protocol configuration and providing explicit usage patterns, Jose improved onboarding and developer experience for randomness integration. The update demonstrated depth in both technical understanding and communication, aligning resource governance with practical developer workflows.
