Worked on enhancing the documentation for the Signal interface within the streamich/tldraw repository, focusing on improving clarity and maintainability for developers integrating with the @tldraw/state package. The primary contribution involved correcting typos in the lastChangedEpoch property comments, which reduced the risk of misinterpretation and streamlined the onboarding process for new contributors. Leveraged TypeScript and strong documentation practices to ensure that the API surface was accurately described, supporting better developer experience and reducing potential support overhead. The work emphasized attention to detail and a commitment to clear communication, contributing to the overall quality and usability of the codebase.
