Worked on the tc39/agendas repository to establish a structured planning process for language design discussions, focusing on the goal of consensus through effective layering. Developed and documented a planning item that outlined a 60-minute design session, including presenter details and supporting slides, all captured in Markdown to ensure clarity and accessibility. Emphasized documentation as a core skill, standardizing how future language design goals are proposed and reviewed within the repository. This work improved process alignment and facilitated smoother handoffs for upcoming design decisions, laying a foundation for more organized and transparent collaboration among contributors using Markdown and documentation best practices.
