Tess enhanced the ethereum-optimism/docs repository by delivering targeted documentation improvements focused on Kurtosis and OP Stack experimentation. She clarified the distinction between Kurtosis as a comprehensive development environment for protocol developers and op-up (localchain.dev) as a lightweight tool for local OP Stack trials. Using Markdown and technical writing skills, Tess updated tutorials to guide users in selecting the most suitable tool for their needs, thereby reducing onboarding friction and potential misconfigurations. Her work provided clearer guidance on tooling and use cases, laying a foundation for faster prototyping and smoother onboarding for new contributors. No bugs were addressed this period.
