Worked on stabilizing the Cut Tool within the Unity-Technologies/com.unity.probuilder repository, focusing on a critical edge-case involving two vertices placed on the same edge. Addressed a crash scenario by refining the tool’s logic to prevent unintended face creation, thereby improving reliability and user experience for designers. Utilized C# and leveraged Editor Scripting alongside the ProBuilder API to implement and validate the fix. Updated documentation and changelogs to ensure transparency and maintainability across the codebase. This targeted bug fix reduced editor crashes and reinforced the stability of the ProBuilder toolset, supporting smoother workflows for Unity development teams.
