July 2026: VS Code extension improvements for kilocode focused on the @-mention file picker. Delivered a UX- and test-focused reordering that prioritizes file search results over the 'Browse files...' option, moving the file picker result to the end to make the closest match the default. Included corresponding unit test updates to reflect the new ordering. Addressed the ordering change introduced in buildMentionResults with fixes that ensure the closest matching file is selected by default while keeping 'Browse files...' available at the bottom. The changes are implemented via two commits and align with user expectations and product goals for faster, more reliable file referencing. Key contributions: - Prioritized file search results in the @-mention dropdown and updated tests (commit 751cac5e757d626c66e66122ffce312cc4182a29). - Corrected the ordering so FILE_PICKER_RESULT appears after file results, ensuring the closest match is the default; tests updated (commit 47d395726951fb92138276e8be455545c157537d). - Fixed tests for use-file-mention ordering to reflect new behavior. Impact and value: - Faster, more accurate file selection in the extension, reducing clicks and friction for developers. - Improved test reliability and coverage for highlight features in the VS Code integration. - Demonstrated proficiency with TypeScript, VS Code extension APIs, and unit testing practices.
