Code Review

This pull request updates the CommandSuggestion.vue component to hide the tooltip when the suggestion panel is closed and improves the readability of command descriptions in dark mode by adjusting their text color. A review comment suggests extending the watcher to also monitor changes in the commands list, which prevents "ghost" tooltips from remaining visible when items are dynamically filtered out of the DOM.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Hey - I've left some high level feedback:

• The watch on props.visible directly mutates tooltip.visible, introducing two sources of truth for visibility; consider deriving tooltip.visible from props.visible (or a single reactive state) to avoid potential inconsistencies.
• The updated dark-mode color #e0e0e0 is hard-coded; if you have a design token or CSS variable system for theming, it would be more maintainable to reference that instead of a literal color value.
