Summary of Changes

Hello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refines the user interface by enhancing the 'Ask Question' dialog's ability to display extensive content and by optimizing the rendering of tool outputs. The changes ensure that the UI adapts better to different terminal sizes and handles the display of various tool states, including hidden or ongoing operations, with greater precision and visual clarity.

Highlights

  • Ask Question Dialog Height: The 'Ask Question' dialog now dynamically adjusts its height to accommodate long questions, removing a previous 15-line display limit in tall terminals.
  • Tool Group Rendering Logic: Improved the rendering logic for tool groups to prevent spurious lines and phantom boxes, especially when dealing with hidden tools (e.g., in plan mode) or ongoing agent activity. This ensures a cleaner and more accurate display of tool outputs.
  • Hidden Tool Visibility: Refactored the visibility determination for pending tool calls, leveraging a new shouldHideToolCall utility. This correctly hides tools like in-progress 'AskUser' tools and plan-mode write/edit operations from the main tool group display, as they are handled by other UI components.
  • New Regression Tests: Added a dedicated regression test file for ToolGroupMessage to cover various scenarios, including the suppression of phantom tool groups, spurious bridge groups, and correct border rendering for agent states.

Code Review

This pull request refactors the rendering logic for tool groups and dialogs within the CLI UI. Key changes include updating the AskUserDialog to allow questions to exceed previous line limits in tall terminals and refining the visibility logic for tool calls using a new shouldHideToolCall utility. The changes also introduce comprehensive regression tests for ToolGroupMessage to address issues with phantom tool groups, spurious bridge groups, and correct border rendering for agents. Snapshot tests for ExitPlanModeDialog and MainContent have been updated to reflect these rendering improvements, particularly for hidden lines in plan mode. A review comment points out a potential issue in ToolGroupMessage.tsx where the bottom border for an empty tool group might render spuriously if it's not explicitly closing an existing box, suggesting a refinement to the rendering condition.

The logic for rendering the bottom border of an empty tool group (a "closing slice") appears to be incomplete. It currently renders a bottom border if borderBottomOverride is not false, without considering if it's a continuation of a previous box (i.e., if borderTop is true).

This can lead to spurious horizontal lines in the UI when an empty tool group is rendered without a preceding open box. The new regression test Plan Mode: suppresses spurious bridge group (empty, no top border) seems designed to catch this, but the current implementation would still render a border.

The condition should be strengthened to only render the border for an empty group if it's meant to close an existing box, which is indicated by borderTopOverride being true.
