Problem

In the IDE sidebar, the chat view was sized to the entire editor window
instead of the panel. Long code blocks / terminal output pushed the view past
the panel edge with no way to scroll — content was just clipped.

Caused by viewport-sized units inside a sidebar webview:

  • w-screen (100vw) on the chat root (gui/src/pages/gui/index.tsx)
  • height: 100vh + overflow-x: visible on the layout grid (Layout.tsx)
  • max-width: calc(100vw - 24px) on code/terminal <pre> blocks
  • missing min-w-0 on the flex main element (flexbox min-width trap)

Fix

  • pages/gui/index.tsx: w-screen → w-full, add min-w-0 to <main>
  • Layout.tsx GridDiv: height: 100vh → 100%, overflow-x: visible → hidden
  • StyledMarkdownPreview / UnifiedTerminal: pre max-width calc(100vw - 24px) → 100%
    (existing overflow-x: scroll now works against the panel width)
  • Bump extension version to 2.2.2

Verification

  • tsc --noEmit: clean on all touched files
  • vitest run UnifiedTerminal.test.tsx renderedHistory.test.ts: 25/25 pass
  • vite build + GUI copied into extensions/vscode/gui/: bundle contains min-w-0, zero w-screen/100vw occurrences
  • Tested in VS Code (F5 dev host): chat resizes with the panel, long lines scroll inside code blocks

Fixes the view-overflow issue reported in the orchestrator-status work.

Summary by CodeRabbit

  • Bug Fixes

    • Improved GUI layout sizing to prevent horizontal overflow and ensure content fits within its container.
    • Updated code block and terminal previews to remain within the available width.
    • Refined the main interface layout for more reliable rendering alongside the history sidebar.
    • Improved responsive behavior across different window and content sizes.
  • Chores

    • Updated the VS Code extension version to 2.2.2.

🔵 Needs a closer look

package-lock.json still records version 2.2.1 and must match the manifest’s 2.2.2 version.

extensions/vscode/package.json:5

  • The extension manifest is now 2.2.2, but the tracked extensions/vscode/package-lock.json still declares the root package as 2.2.1 (both its top-level and packages[""] version). Please regenerate/update the lockfile with this version bump so installs and packaging do not carry inconsistent extension metadata.
  "version": "2.2.2",

Comment thread gui/src/components/Layout.tsx
The chat root used w-screen (100vw) and the layout grid used height: 100vh,
so in the IDE sidebar the view was sized to the whole editor window instead
of the panel. Combined with a missing min-w-0 on the chat main element and
max-width: calc(100vw - 24px) on code/terminal <pre> blocks, long content
pushed the view beyond the panel with no way to scroll it.

- pages/gui/index.tsx: w-screen -> w-full, add min-w-0 to <main>
- Layout.tsx GridDiv: height 100vh -> 100%, overflow-x visible -> hidden
- StyledMarkdownPreview/UnifiedTerminal: pre max-width calc(100vw-24px) -> 100%
  (existing overflow-x: scroll then works against the panel width)
