[Bug]: Long descriptions in the composer / command menu are truncated with no way to read the full text #26940

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/web

Steps to reproduce

1. In a thread, type / in the composer to open the command menu.
2. Find an entry whose description is longer than the row, for example a provider command or skill with a long description.
3. Hover the row, or highlight it with the keyboard.

Expected behavior

Hovering or highlighting a row lets me read the whole description. For example, the text scrolls or animates horizontally, the active row expands or wraps, or a tooltip shows the full text.

Actual behavior

The description is cut off with an ellipsis and nothing reveals the rest, so you cannot read what the command does. For example /code-review ends in "(plus reuse/simpli…" and /ultrareview ends in "Runs in a …".

In the code (upstream/main @ 6d450a4), ComposerCommandMenu.tsx renders the description as a plain truncated span:

<span className="min-w-0 flex-1 truncate text-left text-secondary-label text-xs">
  {props.item.description}
</span>

(apps/web/src/components/chat/ComposerCommandMenu.tsx, line 242). The row has no title, no tooltip, and no hover or active-state handling for the description. onMouseMove only sets the highlighted item. A search of apps/web/src found no marquee or text-scroll style that could be reused.

Impact

Minor bug or occasional failure

Version or commit

Code references: upstream/main @ 6d450a4. The screenshot is from a locally running T3 Code; I did not record its version.

Environment

T3 Code web UI; the server runs on Linux (WSL2). Client OS and browser or desktop shell not recorded.

Logs or stack traces

No response

Workaround

None found for the full text apart from reading the provider's own documentation for the command.
