• I included enough detail to reproduce or investigate the problem.

Area

apps/desktop

Steps to reproduce

I'm on an ultrawide high resolution monitor (Odyssey G9 57" 7680 × 2160) and the font size for the tool calls is extremely tiny and difficult to read. I see there are ways to control the font size in various other typographies but nothing for the tool calls in the chat themselves.

Expected behavior

Expose a tool call font size or just reuse one of the existing fonts for tool calls as well.

Actual behavior

See screenshots. Fonts are ridiculously small for tool calls.

Impact

Minor bug or occasional failure

Workaround

I can scale the entire interface larger (Cmd-+) and shrink the Interface, Prompt, and Terminal fonts accordingly to make the tool call font relatively bigger compared to the other fonts.
