[DOCS] /theme documentation missing "Auto (match terminal)" theme option

Documentation Type

Missing documentation (feature not documented)

Documentation Location

Section/Topic

/theme command entry and theme picker options

Current Documentation

The docs currently say:

/theme — Change the color theme. Includes light and dark variants, colorblind-accessible (daltonized) themes, and ANSI themes that use your terminal's color palette

And the keyboard shortcuts page currently says:

Ctrl+T — Toggle syntax highlighting for code blocks Only works inside the /theme picker menu. Controls whether code in Claude's responses uses syntax coloring

Neither page documents the new "Auto (match terminal)" theme option or explains that it follows the terminal's dark/light mode.

What's Wrong or Missing?

Claude Code v2.1.111 added an "Auto (match terminal)" theme option that users select from /theme, but the docs do not describe that option anywhere.

The current /theme documentation lists broad theme categories, but it does not tell users that Claude Code can automatically match the terminal's dark/light mode. That makes the new option hard to discover and leaves users without any explanation of what "Auto" does.

Suggested Improvement

Update the /theme documentation to add the new Auto option explicitly.

Suggested additions:

• In https://code.claude.com/docs/en/commands, expand the /theme entry to mention an Auto (match terminal) option.
• Briefly explain that this option follows the terminal's current dark/light appearance instead of requiring a fixed light or dark theme selection.
• If there is a dedicated description of the theme picker UI, list the available theme categories there as well so users can understand when to choose Auto versus a fixed theme.

Impact

Medium - Makes feature difficult to understand
