Feature request: expose @file mention (and slash-command) highlighting as customizable theme tokens
What
In the prompt input box, slash commands like /foo are syntax-highlighted (blue), but @file mentions like @CLAUDE.md render as plain text with no highlight. Neither color is currently exposed in the theme system.
The documented input-related theme tokens only cover the input box border and mode indicators (promptBorder, planMode, autoAccept, bashBorder), the autocomplete suggestion color, and the global text color — none of which let you style @file references distinctly from the rest of the typed text.
Request
Please add customizable theme tokens for prompt-input syntax, e.g.:
atMention/fileReference— color/style for@filereferences typed in the promptslashCommand— expose the (currently hardcoded) slash-command highlight color so it can be themed too
Why
@file references are an important part of composing prompts, but they currently blend into normal text, making them hard to spot while typing — especially in long prompts that mention several files. Slash commands already get a distinct color; @ mentions deserve the same treatment, and exposing both as theme tokens would let users tune them to their palette via /theme.
