whitelabel-theme

White-Label Theme Manager

Author one theme, apply it across Claude everywhere. From a single theme JSON, this themes all three surfaces at once: the claude.ai browser UI (a generated Chrome extension), Claude Code terminal colors (~/.claude), and the Warp terminal (~/.warp). No other Claude theming option spans the web UI, the CLI, and the terminal — this is the cross-surface, author-once one.

This plugin is a thin wrapper over the zero-dependency claude-whitelabel-themes CLI, invoked with npx (no global install needed; npx -y fetches it on first use).

Commands

• /apply-theme <id-or-path> — apply a theme everywhere (CLI + Warp + browser extension)
• /list-themes — list the built-in themes
• /preview-theme <id-or-path> [port] — start a local preview server
• /reset-theme — restore defaults (removes the applied CLI/Warp theme)

How to run (for any of the above)

Use the Bash tool to call the CLI, passing the user's argument through:

npx -y claude-whitelabel-themes@^0.1 <command> [args]

For example, applying: npx -y claude-whitelabel-themes@^0.1 apply "<id-or-path>".

After apply: tell the user to re-pick the theme via /theme in Claude Code (or restart) and to reload/restart Warp; for the browser, load the generated extension/ directory via chrome://extensions/ → Load unpacked. After reset: the prior theme is restored. Building a brand-new theme uses npx -y claude-whitelabel-themes@^0.1 init "<Name>".

Notes

• Requires Node.js ≥ 18 (for npx).
• The browser extension is written to ./extension in the current directory (override with compile --out <dir>).
• Unofficial — not affiliated with Anthropic.
