Resolved 💬 6 comments Opened Jul 25, 2025 by bl-ue Closed Feb 28, 2026

tweakcc is a lightweight, interactive CLI tool that lets you personalize your Claude Code interface.

<img src="https://github.com/Piebald-AI/tweakcc/raw/main/assets/demo.gif" alt="Animated GIF demonstrating running npx tweakcc, creating a new theme, changing all of Claude Code's UI colors to purple, changing the thinking format from '<verb>ing...' to 'Claude is <verb>ing', changing the generating spinner style to a 50m glow animation, applying the changes, running Claude, and using '/config' to switch to the new theme, and sending a message to see the new thinking verb format." width="800">

With tweakcc, you can

  • Customize all of Claude Code's system prompts
  • Create custom toolsets that can be used in Claude Code with a new /toolset command
  • Manually name sessions in Claude Code with /title my chat name or /rename
  • Create custom themes with a graphical HSL/RGB color picker
  • Add custom thinking verbs that will show while Claude's working
  • Create custom thinking spinner animations with different speeds and phases
  • Change the "CLAUDE CODE" banner text to your own text with your own figlet fonts
  • Supports Claude Code installed on Windows, macOS, and Linux, using npm, yarn, pnpm, bun, Homebrew, nvm, fnm, n, volta, nvs, and nodenv, or a custom location
  • Style the user messages in the chat history beyond the default plain gray text
  • Remove the ASCII border from the input box

tweakcc also

  • Restores the token counter and elapsed time metric that were shown during generation before Claude Code 1.0.83
  • Fixes a bug where the spinner animation is frozen if you have the CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC environment variable set (#46)
  • Allows you to change the context limit used with models from custom Anthropic-compatible APIs with a new environment variable, CLAUDE_CODE_CONTEXT_LIMIT

Additionally, we're working on features that will allow you to

  • Pick from over 70+ spinning/thinking animations from cli-spinners
  • Apply custom styling to the markdown elements in Claude's responses like code, bold, headers, etc
  • Customize the shimmering effect on the thinking verb: disable it; change its speed, width, and colors

Run without installation:

$ npx tweakcc

# Or use pnpm:
$ pnpm dlx tweakcc
