Trinidad Head

Trinidad Head is a terminal app for Windows and macOS, written from scratch in Rust. Every window is dark glass with a glowing neon rim, every open window picks a different color, and your own prompts in a Claude Code chat sit in their own bubble so they are easy to find when you scroll back.

A Trinidad Head window: dark glass with a glowing orange rim

Who it is for

  • People who keep several terminals open at once and lose track of which is which. Each window takes one of eight glow colors that no other open window is using.
  • People who spend long sessions in Claude Code or other AI command line tools. Trinidad Head is not an AI tool itself; it is the window those tools run in, with a few features aimed at them (see below).
  • People running local models from the command line, who want each model's window to look different from the others.

What it does

  • A color per window. Eight glow themes: aurora, ember, tide, rose, ocean, gold, violet and lime. A new window takes the first one no other open window uses. The palette button on the side of the window cycles that window's color.
  • Your prompts stand out. Cells painted in Claude Code's "your message" bar color are drawn as a see-through pill with bigger, bold, green text.
  • Faint text looks faint. Text marked faint (SGR 2), such as Claude Code's ghost suggestion, is drawn at a third of its brightness.
  • Select and copy, even inside full-screen programs. Drag to select, even when the program has taken the mouse (Claude Code's full-screen view, for example). A plain click still goes to the program; a drag becomes a selection. Keep dragging past the top or bottom edge and the view keeps scrolling.
  • Edit Claude Code's prompt like a text box. Highlight words inside Claude Code's input box and press Backspace or Delete to remove them, or type or paste over them.
  • Nothing copies by itself. Selecting does not copy. Copy with Cmd+C (Mac), Ctrl+C with a selection (Windows), or the right-click menu.
  • Links and files. Cmd+click (Mac) or Ctrl+click (Windows) opens a web link. Dropping files on the window types their paths, which Claude Code turns into attachments.
  • Dictation and input methods go through the Mac's own text input system.
  • A typing-delay meter on Windows shows the median and 95th percentile time from key press to the frame that shows the echo, in the window title.
  • One Dock icon on the Mac, however many windows are open.

Made for local models too

If you run models on your own computer, Trinidad Head pairs with Claude Code Local, a separate project by the same author. The screenshot below is from the v0.1.0 release. The "keep going" command and the model menu in it come from that project, not from Trinidad Head; Trinidad Head is the window drawing it.

What it is not (yet)

These limits come straight from the README and the code:

  • No Linux window. On Linux the program prints trinidad-head: there is no window for this OS yet and exits.
  • One shell per window. No tabs or splits.
  • No settings screen. The one setting (the default glow) lives in a small text file. See Configuration.
  • The Windows download is not code-signed, so SmartScreen warns on first launch. The Mac download is signed with a Developer ID and notarized.
