Tessera

Terra

“earth”

warmretrogrounded

Flat bands of brick, mustard, moss, teal and plum sweep out of two corners of a warm page.

If you like Gruvbox, you will feel at home here.

Flat concentric bands in earthy colors sweeping out of two opposite corners of a warm page. Held still, as it is while you read.

The plate

A 1970s print poster on a warm page. By night the page is a brown charcoal and the bands are earthy inks; by day it is a cream paperback and the same inks sit on it like a record sleeve. A sun sits in the top left and bottom right corners, ringed by flat bands with rounded ends, and a light speckle runs over the paper. While Claude works the bands sway a few degrees around their corner, and they hold still when the answer is ready.

While Claude works

The spinner takes one of these words in place of “Working”. When the app names the step it is on, that name stays.

  • Taking it easy
  • Kicking back
  • Easy does it
  • Letting it ride
  • Spinning a record
  • Mellowing out

After a turn of 20 seconds or more, Terra plays a soft chime under a second and a half long.

With /tessera music, a quiet loop of its own plays while Claude works and stops when the answer is ready. It is off until you ask for it.

Install

Hang Terra

  1. 1 In the desktop app

    Click + next to the prompt box and choose Plugins. Add the marketplace btahir/tessera, then add the tessera plugin.

    btahir/tessera

  2. 2 In a terminal session

    Paste this at the prompt.

    /plugin install tessera --marketplace btahir/tessera

  3. 3 Ask Claude

    Send this sentence in any session.

    Install the tessera plugin from the btahir/tessera marketplace on GitHub.

Then

The tessera plugin holds all twenty-five plates. Type /tessera terra to hang Terra. /tessera still stops the motion. Sound has three levels: /tessera quiet is silence, /tessera sound is a chime after long turns (the default), and /tessera music adds the room's own quiet loop while Claude works. Your choices are kept across sessions.

Only Terra

Each plate also installs by its own name, and its commands use that name, such as /terra still or /terra music.

/plugin install terra --marketplace btahir/tessera

Where it shows

Themes appear in the Claude Code desktop and mobile apps. The terminal keeps its own colors. The chime plays on macOS only.
