Aurora

“dawn”

coldvastluminous

Northern lights over a snowy ridge on a long polar night.

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

Green and violet northern lights over a snowy ridge. Held still, as it is while you read.

The plate

Polar teal in both modes. By night, green and violet curtains of light hang from the upper corners over a dark sky with a few stars, and low ridges of snow with small spruce trees sit in the bottom corners. By day the same lights are faint pastel veils over a pale dawn. While Claude works the curtains drift and slowly brighten and dim, 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.

  • Shimmering
  • Drifting
  • Glowing
  • Waiting for the lights
  • Watching the sky

After a turn of 20 seconds or more, Aurora 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 Aurora

  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 aurora to hang Aurora. /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 Aurora

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

/plugin install aurora --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.
