Vesper
“evening”
warmfadingwide
The last light of evening over a wide plain, with a sun half set at the edge.
If you like Rosé Pine, you will feel at home here.
A plum evening sky over a plain of thin lines, with a sun half set in one corner. Held still, as it is while you read.
The plate
A wide plain at the end of the day. By day it is an early dusk in peach and rose. By night the sky turns plum, a magenta and amber afterglow lies low in the corners, and a sun sits half below the horizon. While Claude works, the lines of the plain glide slowly toward you and bands drift down the sun. When the answer is ready, the evening holds still.
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.
- Settling
- Fading to dusk
- Following the horizon
- Watching the afterglow
- Waiting for the first star
After a turn of 20 seconds or more, Vesper 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.

/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 Vesper
Each plate also installs by its own name, and its commands use that name, such as /vesper still or /vesper music.
/plugin install vesper --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.
