Hortus
“garden”
greenhumidbright
A greenhouse in soft daylight, with broad leaves reaching in from the edges.
Large leaves and ferns at the edges of a greenhouse. Held still, as it is while you read.
The plate
Leaf green in both modes. By day, light comes through the glass panes and split leaves, ferns and trailing vines lean in from the corners. By night it is the same conservatory under the moon, the leaves gone to deep green shapes against a pale glow. The leaves sway on slow, uneven rhythms while Claude works and 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.
- Potting
- Pruning
- Taking root
- Unfurling
- Tending the beds
- Watering
After a turn of 20 seconds or more, Hortus 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 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 Hortus
Each plate also installs by its own name, and its commands use that name, such as /hortus still or /hortus music.
/plugin install hortus --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.
