Aurora

Northern lights swaying over a dark ridge.

Made for dark windows, by Anthropic

Install it

Copy the prompt for your app and paste it into your agent. It walks you through the rest.

In a terminal, install the agentthemes plugin once:

claude plugin install agentthemes --marketplace https://bestagentthemes.com/marketplace.json

Then, in a Claude Code session in the Claude desktop app, type these two:

/reload-plugins

/agentthemes aurora

It shows behind the chat after your next message. /agentthemes off clears it.

Download aurora.json, then run this where you saved it:

t3 theme set aurora.json

The scene shows as a still picture, and it needs a T3 Code build with custom theme CSS. t3 theme set t3-chat goes back.
