Midnight Fireworks

Fireworks open and fade over a city skyline while windows blink and the river catches the colors.

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 midnight-fireworks

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

Download midnight-fireworks.json, then run this where you saved it:

t3 theme set midnight-fireworks.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.
