T3 Code lets your agent restyle the app with theme colors and CSS

T3 Code's nightly build now lets an agent restyle the app for you. Ask it to change how T3 Code looks and the interface updates on the fly. The feature isn't in the stable release yet.

Themes can now carry custom CSS, and two new agent tools do the work. One reads the existing themes along with a styling guide. The other publishes a theme, colors and CSS together, and switches the web and desktop clients of that server to it. The agent has to be running on the server's machine. It can also switch you between light, dark and system mode. If you'd rather write the CSS yourself, the theme editor has a Custom CSS section with a live preview.

Theme CSS can't load remote files. Clients drop @import and any url() that isn't a data address, so an imported theme can't send what's on your screen to another host.

The change is merged into T3 Code's main branch and is currently only in the nightly build. On stable, asking your agent to customize the app won't do anything yet.
