T3 Code lets coding agents draw live visualizations inside the chat thread
Theo's T3 Code now lets agents build dynamic visualizations inside a thread, styled with the user's own theme. The maker's clip drew 969 likes in about an hour.
T3 Code, the open-source app that lets developers run coding agents from one window, says it has shipped in-app visualization. Theo, its developer, said on X the feature "enables agents to build cool dynamic experiences within the thread". His post carries a short video and had 969 likes when read at around 02:00 UTC on 6 October, about an hour after he posted it.

Theo credited a contributor known as davis7 with pushing for the feature and building most of it. He said he "didn't expect to dig it so much". The post gives no list of what kinds of visualization are supported, and the video is the only demonstration of it so far. Nobody outside the team has publicly tested the feature.
In a reply, Theo said the agent is handed CSS style tokens from the theme the user has chosen, so a visualization should always match the app. Whether that holds is untested. In a second post he called theme compatibility "the coolest part". Both statements are the maker's own, and neither says how well the match holds across custom themes.
T3 Code describes itself on GitHub as an agent harness control surface that works with providers including Claude Code and Codex, across desktop, web and phone apps. The repository is MIT-licensed and showed 25.6k stars when read. Its README warns the project is "very very early" and says users should expect bugs, so the feature may be rough.
