Nice. Does T3 Code have its own system prompts? Curious if it influences the output/quality of Claude code or codex. My experience with these desktop apps (like Conductor) is that they're not a 1:1 with how the native harnesses behave.

It does inject a prompt and it's own MCP server, so Claude and Codex can both use the in-built browser, in-built phone emulators, in-built Git helpers (PR linking/watching/etc) and a lot more. I can vouch for the quality, been using for quite a while now, would never go back to…
