There's now more AI harnesses than I can keep up with but so far, I've consistently stuck with Claude Code. At least for serious dev work. What is everyone else using? For work or personal projects?

T3 Code. Works with Claude and Codex CLI under the hood, so technically it's not a harness, more like a GUI for your agents.
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 anything else. Just like /dev/null, it's been built by devs for devs.
