What it was

A native, GPU-rendered tiling manager for AI coding agents. Rust + GPUI. Run Claude Code, Codex, Cursor, Gemini, and OpenCode side by side with automatic sub-agent delegation, remote machine targeting via SSH, and persistent sessions.

Why it's archived

After a week of building this, I arrived at a simpler conclusion: **you don't need a custom GUI to orchestrate AI agents.**

Here's what I learned:

**The terminal already won.** Every AI coding CLI (Claude Code, Codex, Cursor Agent, Gemini CLI, OpenCode) ships with a polished terminal TUI. Building a Rust GUI that parses their JSON output and re-renders it will always be worse than just... using the native TUI. Users are comfortable in their terminal. They don't want a new window.

**Delegation is a prompt, not a product.** The entire coordinator/worker delegation system -- spawning sub-agents across runtimes, collecting results, feeding them back -- can be done with 4 lines in a `CLAUDE.md` file telling the model to use `cursor agent --print` or `codex exec` via Bash. No orchestration daemon needed. No hooks. No middleware. Claude Code's Agent tool already handles internal delegation. For external CLIs, just run them headless.

**Token tracking already exists.** [CodexBar](https://github.com/steipete/CodexBar) sits in your macOS menu bar and tracks usage across Claude, Codex, Cursor, Gemini, and more by reading their local data files. No need to build this into a GUI.

**The architectural mismatch.** Using Claude Code (a Node/Bun process) to build and iterate on a Rust GPU application through JSON stream parsing is a bizarre feedback l
