I'm building TTT -- a terminal text editor and IDE written in Go. Single binary, zero config, runs anywhere. Think VS Code but in your terminal. It has syntax highlighting, LSP integration, a plugin system, an integrated terminal, git integration, etc...
The source is on GitHub and I develop it with Claude Code as my pair programmer. This is the story of how a frustrating limitation turned into something genuinely useful: a built-in scripted interaction system that lets AI agents (or anyone) drive the editor like Playwright drives a browser.
The problem
I was deep in revamping the widget system and building out a Lua plugin API. Phases of work stacking up -- widget rendering, panel support, tree views, input fields, command registration, keybinding hooks. The kind of work where you need to see what's happening. Click a tree node, check if it expands. Open a panel, verify focus moves correctly. Run a plugin, confirm the dialog appears.
Here's the thing: Claude Code can run shell commands and read files. It cannot interact with a live TUI session. The editor launches, takes over the terminal, and that's it -- Claude is blind.
