What extension have you always wanted in your editor?

rhun is a small, open-source code editor. It has extensions now, and I’d love to see what people make with them.

We’ve added Claude Code and Codex skills for building and testing your own extension, plus a skill for porting open-source VS Code extensions. Describe the tool you want, then work on it with your agent. Rust/Go templates, examples and CLI commands give you a place to start and a way to share it.

What’s the oddly specific extension you’ve always wanted?
