Slupe lets you use web-based LLMs to modify local files without leaving the browser.

npx slupe --clipboard

It's a CLI tool that watches for LLM commands and executes them on your computer. Key features:

- Custom syntax (NESL) designed for LLM reliability - fewer search/replace failures than existing approaches - Clipboard mode: copy from browser → Slupe executes → paste results back to clipboard - Generates instructions for LLMs based on your allowed actions - Sandboxed filesystem operations with configurable permissions + automatic git backups

Motivation: I wanted to use web based Opus 4 and Gemini 2.5 Pro for coding.

Early beta (macOS only, Linux/Windows untested). Would love feedback on UX and security model.
