code-editor-switch

Purpose

Use this skill to switch Finder/Open defaults for code, text, and config files to a new editor (for example Zed, VS Code, Cursor) using duti.

When to use

• Migrating from one editor to another on macOS.
• Standardizing file defaults for local repos and team machines.
• Fixing mismatched defaults for dotfiles and config files.

Non-negotiable rules

• Run this only on macOS.
• Prefer duti over direct LaunchServices plist edits.
• Apply both generic UTIs and concrete extensions/names.
• Keep public.data opt-in only (--apply-public-data).
• Verify with duti -x after applying mappings.
