Claude Skill Editor

A minimalist desktop application for creating, editing, and installing Claude skills with one-click drag-and-drop installation.

Claude Desktop/Web offers access to powerful Claude Skills: modular prompts & scripts loaded for specific tasks.

Unfortunately, Claude Desktop does not offer native editing for skills. You'd have to store them in a separate folder, edit with a text editor, and create a new ZIP archive & upload every time you want to make an edit. I got tired of how long it took to tweak a skill, so I made something to speed it up.

Introducing Claude Skill Editor. Create, edit, and upload skills with only a few clicks (no saving external ZIP archives or managing version separately) but with a full built-in text editor for detailed skill editing.
