The built-in skill-creator turns a plain-English description into a working skill. If you can explain a process to a coworker, you can build one. Here's the whole flow.
The skill-creator is a skill that builds other skills. Turn it on once and leave it on — it's the fastest path from idea to working skill.
Preferences -> Skills -> skill-creator -> toggle ON
Tell Claude what you want the skill to do, the same way you'd brief a new hire on their first day. Name the steps, the inputs it needs, and what a finished result looks like.
Claude writes the underlying SKILL.md for you. You never touch syntax. The clearer your description, the better the skill — so spell out the preferences you'd normally keep in your head.
Run the new skill on a real task right away. If something's off, just say so — "make the summary shorter," "always ask which week first" — and Claude rewrites the skill.
Two or three rounds of this and you'll have something reliable. You're editing by conversation, not by code.
The skill is saved automatically. From now on you trigger it by name and it runs the same way every time. Because a skill is just a folder, sharing it is as simple as sharing files — one person builds it, the whole team runs it.
A clean, commented fill-in-the-blank file. Use it to brief skill-creator, or drop it straight into your skills/ folder.
