She Built 63 Design Skills for Claude Code. Not an Engineer.
A designer just proved content designers can build their own AI tools. Plus: a sci-fi author ships an app with zero code, your CLAUDE.md is the new style guide, and 4 tools worth knowing.

The Signal
Marie Claire Dean just published 63 skills and 27 commands for Claude Code. Not an engineer. A designer.
Type /discover and Claude runs a full research discovery cycle. Type /strategize and it builds a UX strategy from vision through metrics. Type /handoff and it generates a developer handoff package. Free. Open source.
Here's what nobody's saying: she didn't ask permission. She didn't file a ticket. She didn't wait for the design tools team to "add AI features." She just built the thing her team needed.
The question isn't whether content designers CAN build tools. The question is whether YOU will.

Build of the Week
Eliot Peper can't code. Zero. He used Claude Cowork to build an app, shipped it to the App Store, and now has over 100 users.
Simon Willison said it best: "It was always a surprise when it worked the first time. And now it's expected."
The skill now is describing, not coding.

The Pattern: Your CLAUDE.md Is Your New Style Guide
That 47-page style guide nobody reads? Here's how to make it enforce itself. Tonight.
Claude Code reads a file called CLAUDE.md before every response. Put your voice rules in it — and it follows them.
Try this:
- Pick your top 5 voice & tone rules
- Create
CLAUDE.mdin your project folder - Paste those rules in
- Ask Claude to write something
That's it. Self-enforcing style guide. No training. No meetings.
