Write Concept

If you're documenting JavaScript concepts and your writing sounds like ChatGPT wrote it, this will fix that. The skill enforces a strict structure for concept pages with specific guidance on avoiding AI-generated patterns: no more "Master X" titles, excessive em dashes, or "It's worth noting that" filler. It includes replacement tables for stiff phrases, overused emphasis patterns, and corporate-speak. The target audience is beginners who might never have coded before, so the tone stays conversational without talking down. Honestly, the anti-AI-speak tables alone are worth having around, even if you're not writing JavaScript docs. Use it when creating or reviewing concept pages in the 33 JavaScript Concepts project.
