2. Create SKILL.md with YAML frontmatter:

   ---
   name: skill-name
   description: Trigger phrases and when to use. Max 1024 chars.
   ---
   

3. Add references in skills/wp-your-skill/references/ if needed
4. Update marketplace.json to include the new skill
5. Update README.md skill table

Adding Slash Commands

Create a markdown file in commands/ with:

---
description: What the command does

Code Standards

PHP examples must follow WordPress PHP Coding Standards:

• Spaces inside parentheses: function_name( $arg )
• Use array() not []
• Yoda conditions: if ( true === $value )
• Snake_case for variables/functions
• Prefix custom functions: prefix_function_name()

Use consistent severity labels in skill content:

• CRITICAL: Will cause failures at scale (OOM, 500 errors)
• WARNING: Degrades performance under load
• INFO: Optimization opportunity
