Skill Structure (For the Curious)

A skill is essentially one SKILL.md file.

my-skill/
β”œβ”€β”€ SKILL.md           # Core (required)
β”œβ”€β”€ reference.md       # Detailed docs (optional)
β”œβ”€β”€ examples.md        # Examples (optional)
└── scripts/           # Scripts (optional)
Enter fullscreen mode Exit fullscreen mode

SKILL.md Example 

---
name: react-best-practices
description: React best practices. Auto-applied when writing components.
---

## Component Rules

1. Use functional components
2. Define props with TypeScript interfaces
3. useReducer over useState (complex state)
4. Always specify useEffect dependencies
5. Memoize only when necessary

## Don'ts

- Class components
- any type
- Inline styles (use Tailwind)
Enter fullscreen mode Exit fullscreen mode

The AI reads this file and follows the rules.

Create Your Own Skill

Using others' skills is great, but you can also create project-specific skills.

Step 1: Create Folder 

mkdir -p .claude/skills/my-rules
Enter fullscreen mode Exit fullscreen mode

Step 2: Write SKILL.md 

---
name: my-rules
description: Our team's coding rules
---

## Required

1. Variables in camelCase
2. Functions under 20 lines
3. Comments explain "why"
4. Error handling required

## Forbidden

- console.log (production)
- any type
- Magic numbers
Enter fullscreen mode Exit fullscreen mode

Step 3: Done

Now it auto-applies when you code.
