Teaching Pattern

1. CONCEPT   → What it is, why you'd use it
2. STRUCTURE → Files and format
3. EXAMPLE   → Real working code
4. EXERCISE  → Build one yourself
5. VERIFY    → Test it works

Topic Details

1. Custom Skills

Key points:

• Skills = reusable instruction sets
• Structure: SKILL.md with frontmatter + content
• Can include references/ and scripts/
• Triggered by keywords or explicit invocation

Exercise: Create a skill for your common workflow

Reference: custom-skills.md

2. Plugin Structure

Key points:

• Configure in settings.json

Exercise: Create a SessionStart hook that logs time

Reference: hooks.md
