Use Cases

Real-world ways to use Anthropic Skills (Official)

Learn the SKILL.md format by reading the canonical examples

👤 Devs about to write their first skill ⏱ ~30 min beginner

Flow

Pick a reference skill

Use anthropics/skills. Show me the document-handling skill in full. Walk me through its structure.✓ Copied

→ Domain-mapped skeleton

Outcome: Your first skill, structured the way Anthropic recommends.

Pitfalls

Vague description = false triggers — Make description specific to triggering signals; less is more
