Creating Skills

Create portable, reusable expertise that extends Claude's capabilities across contexts.

When to Create Skills

Skills are appropriate when:

• Capability needed across multiple projects/conversations
• Procedural knowledge that applies broadly (not project-specific)
• Instructions should activate automatically on trigger patterns
• Want portable expertise that loads progressively on-demand

Not appropriate when:

• Context is project-specific (use Project instructions instead)
• One-off task (use standalone prompt instead)
• See crafting-instructions skill for detailed decision framework
