Creating Agent Skills
Skills extend agent capabilities with domain-specific knowledge. Use skills for procedural knowledge the agent lacks—not for concepts it already understands.
If guidance is project-specific or one-off, use INSTRUCTIONS.md or inline context instead.
Structure
Required Frontmatter
Every SKILL.md must start with YAML frontmatter on line 1:
---
name: my-skill-name
description: What this skill does and when to use it. Third-person.
