Turn expertise into reusable agent instructions

Direct answer

An Agent Skill is a versionable directory that states when to intervene, how to perform a task, and which resources to load. It is useful for repeated procedures that must stay consistent across conversations.

What you will be able to do

• Distinguish a skill from a one-off prompt, a tool, and an agent.
• Structure SKILL.md, scripts, references, and assets without flooding context.
• Test activation, outputs, and edge cases before distribution.
