Questions
Claude Code and skills.
What is a Claude Code skill?
A folder with a SKILL.md file: instructions, and sometimes scripts and reference files, that Claude Code loads when a task calls for them.
How do I install a skill in Claude Code?
Each skill page has an install command. Run it in a terminal, then start a new Claude Code session so the skill is picked up.
What is the difference between a skill and an instructions file such as AGENTS.md?
An instructions file is loaded in every session and describes the project. A skill is loaded only when a task calls for it, so it can be long and specific without costing context on every turn.
