Where it runs, and how to install it
Agent Skills are a format, not a product feature: a folder with a SKILL.md and whatever files it needs. Nothing inside one is model-specific.
- Claude
- Drop the skill folder into ~/.claude/skills/, or upload it in Settings → Capabilities. Claude loads it when the description matches what you asked for.
- Claude Code
- Same folder, per-project instead: .claude/skills/ inside the repository, so the skill travels with the work rather than with the machine.
- Any agent that reads SKILL.md
- A skill is a folder with a SKILL.md and whatever files it needs. Nothing in the format is model-specific, so a runtime that reads the file reads the skill.
