How to install
Skill (folder)A Skill is a folder with a SKILL.md file that gives Claude extra instructions for a task.
Claude Code (project or global):
# per-project mkdir -p .claude/skills/bench # ...or for all projects mkdir -p ~/.claude/skills/bench # copy SKILL.md and any supporting files into that folder
Claude.ai / Claude Desktop:
Customize → Skills → “+” → Browse skills → Install. (Installed skills are view-only; download a copy to customise.)
Claude auto-detects skills in that folder — no restart needed.
Exact steps can vary per project — always double-check the original source. New to this? Read the full install guide →
