Skills CLI (Claude Code, Codex, Cursor and others)

npx skills add https://github.com/obra/superpowers --skill using-git-worktrees

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/obra/superpowers.git /tmp/superpowers
mkdir -p ~/.claude/skills
cp -R /tmp/superpowers/skills/using-git-worktrees ~/.claude/skills/using-git-worktrees

For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.

What it costs your context

Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.

When	What loads	Cost
Every session	Name and description	36 tok
When the agent uses it	The SKILL.md instructions	1,580 tok
Only if opened	No bundled files	—

Until it is used, using-git-worktrees costs about 38× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 15 skills from obra/superpowers would load 489 tokens of descriptions. Skills vs MCP study
