Install the PR Labeling skill

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

npx skills add https://github.com/vercel-labs/skills --skill pr-labeling

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/vercel-labs/skills.git /tmp/skills
mkdir -p ~/.claude/skills
cp -R /tmp/skills/.vc/automations/workflows/pr-labeling/skills/pr-labeling ~/.claude/skills/pr-labeling

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	22 tok
When the agent uses it	The SKILL.md instructions	236 tok
Only if opened	No bundled files	—

Until it is used, pr-labeling costs about 62× less than the median MCP server we measured (1,363 tokens on every turn). Installing all 3 skills from vercel-labs/skills would load 106 tokens of descriptions. Skills vs MCP study
