Install the Dev skill

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

npx skills add https://github.com/microsoft/playwright-cli --skill dev

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/microsoft/playwright-cli.git /tmp/playwright-cli
mkdir -p ~/.claude/skills
cp -R /tmp/playwright-cli/.claude/skills/dev ~/.claude/skills/dev

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	27 tok
When the agent uses it	The SKILL.md instructions	30 tok
Only if opened	2 bundled files (8 KB)	varies

Until it is used, dev costs about 50× less than the median MCP server we measured (1,362 tokens on every turn). Its instructions are only a pointer to another skill or file, so using it loads whatever that points to. Installing all 2 skills from microsoft/playwright-cli would load 46 tokens of descriptions. Skills vs MCP study
