Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/currents-dev/playwright-best-practices-skill.git /tmp/playwright-best-practices-skill
mkdir -p ~/.claude/skills
cp -R /tmp/playwright-best-practices-skill/playwright-best-practices ~/.claude/skills/playwright-best-practices

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	214 tok
When the agent uses it	The SKILL.md instructions	4,680 tok
Only if opened	58 bundled files (719 KB)	varies

Until it is used, playwright-best-practices costs about 6.4× less than the median MCP server we measured (1,362 tokens on every turn). Skills vs MCP study
