Install the Build Test skill
Skills CLI (Claude Code, Codex, Cursor and others)
npx skills add https://github.com/nexu-io/open-design --skill build-test
Claude Code, by hand (all projects)
git clone --depth 1 https://github.com/nexu-io/open-design.git /tmp/open-design mkdir -p ~/.claude/skills cp -R /tmp/open-design/plugins/_official/atoms/build-test ~/.claude/skills/build-test
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 | 31 tok |
| When the agent uses it | The SKILL.md instructions | 607 tok |
| Only if opened | 1 bundled files (1 KB) | varies |
Until it is used, build-test costs about 44× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 150 skills from nexu-io/open-design would load 9,514 tokens of descriptions. Skills vs MCP study
