Install the Domain Driven Design skill
Skills CLI (Claude Code, Codex, Cursor and others)
npx skills add https://github.com/ciembor/agent-rules-books --skill domain-driven-design
Claude Code, by hand (all projects)
git clone --depth 1 https://github.com/ciembor/agent-rules-books.git /tmp/agent-rules-books mkdir -p ~/.claude/skills cp -R /tmp/agent-rules-books/domain-driven-design ~/.claude/skills/domain-driven-design
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 | 29 tok |
| When the agent uses it | The SKILL.md instructions | 97 tok |
| Only if opened | 3 bundled files (49 KB) | varies |
Until it is used, domain-driven-design costs about 47× less than the median MCP server we measured (1,363 tokens on every turn). Installing all 14 skills from ciembor/agent-rules-books would load 438 tokens of descriptions. Skills vs MCP study
