What it does
Domain Driven Design is an agent skill from ciembor/agent-rules-books. Apply Eric Evans-inspired DDD rules when modeling a complex domain, defining bounded contexts, protecting ubiquitous language, or designing aggregates.
Its SKILL.md is about 180 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `domain-driven-design.md`, `domain-driven-design.mini.md` and `domain-driven-design.nano.md`).
It sits in Development, covering Domain-driven design. The repository describes itself as: AGENTS.md rules / skills for AI coding agents: Codex, Cursor & Claude Code. Inspired by Clean Code, Refactoring, DDD, Clean Architecture and DDIA programming books. The licence is MIT.
When your agent uses it
- Tasks that involve Domain-driven design
Example prompts
- “/domain-driven-design”
What it can do on your machine
Read from SKILL.md and the folder at commit 893a88a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Domain Driven Design loads about 177 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 55 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Domain-Driven Design Skill
Use this skill when a task involves strategic domain modeling, ubiquitous language, bounded contexts, context mapping, aggregates, repositories, domain services, or model-driven design.
Before making design or code decisions, read and apply domain-driven-design.mini.md. Use domain-driven-design.md only as a deeper reference when the mini rules are not enough for the current domain-modeling tradeoff.

When should I use Domain Driven Design?
Domain Driven Design fits situations like: tasks that involve Domain-driven design.
How do I install Domain Driven Design in Claude Code?
Run `npx skills add ciembor/agent-rules-books --skill domain-driven-design -a claude-code`. Or copy the skill folder (domain-driven-design in ciembor/agent-rules-books) into .claude/skills/domain-driven-design in your project. Claude Code loads it when a task matches its description.
How do I install Domain Driven Design in Codex?
Run `npx skills add ciembor/agent-rules-books --skill domain-driven-design -a codex`. Or copy the skill folder (domain-driven-design in ciembor/agent-rules-books) into .agents/skills/domain-driven-design in your project. Codex loads it when a task matches its description.
Can I use Domain Driven Design in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ciembor/agent-rules-books --skill domain-driven-design -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/domain-driven-design, .gemini/skills/domain-driven-design, .github/skills/domain-driven-design and .opencode/skills/domain-driven-design in your project.
What does Domain Driven Design need to run?
SKILL.md names no scripts, command-line tools or credentials: Domain Driven Design is instructions for the agent only.
Does Domain Driven Design access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Domain Driven Design safe to install?

What licence does Domain Driven Design use?
Domain Driven Design is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Domain Driven Design use?
About 177 tokens (SKILL.md is roughly 708 characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
