What it does

Domain Driven Design is an agent skill from davila7/claude-code-templates. Plan and route Domain-Driven Design work from strategic modeling to tactical implementation and evented architecture patterns.

Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/ddd-deliverables.md`).

It sits in Development, covering Domain-driven design. The repository describes itself as: CLI tool for configuring and monitoring Claude Code. The licence is MIT.

When your agent uses it

  • Tasks that involve Domain-driven design

Example prompts

  • “/domain-driven-design”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Run a viability check before committing to full DDD.
  2. Produce strategic artifacts first: subdomains, bounded contexts, language glossary.
  3. Route to specialized skills based on current task.
  4. Define success criteria and evidence for each stage.

What it can do on your machine

Read from SKILL.md and the folder at commit 46b4d8b. 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 623 tokens when it runs, and up to ~777 if it reads all its reference files. Until then it costs about 37 tokens; SKILL.md has 255 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~623
With references · SKILL.md plus every file in references/, read only if the agent opens them
~777

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

Use this skill when

  • You need to model a complex business domain with explicit boundaries.
  • You want to decide whether full DDD is worth the added complexity.
  • You need to connect strategic design decisions to implementation patterns.
  • You are planning CQRS, event sourcing, sagas, or projections from domain needs.

Do not use this skill when

  • The problem is simple CRUD with low business complexity.
  • You only need localized bug fixes.
  • There is no access to domain knowledge and no proxy product expert.

Instructions

  1. Run a viability check before committing to full DDD.
  2. Produce strategic artifacts first: subdomains, bounded contexts, language glossary.
  3. Route to specialized skills based on current task.
  4. Define success criteria and evidence for each stage.
Viability check

Use full DDD only when at least two of these are true:

  • Business rules are complex or fast-changing.
  • Multiple teams are causing model collisions.
  • Integration contracts are unstable.
  • Auditability and explicit invariants are critical.
Routing map
  • Strategic model and boundaries: @ddd-strategic-design
  • Cross-context integrations and translation: @ddd-context-mapping
  • Tactical code modeling: @ddd-tactical-patterns
  • Read/write separation: @cqrs-implementation
  • Event history as source of truth: @event-sourcing-architect and @event-store-design
  • Long-running workflows: @saga-orchestration
  • Read models: @projection-patterns
  • Decision log: @architecture-decision-records

If templates are needed, open references/ddd-deliverables.md.

Output requirements

Always return:

  • Scope and assumptions
  • Current stage (strategic, tactical, or evented)
  • Explicit artifacts produced
  • Open risks and next step recommendation

Examples

text
Use @domain-driven-design to assess if this billing platform should adopt full DDD.
Then route to the right next skill and list artifacts we must produce this week.

Limitations

  • This skill does not replace direct workshops with domain experts.
  • It does not provide framework-specific code generation.
  • It should not be used as a justification to over-engineer simple systems.
