# CCC Domains: One Skill That Loads an Entire Specialty

> CC Commander's 11 domain routers dispatch to specialist sub-skills on demand. One invoke gives you full coverage for code, DevOps, SaaS, design, or mobile.

A CCC domain is a router skill. When you invoke a domain, it does not give Claude Code a single set of instructions — it dispatches to the right specialist sub-skill based on what your task actually needs. Think of a domain as an expert team lead who reads the brief and assigns the right specialist, rather than trying to do everything themselves.

Each domain comes pre-loaded in the `essential` tier, so you have access to all 11 out of the box without installing anything extra.

## How to invoke a domain

<Tabs>
  <Tab title="From the CCC menu">
    ```bash theme={null}
    ccc
    ```

    Select **Browse domains** from the main menu, then pick the domain that matches your task. The domain router reads your task description and dispatches to the right sub-skill automatically.
  </Tab>

  <Tab title="From inside Claude Code">
    ```
    /ccc:domains
    ```

    Opens the domain browser inline. You can also invoke a specific domain directly:

    ```
    /ccc domains
    ```
  </Tab>

  <Tab title="Direct skill name">
    Each domain is a skill you can load by name. If the Intelligence Layer has not already selected it, reference it directly when starting a dispatch:

    ```
    ccc-saas
    ccc-devops
    ccc-testing
    ```
  </Tab>
</Tabs>

## How routing works inside a domain

When you invoke a domain, the router skill reads your task and selects the specialist sub-skill that best matches. You do not need to know which sub-skill to ask for — the router infers it from your description.

For example, invoking `ccc-saas` with a task like "add Stripe billing with usage-based pricing" routes to the billing sub-skill rather than the auth or multi-tenancy sub-skill. The router uses keyword matching against the sub-skill directory structure to make this decision.

<Note>
  Individual skills inside CCC domains are still accessible directly by their original names via symlinks. If you know the exact sub-skill you need, you can load it without going through the router.
</Note>

## The Intelligence Layer and domains

The Intelligence Layer's skill recommender is domain-aware. If your task description triggers domain-level keyword signals (such as "authentication", "billing", or "deploy"), the relevant domain router ranks highly in the skill recommendation output. You will often see a domain recommended before you even open the domain browser.

<Tip>
  Domains are included in the `essential` install tier. You get all 11 routers by default without any additional install steps.
