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 theDocumentation Index

How to invoke a domain
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, invokingccc-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.
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.
