# Capabilities Catalog (Topology)
|
|
|
|
> **Note:** this page lists **Topology** capabilities — what a *cluster* can
|
|
> do, exposed as trait bounds a `Score` requires. Apps compose Scores; see
|
|
> [Application Scores](../guides/application-capabilities.md).
|
|
|
|
A `Capability` is a specific feature or API that a `Topology` offers. `Interpret` logic uses these capabilities to execute a `Score`.
|
|
|
|
This list is primarily for developers **writing new Topologies or Scores**. As a user, you just need to know that the `Topology` you pick (like `K8sAnywhereTopology`) provides the capabilities your `Scores` need.
