@type capability_type() :: :tool | :resource | :prompt
```

# `child_spec`

# `list`

```elixir
@spec list(GenServer.server(), capability_type()) :: [capability()]
```

# `list_all`

```elixir
@spec list_all(GenServer.server()) :: [capability()]
```

Lists all capabilities.

# `lookup`

```elixir
@spec lookup(GenServer.server(), capability_type(), String.t()) ::
  {:ok, capability()} | {:error, :not_found}
```

Looks up a capability by type and name.

# `register`

```elixir
@spec register(GenServer.server(), capability_type(), String.t(), module(), map()) ::
  :ok
```

Registers a capability.

# `start_link`

```elixir
@spec start_link(keyword()) :: GenServer.on_start()
