# SelfCapabilities

> SelfCapabilities manages the capability state for the self participant.

SelfCapabilities manages the capability state for the self participant.

Capabilities are received from the server via `call.joined` events and determine
what actions the current participant is allowed to perform.

Each capability is exposed as both:

* An observable (e.g., `end$`) for reactive state management
* A synchronous getter (e.g., `end`) for immediate access

Member-level capabilities are accessed via the grouped `self` / `member` accessors:

* `capabilities.self.muteAudio` (sync)
* `capabilities.self$` (observable)

When a new `call.joined` event is received, the capabilities state is
completely replaced (not merged).

> **Info**
>
> Each capability is exposed in **both forms** on every page below — an
> observable (e.g. `end$`) for reactive UI binding, and a synchronous
> getter (e.g. `end`) for one-shot reads. The accessor cards below list
> the observable; click through for both signatures plus an example.
