Struct SessionPluginResponse 

pub struct SessionPluginResponse {
    pub capabilities: Vec<Capability>,
    pub metadata: Option<Value>,
}

What a session lifecycle hook returns: the capability set plus optional metadata the plugin wants persisted onto the session.

Returned by ChatEngineBackendPlugin::on_session_created, on_session_updated, and on_session_type_configured. For the session-bound hooks (on_session_created / on_session_updated) Chat Engine merges metadata into Session.metadata. For on_session_type_configured there is no session, so metadata is ignored.

Fields

capabilities: Vec<Capability>

Capabilities to expose — stored as Session.enabled_capabilities (session hooks) or SessionType.available_capabilities (type hook).

metadata: Option<Value>

Optional metadata merged into the owning session’s metadata (object merge; plugin keys override existing same-name keys). None leaves the session metadata untouched.
