public sealed class ExtensionManifest : IMessage<ExtensionManifest>, IEquatable<ExtensionManifest>, IDeepCloneable<ExtensionManifest>, IBufferMessage, IMessage
Reference documentation and code samples for the Vertex AI v1beta1 API class ExtensionManifest.
Manifest spec of an Extension needed for runtime execution.
Required. The natural language description shown to the LLM.
It should describe the usage of the extension, and is essential for the LLM
to perform reasoning. e.g., if the extension is a data store, you can let
the LLM know what data it contains.
