Running into an issue when creating a new action *outside* of the agentkit repo

[floAr]

🐛 Describe the bug

We are trying to create a new action for agentkit. For the sake of time we were trying to create it in our agent project, which has agentkit as a dependency.
For some reason the CreateAction decorator is really unhappy outside of the agentkit project itself.
Example is here: https://github.com/floAr/ReadyAgentOne/blob/main/agent/superfluid/superfluidStreamActionProvider.ts

I tried and reproduced with the minimal example here https://github.com/coinbase/agentkit/tree/master/typescript/agentkit#creating-an-action-provider

It fails to compile with:

Unable to resolve signature of method decorator when called as an expression.
 The runtime will invoke the decorator with 2 arguments, but the decorator expects 3.ts(1241)
actionDecorator.d.ts(69, 114): An argument for 'descriptor' was not provided.
Decorator function return type 'object' is not assignable to type 'void | ((args: { myField: string; }) => Promise<string>)'.ts(1270)

Added a minimal not working sample here: https://github.com/floAr/issue-repro

Versions

"node_modules/@coinbase/agentkit": "version": "0.1.1",

The @coinbase/agentkit package makes use of decorators to support defining actions seamlessly within the ActionProvider implementation.

You need to add the following compilation options to your tsconfig.json and it will resolve the compiler issues.

{
 "compilerOptions": {
 "experimentalDecorators": true,
 "emitDecoratorMetadata": true
 }
}
