How much of Koog works right now in KMP shared code? I just tried to move some Koog code I had in to commonMain in a KMP project here (with Android, iOS, Wasm and JVM targets).....most seemed fine but getting errors resolving ToolSet and McpToolRegistryProvider

That’s expected, indeed.

Annotation-based tools with ToolSet currently work only on the JVM (because of reflection). For the multiplatform you’ll need to use the class-based tool definitions (https://docs.koog.ai/class-based-tools/) which we’re planing to also simplify and improve (so that you won’t have to implement the ToolDescriptor manually — and likely also serializers won’t be needed either. I think @simon.vergauwen already made a proposal PR for that)

McpToolRegistryProvider is also not available because of the current limitations of the kotlin-mcp SDK (in which, we’re also planning to make the client multiplatform soon)
