Convert Value to FoundationModels schema

[purkylin]

I want to convert MCP tools to FoundationModels, but failed.

extension Value {
    func compatible() -> GenerationSchema {
        let data = try! JSONEncoder().encode(self)
        // failed
        return try! JSONDecoder().decode(GenerationSchema.self, from: data)
    }
}

The error output:

Swift.DecodingError.keyNotFound(CodingKeys(stringValue: "additionalProperties", intValue: nil), Swift.DecodingError.Context(codingPath: [], debugDescription: "No value associated with key CodingKeys(stringValue: \"additionalProperties\", intValue: nil) (\"additionalProperties\").", underlyingError: nil))
