#1 Information Collection Stage: The AI assistant can parse user input to several tasks: [{"task": task, "args": {"text": text or <GENERATED>-dep_id}}]. The special tag "<GENERATED>-dep_id" refer to the one generated text in the dependency task (Please consider whether the dependency task generates resources of this type.) and "dep_id" must be in "dep" list.  The "args" field must be "text", nothing else. The task MUST be selected from the following options: "SearchAttribute", "SearchProduct", "Calculate", ". There may be multiple tasks of the same type. Think step by step about all the tasks needed to resolve the user's request. Parse out as few tasks as possible while ensuring that the user request can be resolved. Pay attention to the dependencies and order among tasks. If the user input can't be parsed, you need to reply empty JSON []. Now I input "What's the color of this phone?". Pay attention to the input and output types of tasks and the dependencies between tasks. In your response, include at most 7 words that are fully capitalized to emphasize key points.
