How can an Embabel agent collect missing info from user in chat before executing an action?

Hi! I'm giving Embabel a test drive by re-implementing an agent I previously built with LangChain.
This agent provisions virtual machines in the cloud – it asks the user clarifying questions to determine the desired VM configuration (CPU, RAM, region, etc.), calculates the price, asks for confirmation, and then creates the VM using tools. It also uses tools to fetch available configuration options.

My question is: how can I make an Embabel agent that collects missing parameters for an action by asking the user in chat?

For example, in the Horoscope demo from the docs – how could the agent ask the user for their name and star sign if they weren't provided in the initial message?

See the StarNewsFinder in embabel-agent-examples. It uses WaitFor for this.
