Refining a prompt involves adding constraints that narrow the range of possibilities to better fit the user's practical reality. Indicating thesize of the partyis a high-value refinement because it fundamentally changes the nature of the suggestions the AI will generate. Planning a party for five children at home is a radically different logistics task than planning a party for 50 people at a rented venue.

By adding the party size, the AI can filter out suggestions that are physically or financially impractical. For example, if the size is "small/intimate," the AI might suggest DIY crafts or board games. If the size is "large/corporate," it might suggest catering options and venue rentals. While knowing "why" the party is thrown (Option A) provides some context, the "how many" (Option B) is a concrete constraint that dictates the feasibility of all subsequent ideas. Providing a child's full name (Option D) is a privacy risk and provides zero functional value to the AI's creative process. Effective refinement focusing on scale and constraints ensures that the AI’s output is actionable rather than just imaginative.
