What to wear is three agents. A weather agent turns the forecast into typed constraints with rules, and asks Claude only when the day is ambiguous. A stylist (Claude) picks outfits from the closet. Code then checks every pick: ids must be real, an outfit needs one top and one bottom or one dress, and a wet day needs a waterproof layer. Dropped picks are kept as warnings.

What to buy uses no model. Every pair of items is scored by rules, every valid outfit is enumerated, and each candidate is ranked by the new looks it adds, not by raw combinations. A second pair of the same jeans makes 36 combinations and zero new looks.
