🟢plan_reception_layout(guest_count, room_length_ft, room_width_ft, table_shape, seats_per_table, ...)

Use this when someone wants to plan a wedding reception floor plan, figure out how many tables fit in a room, or check whether a venue space can hold their guest count with a dance floor, bar, buffet, DJ or band, and head table. Needs guest count; room dimensions in feet are optional (if missing, returns the space required instead of a fit check). Do not use for ceremony seating, seating assignments by name (use generate_seating_chart), or venue search.

🟢generate_seating_chart(guests, seats_per_table, table_count, keep_together, keep_apart, ...)

Use this when someone has a list of wedding guests and wants them assigned to tables, keeping families, friend groups, or couples together and keeping specific people apart. Accepts names with optional group labels and keep-apart pairs. Returns table assignments and a shareable chart. Do not use for floor plans without names (use plan_reception_layout) or for RSVP tracking.

⚪estimate_wedding_budget(total_budget_usd, guest_count, region, priorities, style)

Use this when someone gives a total wedding budget, a guest count, or both and wants a category-by-category split (venue, catering, photo and video, flowers, music, attire, stationery, and so on) with per-guest math and a contingency line. Do not use for tracking actual spending or vendor payments.
