A parks planning agent must check weather and the facilities calendar before advising on outdoor event feasibility. What should its tool design include?

A parks planning agent that must check weather and the facilities calendar before advising outdoor event feasibility should include multi-tool schemas for a weather API and a facilities calendar. Explicit schemas let the model call each dependency correctly and combine both signals before recommending a go/no-go. Outdoor feasibility is conjunctive: a free pavilion still fails in severe weather, and perfect weather does not help if the facility is booked. Single-tool schema for a weather API and a facilities calendar before feasibility answers collapses two distinct dependencies into one interface, so the model cannot call weather and calendar with correct separate parameters and combine both signals. Multi-tool schemas for a weather API and a ticketing API before feasibility answers swap the required calendar for ticketing, so ticket sales data cannot confirm whether the pavilion or field is actually free. Multi-tool schemas for a weather API and a facilities archive before feasibility answers swap the live calendar for a historical archive, so past records cannot confirm current availability or that the venue is free now. On the exam, multi-tool schemas for weather and calendar precede feasibility answers; distractors use a single-tool schema, swap the calendar for ticketing, or swap the live calendar for an archive. Caveat: define precedence rules when tools disagree or one fails (e.g., cannot confirm feasibility if weather tool errors)—do not silently assume clear skies. Operational check: register both tool schemas, ask an outdoor-event feasibility question, verify weather and calendar tools are both called, and confirm the advice reflects both results rather than invention.
