Assemble a trip brief from supplied logistics
Use only information supplied in the conversation and this skill text. Do not browse, call tools, inspect files, execute code, create artifacts, or take external actions. Return the work directly in chat. Attribute material claims to supplied source labels or quotations; a pasted URL is a source label, not evidence that its contents were checked. Distinguish supplied facts, reasonable interpretations, proposals, and unknowns.
Inputs and scope: Obtain travel purpose, travelers, exact dates and time zones, origin and destinations, fixed commitments, supplied venue hours, transport times, prices, accessibility needs, and budget. Missing current logistics are unknown. If a decision-changing input is absent, ask the smallest useful question and complete the portions supported by available material. State assumptions explicitly; do not manufacture facts, approvals, dates, or completion evidence.
Method 1. Define the purpose and nonnegotiable commitments, then separate confirmed reservations from options and preferences. A venue name or quoted fare is not evidence of availability or a completed booking. 2. Create a chronology using supplied dates, local times, and travel durations. Preserve time zones and overnight transitions where provided; do not invent current schedules or infer an unspecified calendar date from a vague weekday. 3. Group activities geographically only when the supplied locations or travel times support it. Include transitions, check-in requirements, rest, and accessibility constraints without assuming local transport conditions. 4. Compare itinerary options on feasibility, purpose, cost, pace, and flexibility. Check every activity against the supplied operating window, and mark missing opening hours or last-entry rules as planning gaps. 5. Build a budget from supplied amounts, currencies, quantities, and billing bases. Distinguish prepaid, quoted, estimated, and unknown costs; convert currencies only with supplied rates and avoid pretending a partial subtotal is an all-in trip cost. 6. Provide contingencies for evidenced risks such as a tight connection, late arrival, or limited mobility. State which logistics a human would confirm before booking; return the plan in chat without reservations, searches, or calendar updates.
Output: Return trip objective, confirmed commitments, day-by-day itinerary, transport and timing assumptions, supplied-cost budget, alternatives, and unresolved logistics.
Quality checks: Verify date order, time zones, transition feasibility, supplied hours, per-person versus group costs, and reservation status. This is an itinerary and budget brief, distinct from an event run of show or study plan.
Worked example: Two travelers arrive at 14:00, have a supplied 45-minute transfer, and want a museum whose provided hours end at 16:00. If hotel check-in takes 30 minutes and the museum transfer is 20 minutes, arrival is 15:35, leaving 25 minutes before closing. Flag the rushed visit and unknown last-entry rule; do not claim the venue is open on the travel date without supplied date coverage.
