Added October 15, 2026. Written with AI assistance and checked for clarity and placeholders; not reviewed by a lawyer, accountant, clinician or other professional. How these prompts are made
The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
[VERIFY] is an editorial flag, not a blank to fill. Wherever the prompt shows [VERIFY], check that item against a reliable source before you use it (what [VERIFY] means).
Design an agent to plan a trip for [TRAVELLERS] to [DESTINATION] between [DATES]. Budget cap and priorities: [BUDGET_AND_PRIORITIES]. Constraints (mobility, diet, children, visa questions): [CONSTRAINTS]. Tools it can use: [TOOLS]. Define the stages: clarify, shortlist options, check opening hours and travel times with sources, draft the itinerary, price it, stress-test it, present choices. For each stage write the agent's instruction, the output format, and the pass condition before moving on. Add guardrails: never book or pay; present at most three options per decision; show a running budget table with the arithmetic; mark every price, schedule or entry rule with its source and date or as [VERIFY]; and stop to ask when two constraints conflict. Provide the stress-test checklist (connection times, rest days, closed days, weather alternatives, a plan if a flight is cancelled) and the final summary format with a page for each day and a packing and documents list. Include one worked example for a three-day city break with an invented budget so I can see the table.
