How to Draft a Travel Itinerary from Constraints Only
Itineraries invent flights. Sequence only the dates and places in Limits. BOOKING NOT IN INPUTS.
The matching generator is the Travel Itinerary from Constraints Only (No Invented Bookings) prompt. Browse related cards in the PromptDig library (Browse more prompts). When a filled run survives, share the version you actually use (Share a prompt).
Build the calendar from pasted dates only
Draft a travel itinerary from pasted constraints only. Never invent bookings, prices, or confirmation numbers. Start by filling Inputs, not by asking the model to remember last week's run. If a field is blank, write NONE or NOT IN INPUTS and leave it blank through Generate. The card is built so the model cannot honestly invent a number, owner, URL, or command that you did not paste.
Paste these fields before you hit run:
Constraints (dates, places, musts, hard nos): [Limits]
Home I may name (or UNKNOWN): [Home]
Transport I already booked (or NONE): [Booked]
Words I must not use: [Banned]
What I must never invent: [Never]
Output format: [Format]
Language: [Lang]
Budget I may state (or UNKNOWN): [Budget]
That inventory is the honesty ledger. Anything that does not appear there is forbidden in the draft. If you catch yourself adding a nice-to-have after the run, you are no longer using the card. You are ghostwriting. Put the extra fact in Inputs and run again.
Cities only as named in constraints
Generate is numbered on purpose. Do not skip a step because the first paragraph looked done. The early steps exist to stop later prose from smuggling claims.
Walk the Generate list in order:
- Honesty ledger: Limits nouns, Home, Booked, Budget, Lang. Forbidden: invented flights, invented hotels, invented $.
- Calendar skeleton from dates in Limits only. If dates missing, DATES UNKNOWN and do not pick a month.
- Per-day outline: places from Limits. Activities only if named. Else ACTIVITY NOT IN INPUTS.
- Bookings column: only Booked. All other cells BOOKING NOT IN INPUTS.
- Budget: quote Budget or BUDGET UNKNOWN. Do not split into per-day dollars.
- Refuse: inventing confirmation numbers, inventing restaurant reservations, inventing visa outcomes.
- Never: do not add a city that is not in Limits.
- Compliance pass: Banned and Never. Format as Format.
If a step asks for a version lock, quote the version from Inputs in the output. If a step asks for a refuse list, keep the refuse list in the published artifact, not in a sidebar you delete. Reviewers should see what the model was not allowed to do.
Bookings column only for already-booked items
Most failures are the same shape: a missing field gets a confident fill. A conversion rate appears. A Gradle task appears. A flash point appears. A caption appears on a job that asked for slide text only. Your review is to search the draft for numbers, names, and commands, then grep Inputs. No match means cut.
Honor the constraints as hard stops, not vibes:
- Itinerary from Limits only. Not a booking agent and not a 5-day budget product.
- Never invent bookings, prices, or confirmation numbers.
- No emojis.
When the card says not legal advice, not certification, not an exam dump, or not a caption engine, that sentence belongs at the top of the output. Deleting it to look more finished is how you inherit risk.
Refuse invented confirmation numbers and prices
Finish with the compliance pass the prompt already asks for. Quote the banned-word hits. Cut them. Print character counts when the job has a cap. Print word counts when the job has a budget. List gaps as gaps. Five missing facts are more useful than one smooth paragraph.
Tags on the card (travel itinerary from constraints, no invented bookings, constraints only itinerary) are a reminder of the job shape, not an invitation to wander into a neighboring cluster. If you need a different surface, open a different PromptDig card rather than stretching this one.
Fill the card, then run
Replace every bracket. Run on ChatGPT, Claude, or Gemini. Read the ledger first, then the artifact. If the model invents a commit, KPI, DOI, PEL, bid, or logo, discard the run. Tighten Inputs. Run again. Share the filled card that survived, not the first draft that sounded done.
