Changes things 3Claude Code: ask
  • cheapest_monthsThe departure months ranked by observed median price for a route, with the median of each.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    The departure months ranked by observed median price for a route, with the median of each. Answers "when is it cheapest to go" with measured data instead of seasonal folklore.
  • flight_price_verdictAnswers "buy now or wait?" for a route, from 90 days of observed prices: verdict, percentile of today's cheapest fare against its own history, median, all-time low, and sample size…No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Answers "buy now or wait?" for a route, from 90 days of observed prices: verdict, percentile of today's cheapest fare against its own history, median, all-time low, and sample size. This is not a flight search: it judges a price. No other public source computes it, because it needs the price history, not today's snapshot.
  • when_to_bookHow many days before departure this route has historically been cheapest, from our own observations.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    How many days before departure this route has historically been cheapest, from our own observations. Answers "am I booking too early or too late?".
Only reads 1Claude Code: allow
  • watched_routesLists the routes Piratefly observes daily and can therefore judge.No findings

    Why it is in this group

    • The description's first verb is "list": a word for reading.
    Description, as the server wrote it
    Lists the routes Piratefly observes daily and can therefore judge. Call this first, or after any answer saying a route is not watched, to find out what can be asked. Filter by origin and/or destination city (partial city name is fine) or omit both for the full list.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
