Test results

Safe mode: only tools labeled read-only were run. How the test works

• !
  Every tool is described

  1 warning

  • !request_booking: Inputs with no description: pickup, dropoff, pax, flight, notes
  note
• !
  Tools work with good inputs

  1 warning

  • !check_availability: Answered, but it gives the exact same answer to bad input as to good input, so it may be ignoring what it is sent
  • –get_service_info: Not run: labeled read-only, but its description says "Transfers", which usually means it changes something. Skipped to be safe: if it only reads, a clearer description helps AI apps too, or test again with --owner
  • –request_booking: Not run: labeled as changing data
  • and 1 more
  note
• !
  Bad inputs give a clean error

  4 warnings

  • !get_quote: Accepted missing required input "pickup" without complaining
  • !get_quote: Accepted wrong type for "pickup" without complaining
