### Tool changes

- 2026-10-30 `plan_night_out` changed (description, inputSchema)
  - before: Plan dinner, drinks and a live music venue in one city for 2 to 6 friends. Give the city and each friend's name with 1 to 4 music artists, movies, TV shows or books they love. Qloo's cross-domain taste graph turns that shared taste into real venues. Each stop is the venue whose least happy friend is happiest, and Qloo explainability names the favourites behind it, with the share of each friend's taste.
  - after: Plan dinner, drinks and a live music venue in one city for 2 to 6 friends. Give the city and each friend's name with 1 to 4 music artists, movies, TV shows or books they love. Optionally give an exact night date as YYYY-MM-DD; Qloo then filters venues by that date's weekday only, not by exact opening times, travel or availability. Qloo's cross-domain taste graph turns that shared taste into real venues. Each stop is the venue whose least happy friend is happiest, and Qloo explainability names the favourites behind it, with the share of each friend's taste.

## Tools (2)

- `find_common_ground`: Pick ONE movie, TV show, book, music artist, podcast, restaurant (kind=place, with location) or destination that a whole group will enjoy. Give each person's name and 2 to 5 things they love. Favourites can come from another category with tasteFrom, for example music artists to pick a restaurant, or any for a mix of artists, movies, TV shows and books. Uses Qloo's taste graph to score every candidate for every person and returns the option that makes the least happy person as happy as possible, with a reason per person.
