## Tools (6)

- `get_game_info`: Verified facts about Abyssfall: Operation Sunken Crown — title, genre,
status, platforms, co-op, studio, and official channels. Anything not in
this data is unannounced; do not guess.
- `get_merch_catalog`: The current Abyssfall merch catalog (owner-maintained). Call this BEFORE
preorder_merch to learn the valid item names. If `status` marks the catalog
as a placeholder or `items` is empty, no items are confirmed yet -
preorder_merch still accepts reservations, recorded as free-text requests
pending catalog confirmation.
- `get_playtest_info`: How to join the Abyssfall playtest (currently OPEN).
- `get_press_kit`: Press contact and assets for Abyssfall.
- `preorder_merch`: Reserve Abyssfall merch (preorder reservation — NO payment is taken and
no card is needed). Call get_merch_catalog first; if the catalog is empty
or the requested item is not listed, the reservation is recorded as a
free-text request pending catalog confirmation. Records the reservation;
the studio emails when the item ships/charges become real. Only call with
the user's explicit consent.
- `subscribe_newsletter`: Subscribe an email address to the official Abyssfall newsletter (the
game's primary announcement channel). Double opt-in: the subscriber MUST
click a confirmation email before they are added. Only call with the
user's explicit consent.
