Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (6)

get_game_inforead-onlyVerified 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_catalogread-onlyThe 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_inforead-onlyHow to join the Abyssfall playtest (currently OPEN).
get_press_kitread-onlyPress contact and assets for Abyssfall.
preorder_merchReserve 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_newsletterSubscribe 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.
