Description

I maintain a client-side mod called Shoulder Surfing: Iron Spells Integration, which currently works as expected.
It enables all features of this mod to function with Shoulder Surfing and also supports controller mods.

To achieve this, I need a client-side event that triggers before casting a spell — whether through the spellbook (quick cast or keybind) or a scroll item.
Currently, the available public API events are server-side only, requiring me to send a network packet to the client and handle it there. This is inefficient, introduces delay, and requires the mod to be installed on the server.

As a workaround, I used a mixin on internal classes of this mod, which is unreliable and prone to breaking changes after updates.
