Attack Cooldown Sync
by catgirljade
Attack Cooldown Sync corrects the attack cooldown display on Fabric, where a delay after swapping items can otherwise look out of step with the server.
What it does
Swapping items can leave the attack speed shown on the client out of step with the server, most visibly on connections with high ping. The mod predicts the attack speed reset when an item is swapped, covering the delay until the server sends the attribute change packet. It is client-side only, so a server does not need it and players join without installing anything. Files are published for Fabric across five release versions, 1.20.4 – 26.1.2, and the code is open source under the GNU General Public License v3.0 or later.
Key features
Attack speed prediction
The client predicts the attack speed reset that follows an item swap, rather than waiting for the server.
Packet-gap coverage
The predicted value holds until the server sends the attribute change packet, which closes the visible delay.
High-ping correction
The desync is most noticeable at high ping, and this correction targets that case.

What the author says
Fixes the noticable desync of your attack cooldown when swapping items. When swapping items, your attack speed is not updated until the server sends the packet to change your attributes. This mod predicts the attack speed and sets it once you swap items to make up for the delay between server and client.
