Pbetween: DSH Web UI AI Agent Pet Animation Middleware

Petween is an agent pet animation middleware designed specifically for the DeepSeek Harness Web UI. It processes a limited number of static images with a Motion Engine and automatically generates comic-style transitions and looping animations using algorithms, eliminating the need for a large preset library. The plugin supports multiple animation styles, state tracking, interactivity, and visual editing, and is extensible through an animation pack ecosystem. Currently, it must be installed by cloning from source, making it suitable for developers who want to improve the visual expressiveness of agents at low cost.
