DeepSeek Harness Plugin: dsh-vision-autoswitch — Automatically Switches to a Vision Model on Image Input, Then Reverts After the Turn Ends

`dsh-vision-autoswitch` is a DeepSeek Harness plugin maintained by CultOfLuna, designed to eliminate the cumbersome process of manually switching models in multimodal conversations. When it detects that an input contains images, the plugin automatically routes the current turn to `deepseek-v4-flash-vision-exp` and switches back to the user’s originally selected model after processing. It supports real-time display of the current model, leaves text-only turns unchanged, and requires manual installation by editing the configuration file. Its automated routing effectively lowers the barrier to using multimodal conversations.
