dsh-vision-fallback: Add a "Vision Proxy" Toggle to DeepSeek Harness Sessions
The DSH Harness plugin `dsh-vision-fallback` provides visual capabilities for text-only sessions. Through a “vision proxy” toggle, it automatically forwards requests containing images to OpenAI-compatible vision providers, while plain-text requests are routed to the original model unchanged. The plugin supports multi-provider configuration, direct forwarding of original images, and streaming responses, although only some scenarios have been validated and it remains dependent on DSH’s internal APIs during development.

dsh-vision-fallback is an MIT-licensed plugin for DSH, maintained by 1HelloMan1. It is designed to address the gap where the main model supports text-only while the chat interface contains images. Through a plugin-based approach at the request layer, it automatically delegates images to a fixed vision model, converts them into hidden text context to return to the main model, while preserving the original images in the UI. This plugin is compatible with DSH versions 0.1.2-alpha.3 to 0.1.2-alpha.5 and requires a Node.js environment of at least 22.13.0. Its core features include automatically handling MCP/ACP persistent attachments and PTC nested images while preserving order; and supporting the configuration of the vision model and Base URL via the Web settings page or settings.yaml.
