English | 锟斤拷锟斤拷锟斤拷锟斤拷

An experimental DeepSeek Harness
plugin that lets a text-only DeepSeek main agent accept images directly from
the DSH chat composer.

DSH image attachment -> vision model description -> deepseek-official

The plugin adds a separate deepseek-vision route. Image analysis runs through
an existing provider from DSH's Models settings; the official DeepSeek adapter
still owns the main conversation, reasoning, streaming, tools, and retries.

Compatibility

• DSH 0.1.0-rc.6
• Node.js 24+
• mcp-vision-bridge 0.2.7

Other versions may work but have not been tested.

Install

dsh plugin --profile web add github:mochgolf/dsh-deepseek-vision-router

1. Open Settings 锟斤拷 Models and add or reuse an image-capable provider. Its
   endpoint and credential stay owned by the Models page.
2. Open Settings 锟斤拷 Plugins 锟斤拷 DeepSeek Vision, select that provider, and
   save the vision model. The model field defaults to mimo-v2.5 but accepts
   any model ID exposed by the selected provider.

Provider additions, edits, and removals remain in Settings 锟斤拷 Models. The
plugin stores only visionProvider and visionModel in DSH's native settings
namespace and applies changes to the next image request without a restart.

Select DeepSeek + Vision in DSH's model menu. New sessions can use it as
their default provider; existing sessions retain their recorded provider until
switched.

Security and privacy

• Provider endpoints and credentials remain managed by DSH's Models settings;
  this plugin never copies or stores them.
• Image bytes are sent to the configured vision provider; DeepSeek receives the
  resulting text description, not the pixels.
• Descriptions are marked as untrusted image content before reaching DeepSeek,
  so text visible inside an image is not promoted to system instructions.
• Successful descriptions use a bounded, process-local cache.

Limitations

• The cache is not persisted across DSH restarts.
• The analysis prompt comes from an internal mcp-vision-bridge module; an
  upstream directory change may require a compatibility update.
• This is a preprocessing bridge, not native DeepSeek multimodality.
