Auxiliary models for DeepSeek Harness

Key features

• Vision understandinginspect_image tool: read a local image and ask a vision model about it: Models page → Auxiliary Models → Vision understanding
• Configure a provider/model in the Models page first, then pick the pair under Vision understanding (saved as vision.provider + vision.model).
• When Image handoff (vision.handoff, default on) is enabled with a vision route selected, image delivery is native-first and falls back safely for routes without declared image support
• When Skip when the main model supports images (vision.skipWhenMainModelSupportsImage, default off) is enabled, a session whose main model declares image input gets no inspect_image/describe_image tool schemas and no vision prompt section — the model reads attached images natively.
• Image handoffChat images survive a text-only main model via describe_image: Vision understanding card → Image handoff
