vision

# vision Multi-provider vision tool. Call various vision models to describe images. Feed it a prompt + image path, get back a text description. ## When to use this tool If you can already see and understand the image yourself (native multimodal model), skip this tool — analyze it directly. A SessionStart hook normally announces this session's routing status up front. If that context isn't visible (e.g. compacted out of a long conversation, or the hook isn't installed), check before calling this tool: ```bash python vision.py --check-routing ``` - `native` → you already have native image understanding this session; don't call this tool. - `external` (default) → proceed with the quick start below. ## Quick start ```bash python vision.py [--provider <name>] <image_path> <prompt> ``` When `--provider` is omitted, the provider is resolved by: `--provider` flag > `VISION_PROVIDER` env > first API key found. ## Providers ### doubao (Volcengine Ark) - API key: `DOUBAO_API_KEY` - Default model: `doubao-seed-2-0-pro-260215` - Custom endpoint: `DOUBAO_BASE_URL` ### qwen (DashScope) - API key: `DASHSCOPE_API_KEY` - Default model: `qwen-vl-max` - Custom endpoint: `DASHSCOPE_BASE_URL` - Available models: `qwen-vl-max`, `qwen-vl-plus`, `qvq-max` ### deepseek (DeepSeek) - API key: `DEEPSEEK_API_KEY` - Default model: `deepseek-v4-flash-vision-exp` - Custom endpoint: `DEEPSEEK_BASE_URL` - Only `deepseek-v4-flash-vision-exp` accepts images — `deepseek-v4-flash` and `deepseek-v4-...
