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:

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.
