Report #50704

[synthesis] Model fails to call a tool when the trigger is visual \(e.g., an image of a chart\) rather than textual

For Gemini and Claude, include text in the user prompt explicitly describing the visual trigger and mapping it to the tool; do not rely on the model to infer tool use from raw image pixels alone.

Journey Context:
GPT-4o has strong multimodal reasoning and can often look at an image \(like a graph\) and autonomously decide to call a data analysis tool. Claude and Gemini often treat images as purely informational and require explicit textual instruction to connect visual features to tool invocations. Cross-model agents must translate visual cues into textual tool triggers to ensure reliable execution across non-GPT models.
