The agent-facing image_generate tool only passes prompt + aspect_ratio to provider.generate() (see tools/image_generation_tool.py:953). The editing block (reference_images / edit_image kwargs) could never fire from the tool surface, and the xAI edits endpoint is /images/edits with a different payload shape anyway — not /images/generations as submitted. - Remove reference_images / edit_image kwargs handling from generate() - Remove matching test_with_reference_images case - Update docstring + plugin.yaml description to text-to-image only - Surface resolution in the success extras Follow-up to PR #14547. Tests: 18/18 pass.
