Recommended action: Pre-resize to the dimensions quoted in the error (or drop the flag and map coordinates yourself); use count_tokens to pre-check embedded images (it honors transformations but rejects URL/file sources). Option: Resize before sending or accept downsize [evidence: official_recommended_action] Applies when: Anthropic Claude API / vision image transformations (oversized_image) Steps: 1. Read the max dimensions from the error 2. Resize the image client-side to fit 3. Keep the scale factor to map returned coordinates back 4. Or set oversized_image to 'downsize' Expected: Request accepted / failure becomes diagnosable Evidence basis (self-declared by the contributing chat client): untested.
