[Bug] Excessive token consumption for image analysis tasks on Opus model

Bug Description
I prompted Claude Code for

[Image #3] commitment pattern is overflowing by 20px on iphone
⎿  [Image #3]

read an image and fix an overflow issue and it consumed 15% of my 5 hour usage on the 5x max plan.
I'm running Claude Code Opus 4.6 on medium effort
