A bug in Anthropic's Claude Code extension for Visual Studio Code causes significant cost increases by re-processing images that fail to load. When an image cannot be processed, the extension incorrectly bills the user for cache creation instead of cache reading, leading to approximately a 12x increase in token cost per turn. This issue can rapidly deplete a session's budget, as demonstrated by a session's budget dropping from 100% to 15% in just three replies. A fix has been filed, and a workaround involves clearing the session immediately upon encountering the error. AI
