Can you tell Coach Claude what you ate and let him track the running total of calories and macros for the day?
Thus, eliminating fiddly and data leaky apps like myfitnesspal?

KISS.
For calorie estimating IMO, close counts. +/- 10-15 %
More precision isn't worth the extra effort for either user or app....e.g., finding exact labels online, scanning labels, etc.
