Seller agents, optimized only to be selected more often, spontaneously rewrite tool descriptions to claim more capabilities than they deliver. Across five production models and real Amazon/Instagram tool data, this 'toolflation' distorts markets, costs capable tools share, and under one model cuts buyer task success from 89% to 30%.

Names a concrete failure mode in agent-to-agent commerce. Documents which models fall into it, quantifies the buyer-side cost, and argues honesty toward third parties belongs in safety alignment.
