AWS bill spikes to $31 for 14 visitors; developer traces cost to own AI agent
A developer's free learning-path app, Clew Directive, had only 14 visitors but an AWS bill of $31. Investigation revealed the cost came from a separate AI agent project running on Claude Sonnet during a weekend sprint. The app itself uses cheaper Amazon Nova models and was not the source of the charges.

A cautionary tale about cloud cost attribution: the dashboard can mislead, and a single mislabeled model or forgotten agent can inflate bills far beyond what user traffic justifies.
