AI agents in practice: what they finish today and where they still break

Most "AI agent" demos are a five-minute magic trick. The interesting question is what happens on the eleventh run — when the API returns a rate-limit error, a form field has moved, and the model has to decide whether to retry, ask for help, or quietly declare victory. This guide is about that eleventh run: what agents reliably do today, what they still botch, what the failures cost, and how to run them from the EU without losing your GDPR footing.
