EU AI Act Compliance Technical Guide for AI Agent Developers

I've been shipping AI agents since 2023. First ones were simple - call an LLM, maybe hit an API, return a result. Nobody cared what they did internally. That's over. The EU AI Act enforcement date is August 2, 2026. If your agents process data belonging to EU residents, execute transactions, make recommendations that affect people's lives - you're in scope. The fines are real: up to 7% of global revenue or €35M, whichever is higher.
