My first headline finding turned out to be an infrastructure bug masquerading as agent behavior. This post is about what agents actually fail at in production, and the discipline it takes to not fool yourself with production data.Sat, 30 May 2026 18:00:00 GMThttps://hugo.im/posts/pt/20260530-mast-production-agent-failurespt/https://hugo.im/posts/pt/20260530-mast-production-agent-failurespt/Apliquei a taxonomia de falhas MAST a 639.000 passos de execução de agentes de IA rodando em produção por cinco meses.
