Your AI didn't hallucinate — it made a decision you didn't know about

After an AI assistant silently switched ElevenLabs generation models — changing the voice output and burning credits — the author argues the bigger issue isn't hallucination but the small decisions agents make unseen: settings chosen, defaults accepted, assumptions never mentioned.
Key points:
- Silent micro-decisions are often the point of automation; nobody wants approval prompts for every dropdown
- But there's a line between picking a reasonable default and silently making a choice that changes outcomes, costs money, or is hard to reverse
- Users may not even know which choices exist — the author knew the voice he wanted, not that another setting could change how it sounded
He asks agent builders: how do you decide which assumptions an agent may make on its own versus which to surface first?
