What nobody tells you about building real AI agents?

The prompt's easy; orchestration's the beast. Expect 70% engineering on plumbing, not models — silent failures, tool routing, state management eat cycles.

How do you fix wrong tool selection in AI agents?

Force determinism: Pre-route obvious cases with rules/regex, validate outputs post-tool, fallback to precise handlers. Confidence != correctness.

Can keyword routing scale for production AI agents?

Absolutely — for 80% volume. Layer with lightweight ML for rest. Saves tokens, latency; proven in high-traffic bots.
