2 signals

Over-guardrailing AI agents can be as destructive as under-guardrailing - SaaStr's pitch deck grader went from working to 53% failure rate after adding 14 exception rules, each added to fix edge cases but collectively strangling the agent
Platform choice fundamentally shapes agent behavior beyond the spec - identical specifications deployed on Replit vs Lovable produced agents with different personalities, output volumes (3 vs 4 recommendations), and strategic approaches (cautious vs aggressive)
Production AI requires different thinking than development - the 'easy part' is building agents, the hard part is running them reliably at scale, as demonstrated by SaaStr's journey from -19% to +47% YoY revenue while managing 21+ agents
