Don't Build "Hope It Works" Agents

The author criticizes "hope it works" AI agents that directly connect system prompts to external APIs: they might pass tests but could perform erroneous actions like wrong refunds in production due to hallucinations.
They advocate adding a Self-Reflection / Internal Eval layer between Prompt -> Generate -> Execute: first generating a draft action, then having a model or rule check for core constraint violations before finally executing the tool call. While this adds slight latency, it significantly improves predictability and prevents rogue API calls.
The author also mentioned that their startup, Langoedge, is building this kind of deterministic orchestration engine, and promised to share insights on designing self-reflective eval loops, state handoffs, and trusting agents in production.
