The original headline is: "I Run 1,000 Agents in Production. Here's What I Learned About Reliability"

Short summary

Production agent failures stem from reliability infrastructure, not intelligence. Author shares three proven patterns—output validation, idempotency guards, and circuit breakers—deployed across 1,000+ runs, achieving zero duplicates, zero failures, and 75% cost reduction. Provides code examples and open-source ARK library.

• •Agent hallucinations manifest as simulated tool calls without actual execution, leading to phantom transactions and cascading failures
• •Three critical patterns: output validation against schemas, idempotency guards for duplicate prevention (inspired by Stripe), circuit breakers with automatic fallback to secondary models
• •Real-world results: 1,000+ production runs with zero duplicate executions, zero unrecovered failures, and 75% reduction in wasted LLM costs
