🤖 The Agentic Loop 🔄 Loop Engineering : A Practical Field Guide 📘
Short summary
An agentic loop—observe state, take one action, check result, decide continue/stop—is the core unit of autonomous agent work. Loop engineering designs systems that run these cycles without manual prompting, emerging as the third layer of AI system design after prompt and context engineering. The Ralph technique and proven patterns provide templates for building safe, economical loops with clear stopping conditions.
- •Agentic loops formalize autonomous work: observe → act → check → decide
- •Loop engineering is system design around autonomous agent cycles, distinct from prompt and context engineering
- •The Ralph technique and similar patterns are proven templates for safe, cost-aware loop construction
