[counterintuitive] Are agent loops with tool use always better than single prompts

Default to single-prompt or hardcoded chained-prompt workflows; only introduce agentic loops \(like ReAct\) when the task genuinely requires dynamic routing or external state, as agent loops suffer from compounding error rates and high latency.

Journey Context:
The hype around agents makes developers reach for autonomous loops for everything. However, each step in an agent loop has a failure probability, and these multiply. A 3-step agent with 95% step-accuracy has an 85% overall success rate. Monolithic or hardcoded chains are more predictable, cheaper, and faster for deterministic tasks. Agentic loops should be a last resort for highly dynamic tasks, not the default architecture.
