Report #27576

[counterintuitive] Tool-calling \(ReAct\) agents are strictly superior to direct generation

Default to direct generation for simple tasks. Only introduce tool-calling loops when the task requires external data, dynamic computation, or multi-step state that cannot be resolved by the LLM's parametric memory.

Journey Context:
The hype around agentic loops makes developers wrap every prompt in a ReAct chain. This introduces massive latency, error propagation \(one bad tool call ruins the rest\), and cost. For coding tasks like 'write a standard CRUD endpoint,' direct generation is faster and more reliable. Agents should assess task complexity and choose the simplest execution path.
