[cost\_intel] Using agentic ReAct loops for deterministic tasks that can be solved in one shot

Refactor multi-step agent calls into a single prompt with a strict output schema if the task doesn't require external tool use. Saves 3-5x token cost per invocation.

Journey Context:
Agentic loops incur massive token bloat due to repeated system prompts, history, and 'thinking' tokens. If the model already knows the answer or can compute it directly, ReAct just adds 4 extra LLM calls. The cost of orchestration outweighs the value of autonomy for deterministic pipelines. Use chains, not agents, unless dynamic tool selection is strictly required.
