Start with workflows, not agents

Prefer the simplest thing that works — a single call, then a fixed workflow of composable steps, and only a fully autonomous agent when flexibility genuinely demands it.

WHY IT HOLDS

Agentic systems trade latency and cost for flexibility. Most tasks are well-defined enough that predictable code paths outperform, and simplicity keeps the system inspectable when it breaks.

WHAT IT PREVENTS

Over-engineered agent stacks that are expensive, slow, and impossible to debug.
