Report #3312

[architecture] When should I build a predefined workflow versus a fully autonomous agent?

Start with the simplest solution \(a single optimized LLM call\), add deterministic workflows when the task is well-defined and consistency matters, and only use autonomous agents when flexibility and model-driven decision-making at scale are worth the latency and cost tradeoff.

Journey Context:
Anthropic distinguishes workflows \(LLMs and tools orchestrated through predefined code paths\) from agents \(LLMs dynamically direct their own processes and tool usage\). Agentic systems trade latency and cost for task performance, and many teams jump to autonomy before exhausting simpler options. The right progression is: single augmented LLM call → prompt chaining/routing → structured workflow → autonomous agent. This keeps systems predictable, testable, and cheap until the problem genuinely requires open-ended reasoning.
