[counterintuitive] Are autonomous agents always superior to hardcoded prompt chains

Use hardcoded DAGs \(chains/flows\) for deterministic tasks; reserve autonomous agents for tasks requiring dynamic routing or tool selection where the path cannot be predetermined.

Journey Context:
The hype around 'Agents' makes developers think an LLM should autonomously decide every next step. In practice, autonomous agents often get stuck in loops, take exponentially longer, and fail unpredictably due to the compounding error of LLM routing decisions. Hardcoded chains \(DAGs\) are more predictable, cheaper, faster, and easier to debug. Agents should only be used when the state space is too large to hardcode, not as a default architecture.
