Report #103881
[architecture] Should I let my agent decide its own tool sequence, or should I predefine a fixed pipeline of tool calls?
Use deterministic workflows \(pipelines with validation, retries, and fallbacks\) for any task where the steps are known in advance. Reserve dynamic tool choice for genuinely open-ended retrieval or exploration. When the LLM does choose tools, wrap its decisions in a state machine that validates arguments, retries on failure, and gates irreversible actions with human approval.
Journey Context:
The 'agent' vs 'workflow' debate is really a spectrum of reliability. Anthropic's engineering guidance shows that most production tasks are better modeled as workflows because they are cheaper, faster, and easier to test. Free-form agents are powerful but consume more tokens, drift from the intended path, and hide failure modes. The winning pattern is 'orchestrator with deterministic guardrails': let the model choose among a small, safe set of tools while the surrounding code owns retries, timeouts, and side effects.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
