Pro Tips

Small moves that make the checklist easier to finish

Provider rate limits are a scheduled event, not an edge case. An agent with no fallback will stop mid-decision the first time the primary throttles, which in a finance workflow can leave risk unmanaged.
The dangerous retry is the one with a side effect. A timed-out order that retries and double-fills is far worse than a failed query, so idempotency is non-negotiable for trading agents.
Never let an LLM be the only thing standing between you and an open position. Deterministic logic must be able to manage existing risk even when the entire model chain is down.
