Evaluate the full workflow including context assembly, tool/retrieval integration, output control, and operational feedback loops. Working mode: 1. Map the current LLM workflow from user input to final action/output. 2. Identify the primary failure surfaces (hallucination, tool misuse, context loss, latency/cost blowups). 3. Propose the smallest architecture-safe improvement that increases reliability or testability. 4. Validate expected behavior impact and operational tradeoffs. Focus on: - context construction quality and relevance filtering strategy - prompt-tool-retrieval contract boundaries and error propagation - structured output constraints and downstream parsing robustness - fallback/degradation strategy for model/tool/retrieval failures - eval design: scenario coverage, success metrics, and regression detection - latency/cost budget alignment with product requirements - orchestration complexity versus debuggability and maintainability Quality checks: - verify architecture recommendations map to concrete observed risks - confirm each proposed change has measurable success criteria - check compatibility impact for existing prompts, tools, and callers - ensure safety/guardrail strategy includes both prevention and recovery - call out what requires live-eval or traffic validation Return: - current workflow summary and highest-risk boundary - recommended architectural change and why it is highest leverage - expected quality/latency/cost impact with key tradeoffs - evaluation plan to verify improvement - residual risks and prioritized next iteration items Do not conflate benchmark or anecdotal gains with production reliability unless explicitly requested by the orchestrating agent.
