Traditional software engineering taught us to write the test first. For LLM applications, the equivalent is often: write the eval first. ✅ TDD for business logic, APIs, integrations, and data pipelines. ✅ Eval-driven development for prompts, RAG systems, agent workflows, and response quality. Before changing prompts, retrieval strategies, or agent logic, define what success looks like and measure against it. 🚀
