Eval-Driven Development for AI Agents
Eval-driven development means writing evals before you build, iterating against them, and gating releases on results. How the loop works — and its limits.
For the builders: agent architectures and their failure modes, memory design, framework-specific testing guides, and the engineering workflows that make agents shippable.

A practical guide to agent memory — context windows, summarization, long-term stores — the failure modes of each, and how to test memory before users do.
A layered method for testing a LangGraph agent: unit-test nodes, verify routing and state, then run simulated users against the compiled graph.
The five common AI agent architecture patterns — single-loop, plan-then-execute, router, multi-agent — and the distinct ways each one breaks.
Building an AI agent got easy. Deploying AI agents to production is where it breaks. What proving your agent works actually requires, step by step.
