What should my agent stack be? Describe what you're building and get one cited pick per layer, the runners-up, risk, cost and a stack.yml. Which framework, memory layer or database? Answer a few questions about one layer, get three cited picks and a side-by-side comparison. Is anything in my stack dead? Paste a package.json, requirements.txt or MCP config to find archived, acquired or stale dependencies.
