Topic
ai-agents
Agentic system design for production. Articles in this section cover planning, tool use, evals, reliability, memory, multi-agent orchestration, prompt patterns that survive iteration, and the rails (timeouts, budgets, audit logs) that keep agents from going off the rails. Posts compare frameworks where it matters and tell you when a framework is the wrong answer. If you are deciding between a skill, an MCP server, a subagent, and a hook, the comparison guides in this section are the place to start.
