Agent Skills: Your system prompt is not a knowledge base
What the format is, and the gap an SDK has to fill
Written by
Senior Consultant @ Microsoft | Cloud x AI Apps
Hi there! 👋 I'm a Senior Consultant at Microsoft, where I architect and build cloud-native distributed systems, including API-first platforms and intelligent applications in Python and .NET, primarily on Azure. Most of it runs on Kubernetes, with DevOps holding it together. More recently my focus has been agentic systems and orchestration, particularly with Microsoft Agent Framework and LangGraph. I write up the things that turned out harder than they looked, and what building them taught me.

Your catalog still ships in context every turn, so fifteen skills with when-to-use lists rebuild a smaller 4000-token prompt. Names first, descriptions only when a name looks relevant, would cut that leftover load. Those descriptions are tokens you pay on turns that never need them.
