--- schema: 1 type: video title: >- Skills are new features: Building Skill-Centric Harness — Yogendra Miraje, FactSet description: >- Since skills were open sourced, Yogendra Miraje's team at FactSet stopped thinking about shipping features and started thinking about shipping skills. A skill is a capability you hand the agent, and its heart is a short skill.md whose name and description are really routing signals: get them distinct and the agent triggers the right one, blur them and it fires the wrong skill or none at all. He walks through a minimal skill registry, progressive disclosure so the agent only loads what it needs, and trigger words, like asking for a PDF versus an HTML report, that decide which skill runs. The harder lessons show up at scale. Skills without evals drift, because a new model quietly stops obeying them, so he treats skills as contracts you test. Past ten skills you need search and embeddings to keep the library coherent; past a hundred you need real governance, admission, ownership, periodic audits, change management, and a human deciding whether a skill should exist at all. His close is that skills are the interface to your agentic products, and at enterprise scale governing them matters as much as writing them.
