Skills are new features: Building Skill-Centric Harness — Yogendra Miraje, FactSet
A skill is a capability you provide to an AI agent — essentially a short file (skill.md) with a name and description that serves as routing signals for the agent to select the right tool.
At small scales, a simple registry suffices, but as the system grows — over ten skills require search and embeddings, over a hundred require actual governance with ownership, testing, and review. Critically, skills without tests begin to malfunction when new models are released, and at enterprise scale, governing and reviewing skills is at least as important as writing them.
