Agent Skills
Agent skills let humans organize, distribute, discover, and compose an agent’s capabilities. A skill is typically a markdown file, with optional scripts, references, and evals bundled alongside it.
Think of an agent skill as programming in natural language, written in markdown. It can hold knowledge, workflow logic, guardrails, required tools — basically anything.
Some outstanding skills:
- autoresearch instructs an agent to tirelessly tune models. It defines a workflow — really a loop — and states plainly what the agent can edit and what it can’t.
- img2threejs turns an image into a 3D model. It defines a workflow with heavy guardrails at every stage.
- superpowers defines a software development lifecycle. It has an opinionated, mandatory way to deliver software.
You probably already do some of this by hand. Just write it down, name the file SKILL.md, and let the agent pick it up. It’s that simple.
