## Overview

Create a new agent directory and `AGENT.md` file for Stencila. An agent is a directory containing an `AGENT.md` file with YAML frontmatter (configuration) and an optional Markdown body (system instructions). Agents live under `.stencila/agents/` (workspace) or `~/.config/stencila/agents/` (user).
