What is Millie?

**Millie** is a collection of reusable Agent Skills for AI coding tools.

Each Millie skill is a self-contained folder containing a `SKILL.md` entry point and, when needed, supporting:

references/
scripts/
templates/
schemas/
assets/
data/
evaluations/

Instead of repeatedly pasting large prompts into an AI coding agent, you install Millie once and let the agent load the relevant specialist instructions when the task calls for them.

Millie is designed around the open **Agent Skills** model used by multiple coding-agent ecosystems.
