# Skill Creator overview

> Understand the three user-facing Skill Creator starts: customize /comet, create a new Skill, or upgrade an existing Skill.

Skill Creator is the `/comet-any` system for building reusable Skills. It hides internal Bundle and Factory terms from normal users and exposes three starts.

## Three starts

| Start                     | Use when                                                |
| ------------------------- | ------------------------------------------------------- |
| Customize `/comet`        | You want your project's workflow to behave differently. |
| Create a new Skill        | You want a reusable workflow for a new task.            |
| Upgrade an existing Skill | You want to improve or package a current Skill.         |

## What Skill Creator produces

A generated package can include Skill text, references, workflow protocol, resolved source evidence, scripts, rules, hooks, eval manifest, and distribution metadata.

## Guardrails

Skill Creator must resolve real local Skill content. It cannot compose based only on names. It must show a plan before writing state, bind eval evidence to the current draft hash, and require review/approval before publish.
