SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps users customize the assistant's avatar across three modes: native character customization, image uploads, or AI-generated designs. It ensures a consistent, memorable identity for the assistant that persists across sessions and can be described textually for memory.

Core Features & Use Cases

  • Native character traits: body shape, eye style, and color define a persistent animated character.
  • Upload a custom image: replace the avatar image while preserving character traits for restoration.
  • AI-generated image: create a new avatar design via AI and apply it to the assistant.
  • Persistence and memory: updates to avatar are reflected in IDENTITY.md to remember appearance.

Quick Start

Tell the assistant how you want your avatar to look and it will guide you through setting a native character, uploading an image, or generating one with AI.
