persona-image-generator

为代理、个人头像以及“给我画个图”的请求生成风格化的人物/角色图像(单幅或多幅变体)。适用于用户要求生成图像/头像/人物概念、探索视觉风格,或希望获得一致的角色设定时使用。相较于仅依赖长文本描述的请求,此类技能更适合用于创意图像生成。

description: Generate stylized persona/character images (single or multi-variation) for agents, profile pictures, and "draw me" requests. Use when a user asks for an image/avatar/persona concept, visual style exploration, or consistent character sheets. Prefer this skill for creative image generation requests instead of long text-only descriptions.

Persona Image Generator

Generate a concrete image output (not just a prompt) for persona/avatar requests.

Workflow

  1. Extract intent in one line: subject + style + mood + output usage.
  2. Ask only missing essentials (max 3):
    • style (pixel-art, anime, cinematic, minimal, etc.)
    • framing (portrait, full-body, scene)
    • constraints (colors, outfit, symbols, no-go items)
  3. Create one strong base prompt + 2 variations.
  4. Invoke the configured image-generation capability (e.g., nano-banana-pro) and produce image outputs.
  5. Return:
    • generated image(s)
    • short caption per image
    • reusable final prompt text

Prompt template

Use this structure:

<subject>, <visual style>, <camera/framing>, <lighting>, <palette>, <mood>, <environment>, high detail, clean composition, no text watermark

Defaults

  • If user says "draw your persona":
    • subject: friendly AI assistant mascot
    • style: modern pixel-art or clean illustration
    • framing: portrait (head + shoulders)
    • mood: warm, competent, calm
  • Generate 3 variants unless user asks for 1.

Quality checks

Before finalizing, verify:

  • subject matches requested identity
  • style is clearly visible
  • no unwanted text/watermarks
  • output is usable as avatar/banner (if requested)

Output format

Provide concise output:

  1. Variant A/B/C + one-line style description
  2. Attach image(s)
  3. Prompt used: block for reuse/editing

Do not

  • Do not respond with prompt-only if user explicitly asked for generated images.
  • Do not over-question; proceed with sensible defaults when possible.
  • Do not include copyrighted character names unless user explicitly requests parody/fan style.
