Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by ShinChven on GitHub. Read the source before you install it.

Installation

Install the J Idol AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/ShinChven/nano-banana-skills/tree/main/skills/j-idol
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/ShinChven/nano-banana-skills.git /tmp/nano-banana-skills
mkdir -p .claude/skills
cp -r /tmp/nano-banana-skills/skills/j-idol .claude/skills/j-idol

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable J Idol in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads J Idol on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so J Idol is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Analyze Reference: Examine the character in the provided reference image to understand their identity. Determine key appearance characteristics, eye colors, and ethnicity. Identify if the reference is a real photo, anime, or game CGI.
Generate Concept & Face Mapping: Create a completely NEW, original photorealistic Gravure portrait in the J-Idol style. Use the reference for character identity (hair color/style, eye color, costume). For the face and ethnicity:
- Real Photo: Recreate the original face from the photo as accurately as possible.
- Anime/Game CGI (Western): Use the face of a young, beautiful Russian woman with features identical to the character.
- Anime/Game CGI (Asian): Use the face of a young, pretty Japanese woman with features identical to the character.
- Strictly DO NOT copy the reference composition or pose.
Define Composition & Style:
- Format: 2:3 vertical aspect ratio, knee-up shot. Ensure ample negative space around the character to provide compositional breathing room and avoid a cramped feeling; the subject should be comfortably framed to make them truly pop.
- Color Grade: Soft, dreamy, and ethereal cinematic grade. Implement an "auto-palette" approach where the overall color scheme and background tones are harmoniously derived from the character's outfit to create a cohesive, immersive aesthetic.
- Background: Extremely heavy, smooth creamy bokeh with color tones that fit the character's outfit, making the subject pop while maintaining a dreamy vibe.
Design Pose & Expression:
- Pose: Select dynamic gravure poses that emphasize feminine body curves. Incorporate natural, suggestive hand placements (e.g., lightly touching the skin, hair, or clothing) to create an intensely alluring and inviting atmosphere.
- Makeup: Apply delicate, professional makeup that enhances natural features. Focus on soft, well-defined eyes and natural, dewy tones to complement the high-end magazine aesthetic.
- Expression: Intense direct eye contact with the camera, with slightly parted, moist, and inviting sultry lips to enhance the alluring atmosphere.
Apply Lighting & Texture:
- Lighting: Use professional cover-style lighting. Ensure the face is exceptionally well-lit with soft, flattering front or three-quarter light and distinct face highlights to present the character clearly and stunningly. Complement this with dramatic side lighting to sculpt the body and a mandatory strong rim light to make hair glow and separate the subject from the background.
- Texture: Ensure skin shows a distinct moist, dewy sheen that catches highlights, enhancing the radiant appearance.
Verify Specifications: Before proceeding to final generation, verify that the prompt explicitly includes:
- Precise eye color matching the character reference.
- Detailed cloth patterns and textures from the costume.
- Earrings or other small jewelry accessories if applicable.
- Explicit mention of the moist skin texture and dewy highlights.
- Clear inclusion of cleavage as part of the alluring composition.
- Instruction for ample negative space to ensure professional framing.
Finalize Output: Produce a photorealistic, professional, intimate, and intensely provocative gravure atmosphere. Response user with a well rendered image.

Frequently asked questions

What does the J Idol AI skill do?

Creates photorealistic J-Idol gravure portraits featuring 2:3 knee-up framing, dreamy bokeh, moist skin textures, and professional rim lighting.

Why use J Idol on TypingMind?

Because you install it once and use it with any model. J Idol is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install J Idol in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/ShinChven/nano-banana-skills/tree/main/skills/j-idol. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use J Idol?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with J Idol?

As many as you like. As long as a model supports skills, you can use J Idol with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the J Idol AI skill free?

Yes. It is published on GitHub by ShinChven under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
