## What it does

The skill turns an image idea into a detailed generation prompt, improves existing prompts, and produces alternative versions. It adapts the format to the target service: Google Gemini (Nano Banana) gets conversational descriptions, while Midjourney, Stable Diffusion, DALL-E, and Leonardo.ai receive platform-oriented guidance.

Its workflow covers intent detection, prompt construction, component explanations, and suggestions for later edits. Reference files include `references/prompt-library.md`, `references/keywords-reference.md`, and `references/platform-specific.md`, which support category-specific and platform-specific requests.

When no platform is named, the skill targets Google Gemini (Nano Banana). Name Midjourney or Stable Diffusion explicitly when you need their format and parameters.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add manzxiao/text-to-image-prompt-optimizer --skill text-to-image-prompt-optimizer -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/text-to-image-prompt-optimizer/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/text-to-image-prompt-optimizer/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add manzxiao/text-to-image-prompt-optimizer --skill text-to-image-prompt-optimizer -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/text-to-image-prompt-optimizer/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add manzxiao/text-to-image-prompt-optimizer --skill text-to-image-prompt-optimizer -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/text-to-image-prompt-optimizer/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install manzxiao/text-to-image-prompt-optimizer text-to-image-prompt-optimizer
```

2. **Manually: put the files in place**
- File: `.github/skills/text-to-image-prompt-optimizer/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add manzxiao/text-to-image-prompt-optimizer --skill text-to-image-prompt-optimizer -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/manzxiao/text-to-image-prompt-optimizer
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/text-to-image-prompt-optimizer/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add manzxiao/text-to-image-prompt-optimizer --skill text-to-image-prompt-optimizer -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/manzxiao/text-to-image-prompt-optimizer/tree/HEAD/SKILL.md

## When to use it
- create a prompt for an AI-generated image
- rewrite an existing image description
- produce prompt variations in different styles
- adapt a request for Gemini or Midjourney
- explain the parts of an image prompt

## Example prompts
- Create a Google Gemini prompt for a rainy city street at night.
- Improve this prompt for Midjourney and give me several variations.
- Rewrite this scene for Stable Diffusion with suitable parameters.

# AI Image Prompt Optimizer

Generate professional, optimized prompts for AI image generation tools with **primary support for Google Gemini (Nano Banana)**, plus Midjourney, Stable Diffusion, DALL-E, Leonardo.ai, and others.

## Core Workflow

When a user requests prompt generation or optimization:

1. **Understand the intent**
   - Identify the core subject and desired outcome
   - Ask clarifying questions ONLY if the request is extremely vague
   - Default to reasonable assumptions rather than over-questioning

2. **Generate comprehensive prompts**
   - **Primary format: Google Gemini (Nano Banana)** - Use conversational, natural language with photographic/cinematic terminology
   - Provide multiple variations (2-3) with different styles or approaches
   - Include both English (primary) and Chinese translations
   - For Gemini: Use clear, descriptive sentences rather than keyword lists
   - For other platforms: Structure using formula `[Subject] + [Environment] + [Style] + [Lighting] + [Composition] + [Quality]`

3. **Include platform-specific optimizations**
   - **Gemini (Nano Banana) - PRIMARY**: Clear conversational prompts with photographic/cinematic language, semantic positive descriptions
   - Midjourney (secondary): Add `--ar`, `--s`, `--q`, etc. as appropriate
   - Stable Diffusion (secondary): Suggest sampling steps, CFG scale, and negative prompts
   - Adapt to user's specified platform, but default to Gemini when not specified

4. **Explain and educate**
   - Break down each component of the prompt
   - Explain why specific keywords were chosen
   - Suggest modifications for different effects

5. **Provide actionable next steps**
   - Guide users on how to use the prompt
   - Suggest parameter tweaks for refinement
   - Offer to iterate based on results

## Output Format

Structure responses as follows (prioritize Gemini format):

```
## 🎨 Generated Prompts

### ⭐ Variation 1: Google Gemini (Nano Banana) - RECOMMENDED
**English (Conversational):**
