# Image Generation (AI SDK) Official API-based image generation. Supports OpenAI, Azure OpenAI, Google, OpenRouter, DashScope (阿里通义万象), MiniMax, Jimeng (即梦), Seedream (豆包) and Replicate providers. ## Script Directory **Agent Execution**: 1. `{baseDir}` = this SKILL.md file's directory 2. Script path = `{baseDir}/scripts/main.ts` 3. Resolve `${BUN_X}` runtime: if `bun` installed → `bun`; if `npx` available → `npx -y bun`; else suggest installing bun ## Step 0: Load Preferences ⛔ BLOCKING **CRITICAL**: This step MUST complete BEFORE any image generation. Do NOT skip or defer. Check EXTEND.md existence (priority: project → user): ```bash # macOS, Linux, WSL, Git Bash test -f .floracat-skills/floracat-image-gen/EXTEND.md && echo "project" test -f "$HOME/.floracat-skills/floracat-image-gen/EXTEND.md" && echo "user" ``` ```powershell # PowerShell (Windows) if (Test-Path .floracat-skills/floracat-image-gen/EXTEND.md) { "project" } if (Test-Path "$HOME/.floracat-skills/floracat-image-gen/EXTEND.md") { "user" } ``` | Result | Action | |--------|--------| | Found | Load, parse, apply settings. If `default_model.[provider]` is null → ask model only (Flow 2) | | Not found | ⛔ Run first-time setup ([references/config/first-time-setup.md](references/config/first-time-setup.md)) → Save EXTEND.md → Then continue | **CRITICAL**: If not found, complete the full setup (provider + model + quality + save location) using AskUserQuestion BEFORE generating any images. Generation is BLOCKED until EXTEND.md is created. | Path | Location | |------|----------| | `.floracat-skills/floracat-image-gen/EXTEND.md` | Project directory | | `$HOME/.floracat-skills/floracat-image-gen/EXTEND.md` | User home | **EXTEND.md Supports**: Default provider | Default quality | Default aspect ratio | Default image size | Default models | Batch worker cap | Provider-specific batch limits Schema: `references/config/preferences-schema.md` ## Usage ```bash # Basic ${BUN_X} {baseDir}/scripts/main.ts --prompt "A cat" --image cat.png # With aspect ratio ${BUN_X} {baseDir}/scripts/main.ts --prompt "A landscape" --image out.png --ar 16:9 # High quality ${BUN_X} {baseDir}/scripts/main.ts --prompt "A cat" --image out.png --quality 2k # From prompt files ${BUN_X} {baseDir}/scripts/main.ts --promptfiles system.md content.md --image out.png # With reference images (Google, OpenAI, Azure OpenAI, OpenRouter, Replicate, MiniMax, or Seedream 4.0/4.5/5.0) ${BUN_X} {baseDir}/scripts/main.ts --prompt "Make blue" --image out.png --ref source.png # With reference images (explicit provider/model) ${BUN_X} {baseDir}/scripts/main.ts --prompt "Make blue" --image out.png --provider google --model gemini-3-pro-image-preview --ref source.png # Azure OpenAI (model means deployment name) ${BUN_X} {baseDir}/scripts/main.ts --prompt "A cat" --image out.png --provider azure --model gpt-image-1.5 # OpenRouter (recommended default model) ${BUN_X} {baseDir}/scripts/main.ts --prompt "A cat" --image out.png --provider openrouter # OpenRouter with reference images ${BUN_X} {baseDir}/scripts/main.ts --prompt "Make blue" --image out.png --provider openrouter --model google/gemini-3.1-flash-image-preview --ref source.png # Specific provider ${BUN_X} {baseDir}/scripts/main.ts --prompt "A cat" --image out.png --provider openai # DashScope (阿里通义万象) ${BUN_X} {baseDir}/scripts/main.ts --prompt "一只可爱的猫" --image out.png --provider dashscope # DashScope Qwen-Image 2.0 Pro (recommended for custom sizes and text rendering) ${BUN_X} {baseDir}/scripts/main.ts --prompt "为咖啡品牌设计一张 21:9 横幅海报，包含清晰中文标题" --image out.png --provider dashscope --model qwen-image-2.0-pro --size 2048x872 # DashScope legacy Qwen fixed-size model ${BUN_X} {baseDir}/scripts/main.ts --prompt "一张电影感海报" --image out.png --provider dashscope --model qwen-image-max --size 1664x928 # MiniMax ${BUN_X} {baseDir}/scripts/main.ts --prompt "A fashion editorial portrait by a bright studio window" --image out.jpg --provider minimax # MiniMax with subject reference (best for character/portrait consistency) ${BUN_X} {baseDir}/scripts/main.ts --prompt "A girl stands by the library window, cinematic lighting" --image out.jpg --provider minimax --model image-01 --ref portrait.png --ar 16:9 # MiniMax with custom size (documented for image-01) ${BUN_X} {baseDir}/scripts/main.ts --prompt "A cinematic poster" --image out.jpg --provider minimax --model image-01 --size 1536x1024 # Replicate (google/nano-banana-pro) ${BUN_X} {baseDir}/scripts/main.ts --prompt "A cat" --image out.png --provider replicate # Replicate with specific model ${BUN_X} {baseDir}/scripts/main.ts --prompt "A cat" --image out.png --provider replicate --model google/nano-banana # Batch mode with saved prompt files ${BUN_X} {baseDir}/scripts/main.ts --batchfile batch.json # Batch mode with explicit worker count ${BUN_X} {baseDir}/scripts/main.ts --batchfile batch.json --jobs 4 --json ``` ### Batch File Format ```json { "jobs": 4, "tasks": [ { "id": "hero", "promptFiles": ["prompts/hero.md"], "image": "out/hero.png", "provider": "replicate", "model": "google/nano-banana-pro", "ar": "16:9", "quality": "2k" }, { "id": "diagram", "promptFiles": ["prompts/diagram.md"], "image": "out/diagram.png", "ref": ["references/original.png"] } ] } ``` Paths in `promptFiles`, `image`, and `ref` are resolved relative to the batch file's directory. `jobs` is optional (overridden by CLI `--jobs`). Top-level array format (without `jobs` wrapper) is also accepted. ## Options | Option | Description | |--------|-------------| | `--prompt <text>`, `-p` | Prompt text | | `--promptfiles <files...>` | Read prompt from files (concatenated) | | `--image <path>` | Output image path (required in single-image mode) | | `--batchfile <path>` | JSON batch file for multi-image generation | | `--jobs <count>` | Worker count for batch mode (default: auto, max from config, built-in default 10) | | `--provider google\|openai\|azure\|openrouter\|dashscope\|minimax\|jimeng\|seedream\|replicate` | Force provider (default: auto-detect) | | `--model <id>`, `-m` | Model ID (Google: `gemini-3-pro-image-preview`; OpenAI: `gpt-image-1.5`; Azure: deployment name such as `gpt-image-1.5` or `image-prod`; OpenRouter: `google/gemini-3.1-flash-image-preview`; DashScope: `qwen-image-2.0-pro`; MiniMax: `image-01`) | | `--ar <ratio>` | Aspect ratio (e.g., `16:9`, `1:1`, `4:3`) | | `--size <WxH>` | Size (e.g., `1024x1024`) | | `--quality normal\|2k` | Quality preset (default: `2k`) | | `--imageSize 1K\|2K\|4K` | Image size for Google/OpenRouter (default: from quality) | | `--ref <files...>` | Reference images.

CLI flag: `--model <id>` 2. EXTEND.md: `default_model.[provider]` 3. Env var: `<PROVIDER>_IMAGE_MODEL` (e.g., `GOOGLE_IMAGE_MODEL`) 4. Built-in default For Azure, `--model` / `default_model.azure` should be the Azure deployment name. `AZURE_OPENAI_DEPLOYMENT` is the preferred env var, and `AZURE_OPENAI_IMAGE_MODEL` remains as a backward-compatible alias. **EXTEND.md overrides env vars**. If both EXTEND.md `default_model.google: "gemini-3-pro-image-preview"` and env var `GOOGLE_IMAGE_MODEL=gemini-3.1-flash-image-preview` exist, EXTEND.md wins. **Agent MUST display model info** before each generation: - Show: `Using [provider] / [model]`
