--- name: baoyu-image-gen description: AI image generation with OpenAI, Google, OpenRouter, DashScope, Jimeng, Seedream and Replicate APIs. Supports text-to-image, reference images, aspect ratios, and batch generation from saved prompt files. Sequential by default; use batch parallel generation when the user already has multiple prompts or wants stable multi-image throughput. Use when user asks to generate, create, or draw images. version: 1.56.3 metadata: openclaw: homepage: https://github.com/JimLiu/baoyu-skills#baoyu-image-gen requires: anyBins: - bun - npx --- # Image Generation (AI SDK) Official API-based image generation. Supports OpenAI, Google, OpenRouter, DashScope (阿里通义万象), 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 `${BUN_X}` runtime: if `bun` installed → `bun`; if `npx` available → `npx -y bun`; else suggest installing bun ## Step 0: Load Preferences ⛔ BLOCKING **CRITICAL**: This step MUST complete BEFORE any image generation. Do NOT skip or defer. Check EXTEND.md existence (priority: project → user): ```bash # macOS, Linux, WSL, Git Bash test -f .baoyu-skills/baoyu-image-gen/EXTEND.md && echo "project" test -f "${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-image-gen/EXTEND.md" && echo "xdg" test -f "$HOME/.baoyu-skills/baoyu-image-gen/EXTEND.md" && echo "user" ``` ```powershell # PowerShell (Windows) if (Test-Path .baoyu-skills/baoyu-image-gen/EXTEND.md) { "project" } $xdg = if ($env:XDG_CONFIG_HOME) { $env:XDG_CONFIG_HOME } else { "$HOME/.config" } if (Test-Path "$xdg/baoyu-skills/baoyu-image-gen/EXTEND.md") { "xdg" } if (Test-Path "$HOME/.baoyu-skills/baoyu-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 | |------|----------| | `.baoyu-skills/baoyu-image-gen/EXTEND.md` | Project directory | | `$HOME/.baoyu-skills/baoyu-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, OpenRouter, Replicate, 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 # 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 # 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 `, `-p` | Prompt text | | `--promptfiles ` | Read prompt from files (concatenated) | | `--image ` | Output image path (required in single-image mode) | | `--batchfile ` | JSON batch file for multi-image generation | | `--jobs ` | Worker count for batch mode (default: auto, max from config, built-in default 10) | | `--provider google\|openai\|openrouter\|dashscope\|jimeng\|seedream\|replicate` | Force provider (default: auto-detect) | | `--model `, `-m` | Model ID (Google: `gemini-3-pro-image-preview`; OpenAI: `gpt-image-1.5`; OpenRouter: `google/gemini-3.1-flash-image-preview`; DashScope: `qwen-image-2.0-pro`) | | `--ar ` | Aspect ratio (e.g., `16:9`, `1:1`, `4:3`) | | `--size ` | Size (e.g., `1024x1024`) | | `--quality normal\|2k` | Quality preset (default: `2k`) | | `--imageSize 1K\|2K\|4K` | Image size for Google/OpenRouter (default: from quality) | | `--ref ` | Reference images.

CLI flag: `--model ` 2. EXTEND.md: `default_model.[provider]` 3. Env var: `_IMAGE_MODEL` (e.g., `GOOGLE_IMAGE_MODEL`) 4. Built-in default **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]` - Show switch hint: `Switch model: --model | EXTEND.md default_model.[provider] | env _IMAGE_MODEL` ### DashScope Models Use `--model qwen-image-2.0-pro` or set `default_model.dashscope` / `DASHSCOPE_IMAGE_MODEL` when the user wants official Qwen-Image behavior. Official DashScope model families: - `qwen-image-2.0-pro`, `qwen-image-2.0-pro-2026-03-03`, `qwen-image-2.0`, `qwen-image-2.0-2026-03-03` - Free-form `size` in `宽*高` format - Total pixels must stay between `512*512` and `2048*2048` - Default size is approximately `1024*1024` - Best choice for custom ratios such as `21:9` and text-heavy Chinese/English layouts - `qwen-image-max`, `qwen-image-max-2025-12-30`, `qwen-image-plus`, `qwen-image-plus-2026-01-09`, `qwen-image` - Fixed sizes only: `1664*928`, `1472*1104`, `1328*1328`, `1104*1472`, `928*1664` - Default size is `1664*928` - `qwen-image` currently has the same capability as `qwen-image-plus` - Legacy DashScope models such as `z-image-turbo`, `z-image-ultra`, `wanx-v1` - Keep using them only when the user explicitly asks for legacy behavior or compatibility When translating CLI args into DashScope behavior: - `--size` wins over `--ar` - For `qwen-image-2.0*`, prefer explicit `--size`; otherwise infer from `--ar` and use the official recommended resolutions below - For `qwen-image-max/plus/image`, only use the five official fixed sizes; if the requested ratio is not covered, switch to `qwen-image-2.0-pro` - `--quality` is a baoyu-image-gen compatibility preset, not a native DashScope API field. Mapping `normal` / `2k` onto the `qwen-image-2.0*` table below is an implementation inference, not an official API guarantee Recommended `qwen-image-2.0*` sizes for common aspect ratios: | Ratio | `normal` | `2k` | |-------|----------|------| | `1:1` | `1024*1024` | `1536*1536` | | `2:3` | `768*1152` | `1024*1536` | | `3:2` | `1152*768` | `1536*1024` | | `3:4` | `960*1280` | `1080*1440` | | `4:3` | `1280*960` | `1440*1080` | | `9:16` | `720*1280` | `1080*1920` | | `16:9` | `1280*720` | `1920*1080` | | `21:9` | `1344*576` | `2048*872` | DashScope official APIs also expose `negative_prompt`, `prompt_extend`, and `watermark`, but `baoyu-image-gen` does not expose them as dedicated CLI flags today. Official references: - [Qwen-Image API](https://help.aliyun.com/zh/model-studio/qwen-image-api) - [Text-to-image guide](https://help.aliyun.com/zh/model-studio/text-to-image) - [Qwen-Image Edit API](https://help.aliyun.com/zh/model-studio/qwen-image-edit-api) ### OpenRouter Models Use full OpenRouter model IDs, e.g.: - `google/gemini-3.1-flash-image-preview` (recommended, supports image output and reference-image workflows) - `google/gemini-2.5-flash-image-preview` - `black-forest-labs/flux.2-pro` - Other OpenRouter image-capable model IDs Notes: - OpenRouter image generation uses `/chat/completions`, not the OpenAI `/images` endpoints - If `--ref` is used, choose a multimodal model that supports image input and image output - `--imageSize` maps to OpenRouter `imageGenerationOptions.size`; `--size ` is converted to the nearest OpenRouter size and inferred aspect ratio when possible ### Replicate Models Supported model formats: - `owner/name` (recommended for official models), e.g. `google/nano-banana-pro` - `owner/name:version` (community models by version), e.g. `stability-ai/sdxl:` Examples: ```bash # Use Replicate default model ${BUN_X} {baseDir}/scripts/main.ts --prompt "A cat" --image out.png --provider replicate # Override model explicitly ${BUN_X} {baseDir}/scripts/main.ts --prompt "A cat" --image out.png --provider replicate --model google/nano-banana ``` ## Provider Selection 1. `--ref` provided + no `--provider` → auto-select Google first, then OpenAI, then OpenRouter, then Replicate (Jimeng and Seedream do not support reference images) 2. `--provider` specified → use it (if `--ref`, must be `google`, `openai`, `openrouter`, or `replicate`) 3. Only one API key available → use that provider 4. Multiple available → default to Google ## Quality Presets | Preset | Google imageSize | OpenAI Size | OpenRouter size | Replicate resolution | Use Case | |--------|------------------|-------------|-----------------|----------------------|----------| | `normal` | 1K | 1024px | 1K | 1K | Quick previews | | `2k` (default) | 2K | 2048px | 2K | 2K | Covers, illustrations, infographics | **Google/OpenRouter imageSize**: Can be overridden with `--imageSize 1K|2K|4K` ## Aspect Ratios Supported: `1:1`, `16:9`, `9:16`, `4:3`, `3:4`, `2.35:1` - Google multimodal: uses `imageConfig.aspectRatio` - OpenAI: maps to closest supported size - OpenRouter: sends `imageGenerationOptions.aspect_ratio`; if only `--size ` is given, aspect ratio is inferred automatically - Replicate: passes `aspect_ratio` to model; when `--ref` is provided without `--ar`, defaults to `match_input_image` ## Generation Mode **Default**: Sequential generation. **Batch Parallel Generation**: When `--batchfile` contains 2 or more pending tasks, the script automatically enables parallel generation. | Mode | When to Use | |------|-------------| | Sequential (default) | Normal usage, single images, small batches | | Parallel batch | Batch mode with 2+ tasks | Execution choice: | Situation | Preferred approach | Why | |-----------|--------------------|-----| | One image, or 1-2 simple images | Sequential | Lower coordination overhead and easier debugging | | Multiple images already have saved prompt files | Batch (`--batchfile`) | Reuses finalized prompts, applies shared throttling/retries, and gives predictable throughput | | Each image still needs separate reasoning, prompt writing, or style exploration | Subagents | The work is still exploratory, so each image may need independent analysis before generation | | Output comes from `baoyu-article-illustrator` with `outline.md` + `prompts/` | Batch (`build-batch.ts` -> `--batchfile`) | That workflow already produces prompt files, so direct batch execution is the intended path | Rule of thumb: - Prefer batch over subagents once prompt files are already saved and the task is "generate all of these" - Use subagents only when generation is coupled with per-image thinking, rewriting, or divergent creative exploration Parallel behavior: - Default worker count is automatic, capped by config, built-in default 10 - Provider-specific throttling is applied only in batch mode, and the built-in defaults are tuned for faster throughput while still avoiding obvious RPM bursts - You can override worker count with `--jobs ` - Each image retries automatically up to 3 attempts - Final output includes success count, failure count, and per-image failure reasons ## Error Handling - Missing API key → error with setup instructions - Generation failure → auto-retry up to 3 attempts per image - Invalid aspect ratio → warning, proceed with default - Reference images with unsupported provider/model → error with fix hint ## Extension Support Custom configurations via EXTEND.md.
