EXTEND.md Supports: Default provider | Default quality | Default aspect ratio
Usage
# Basic
npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "A cat" --image cat.png
# With aspect ratio
npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "A landscape" --image out.png --ar 16:9
# High quality
npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "A cat" --image out.png --quality 2k
# From prompt files
npx -y bun ${SKILL_DIR}/scripts/main.ts --promptfiles system.md content.md --image out.png
# With reference images (Google multimodal only)
npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "Make blue" --image out.png --ref source.png
# Specific provider
npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "A cat" --image out.png --provider openai
Options
| Option | Description |
|--------|-------------|
| --prompt <text>, -p | Prompt text |
| --promptfiles <files...> | Read prompt from files (concatenated) |
| --image <path> | Output image path (required) |
| --provider google\|openai | Force provider (default: google) |
| --model <id>, -m | Model ID |
| --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 (default: from quality) |
| --ref <files...> | Reference images (Google multimodal only) |
| --n <count> | Number of images |
| --json | JSON output |
Environment Variables
| Variable | Description |
|----------|-------------|
| OPENAI_API_KEY | OpenAI API key |
| GOOGLE_API_KEY | Google API key |
| OPENAI_IMAGE_MODEL | OpenAI model override |
| GOOGLE_IMAGE_MODEL | Google model override |
| OPENAI_BASE_URL | Custom OpenAI endpoint |
| GOOGLE_BASE_URL | Custom Google endpoint |
Load Priority: CLI args > env vars > <cwd>/.baoyu-skills/.env > ~/.baoyu-skills/.env
Provider Selection
--providerspecified → use it- Only one API key available → use that provider
- Both available → default to Google
Quality Presets
| Preset | Google imageSize | OpenAI Size | Use Case |
|--------|------------------|-------------|----------|
| normal | 1K | 1024px | Quick previews |
| 2k (default) | 2K | 2048px | Covers, illustrations, infographics |
Google 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 - Google Imagen: uses
aspectRatioparameter - OpenAI: maps to closest supported size
Parallel Generation
Supports concurrent image generation via background subagents for batch operations.
| Setting | Value | |---------|-------| | Recommended concurrency | 4 subagents | | Max concurrency | 8 subagents | | Use case | Batch generation (slides, comics, infographics) |
Agent Implementation:
# Launch multiple generations in parallel using Task tool
# Each Task runs as background subagent with run_in_background=true
# Collect results via TaskOutput when all complete
Best Practice: When generating 4+ images, spawn background subagents (recommended 4 concurrent) instead of sequential execution.
Error Handling
- Missing API key → error with setup instructions
- Generation failure → auto-retry once
- Invalid aspect ratio → warning, proceed with default
- Reference images with non-multimodal model → warning, ignore refs
Extension Support
Custom configurations via EXTEND.md. See Preferences section for paths and supported options.

GraphQL gives clients exactly the data they need - no more, no less. One endpoint, typed schema, introspection. But the flexibility that makes it powerful also makes it dangerous. Without proper controls, clients can craft queries that bring down your server. This skill covers schema design, resolvers, DataLoader for N+1 prevention, federation for microservices, and client integration with Apollo/urql. Key insight: GraphQL is a contract. The schema is the API documentation. Design it carefully.
