jimliu
Generates images using official OpenAI and Google APIs via AI SDK. Supports text-to-image, reference images, aspect ratios, and quality presets. Use when user asks to "generate image with API", "use official API for images", "create image with OpenAI/Google", or needs API-based generation instead of browser-based.

# Check project-level first
test -f .baoyu-skills/baoyu-image-gen/EXTEND.md && echo "project"
# Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)

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 |

--provider specified β use it| 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
Supported: 1:1, 16:9, 9:16, 4:3, 3:4, 2.35:1
imageConfig.aspectRatioaspectRatio parameterSupports 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.
Custom configurations via EXTEND.md. See Preferences section for paths and supported options.

Use when you need to run Flow type checking, or when seeing Flow type errors in React code.
Use when you want to validate changes before committing, or when you need to check all React contribution requirements.
Use when feature flag tests fail, flags need updating, understanding @gate pragmas, debugging channel-specific test failures, or adding new flags to React.
Use when you need to check feature flag states, compare channels, or debug why a feature behaves differently across release channels.
