Image Generation Skill

Generate illustration images for blog posts, documentation, and technical articles. The workflow is provider-aware:

Codex built-in path first — when the current agent is Codex and the built-in image_gen tool is available, use it directly. This path does not require OPENAI_API_KEY.

OpenAI API fallback — outside Codex, or when the built-in tool is unavailable, use the local script with OPENAI_API_KEY if present.

Gemini fallback — if OpenAI API generation is unavailable or fails, use the same script with GEMINI_API_KEY and the existing Gemini image model.

Load provider-specific references only when needed:

Codex built-in path: references/codex-built-in.md

OpenAI API fallback: references/openai-api.md

Gemini fallback: references/gemini-api.md
