Nano Banana Pro OpenRouter

**Judgment:** A solid, focused skill for OpenRouter-based image generation (Nano Banana Pro / Gemini 3 Pro Image) that fits well into OpenClaw’s workflow for creating new images, especially when users explicitly request this model or OpenRouter image generation. **Strengths:** - Clean shell-script integration with clear CLI contract; works well in typical Unix-like OpenClaw environments (sh, curl, base64). - Thoughtful draft→iterate→final flow and resolution mapping (1K/2K/4K) tuned for cost/performance. - Sensible handling of API keys and base URLs via .env files and explicit flags, plus structured filename management. **Key Limitations / Risks:** - Only supports **new image generation**; no image editing or inpainting from input images in this shell version. - Depends on correct environment setup (OPENROUTER_API_KEY, OPENROUTER_BASE_URL, .env files); misconfiguration leads to hard failures and user prompts for keys. - Relies on OpenRouter/model-side safety and any higher-level OpenClaw policies; the skill itself does not implement additional content moderation. - Vulnerable to external API issues (quota, permissions, 403s), which may require users to change keys or accounts. **Recommended Scenarios:** - Use as the primary tool when a user asks to **generate an image** and mentions **Nano Banana Pro**, **Gemini 3 Pro Image**, or **OpenRouter image generation**. - Prefer this skill for workflows that benefit from rapid, low-res drafts followed by a high-res final output. - Avoid when the user needs **image editing**, fine-grained model switching beyond Nano Banana Pro, or when the environment lacks required CLI tools or valid OpenRouter credentials.
