Nanobanana Skill

This is a solid wrapper around Gemini's image models, specifically tuned for Nanobanana 2 with Google Search grounding and thinking summaries turned on by default. That's the main reason to use it: you get grounded visuals that can pull from live web data, which matters for anything that needs current references, product accuracy, or real-world composition cues. The skill handles both text-to-image generation and multi-reference editing, supports extreme aspect ratios like 1:8 and 21:9, and lets you pick between 512px ideation mode and 4K finals. The prompting guidance is unusually specific and production-focused, pushing you toward art-director-style briefs instead of vague requests. If you're doing marketing assets, product mockups, or anything where factual grounding improves output quality, this is a clean way to route those tasks to Gemini without manual CLI work.
