nano-banana skillA

nano-banana is agent-read markdown (skill) from mycelium-hq/ai-brain-starter: Use when the user asks to create or generate an image, visual, logo, thumbnail, infographic, product shot, hero image, OG image, blog/Substack header, sticker, portrait, or any text-to-image or image-generation task; edit a photo; compose multiple images; refine an image iteratively; set aspect ratio/resolution; or visualize real-time data (weather, stocks, news) with Gemini's Nano Banana Pro. Not for text generation, design feedback (design:design-critique), or template designs (Canva MCP)..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add mycelium-hq/ai-brain-starter/nano-banana@git:20260707.f0ac903
Exact content
mdr add mycelium-hq/ai-brain-starter/nano-banana@sha256:2df3aa86e332b86b

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
