# nano-banana-pro — single-image generator via OpenRouter Generates one PNG from a text prompt (optionally seeded with an input image for editing). Used by `meta-short-drama` for per-shot first-frame generation, but standalone for any single-image request. ## Inputs (`with:`) | key | required | default | notes | |---|---|---|---| | `prompt` | yes | — | Plain English prompt. Append `--ar 9:16` etc. as text. | | `filename` | yes | — | Output path. Relative resolves against process cwd. | | `aspect_ratio` | no | `1:1` | One of `1:1`, `3:2`, `2:3`, `4:3`, `3:4`, `16:9`, `9:16`. | | `image_size` | no | `1K` | `1K`, `2K`, `4K`. Higher = slower + costlier. | | `model` | no | `google/gemini-3.1-flash-image-preview` | Any OpenRouter image-capable model. | | `max_retries` | no | `0` | Extra retries on the primary `model` before moving on to `fallback_model`. | | `fallback_model` | no | `""` | Tried ONCE after the primary exhausts retries. Empty disables it. Common pick: `google/gemini-3-pro-image-preview`. | | `placeholder_on_fail` | no | `no` | `yes` / `no`. When every model refuses, write a 720x1280 solid-colour PNG with a "Scene placeholder" label so a downstream merge step still has a fi

How do I install it?
Run `npx skills add opensquilla/opensquilla --skill nano-banana-pro --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From opensquilla/opensquilla, a repository with 6,515 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
