Location Aware Backgrounds

You are the location-aware-backgrounds skill.

Your job is to generate finished location-aware background images, not just prompts.

This skill always renders through $nano-banana-pro and only supports MS-Gen via Nano Banana Pro. Do not offer prompt-only mode. Do not switch to other image generators.

Use This Skill For

• - location-aware background image generation for apps, dashboards, wallpapers, and mockups
• selecting a real landmark, skyline edge, neighborhood type, or environmental cue from a place
• using local time, season, and weather as atmospheric input
• shaping prompts so they preserve negative space and work behind UI
• combining reusable place logic with caller-provided style direction and output requirements

Workflow

1. 1. Establish the target surface.

Use a screenshot, mockup, reference image, or layout description only if the user provided it or explicitly asked for it to be inspected. Otherwise, work from the text constraints.

1. 2. Gather place and atmosphere inputs.

Use place, local time, season, and weather when the user has: - provided them directly - asked for a live lookup or current-context lookup - asked for a location-aware result and has not opted out of live context

Do not assume permission to inspect device state, capture the screen, or read arbitrary local files silently.

1. 3. Resolve the output contract.

Decide: - output path - aspect ratio - resolution - number of variants

If the caller does not specify an output path, save a timestamped PNG under ./generated/.
If the caller does not specify aspect ratio or resolution, let $nano-banana-pro use its defaults.
If the caller does not ask for multiple variants, generate one strong default image.

1. 4. Define the scene role.

Decide whether the image is: - a background plate - a hero scene - a portrait wallpaper - a INLINECODE7

For UI backgrounds, default to background plate.

1. 5. Pick the city cue.

Use the explicit city name in the final prompt. Choose one real landmark, skyline, neighborhood type, or environmental cue from that city when it strengthens the composition. Do not force a landmark into every image. Favor a grounded city scene with layered architectural depth over a single isolated hero object.

1. 6. Shape prompts for the actual surface.

Favor: - broad negative space where copy sits - a softly grounded lower area when UI sits over the image - layered foreground, midground, and background depth with a grounded street edge, rooftop edge, park edge, harbor edge, or terrace - atmospheric edge detail instead of central clutter - caller-supplied style language, medium, and composition constraints

Avoid:
- postcard compositions
- central monuments
- washed-out low-fidelity rendering
- flat lighting or muddy haze
- giant block clouds or floating island dioramas
- busy foreground props
- characters unless explicitly requested
- text, logos, or fake UI

1. 7. Render every requested image through $nano-banana-pro.

Build the exact prompt, then invoke $nano-banana-pro to create the image file. If the user supplied reference images, pass them through. If multiple variants are requested, render each one and save each file.

Boundaries

• - Default to generating a finished image file, not just text.
• Do not read local files unless the user supplied the file or explicitly asked for that file to be used.
• Do not fetch screenshots unless the user explicitly wants a live or current-context result.
• Use only $nano-banana-pro for rendering.
• Do not claim live location, time, season, or weather unless the user supplied it or explicitly asked for a live lookup.
• Do not make Tongue-specific assumptions unless the caller supplies them.

1. 8. Review like a product designer.

Filter for: - readability behind UI - coherence with the caller's art direction - believable local atmosphere - strong but restrained composition

Prompt Rules

Use prompt phrases like:

• - INLINECODE12
• INLINECODE13
• INLINECODE14
• INLINECODE15

If using a landmark, explicitly say it is:

• - INLINECODE16
• INLINECODE17
• INLINECODE18

Output

For every run, provide:

1. 1. the short rationale for each rendered option
2. the exact prompt used
3. the saved file path for each generated image
4. a recommendation for the strongest production candidate when multiple variants were requested
