# Nano Banana Pro Visual System AI-powered infographic generation for FirstMile/Xparcel presentations. Three proven prompt patterns with consistent visual language. ## When to Use - Creating presentation slides explaining shipping concepts - Building customer-facing explainer visuals - Generating internal training materials - Producing one-pagers and leave-behinds ## Skill Triggers - `"create infographic"` / `"create visual"` - `"nano banana"` / `"presentation slide"` - `"shipping explainer"` / `"rate card visual"` - `"customer journey"` / `"billing architecture"` ## Quick Start **Pick your pattern based on what you're explaining:** | Pattern | Use When | Example | |---------|----------|---------| | **Flow (Horizontal)** | Multi-step process with complexity reveal | Service → Routing → Rate Cards → Invoice | | **Layer (Vertical)** | System architecture, abstraction levels | Customer sees → We handle → Output | | **Stage (Horizontal)** | Simple customer journey, UX flows | Select → Rate → Label | **Then:** Load the pattern template from `references/` and customize. ## Visual Style Guide ### Color Palette | Color | Hex | Usage | |-------|-----|-------| | **Xparcel Green** | `#7CB342` | Primary accent, buttons, highlights, Select Network | | **FirstMile Navy** | `#1E3A5F` | Headers, National Network, secondary text | | **National Blue** | `#366092` | National rate card, coverage maps | | **Select Gold** | `#F5A623` | Select rate card accent, warnings | | **USPS Blue-Gray** | `#336699` | USPS elements | | **Background** | `#FFFFFF` | Primary background | | **Muted Gray** | `#F5F5F5` | Secondary sections, "behind the scenes" | ### Typography - **Headers:** Bold sans-serif (Inter, Helvetica Neue) - **Body:** Regular sans-serif, clean and readable - **Accent text:** ALL CAPS for section labels - **Numbers:** Large, prominent for rates/prices ### Icon Style - Flat, line-art icons - Consistent stroke weight - Green accent color - Chevrons for service levels (triple/double/single) ### Layout Principles 1. **Aspect Ratio:** 16:9 for all presentation slides 2. **Flow Direction:** Left-to-right or top-to-bottom (never mixed) 3. **Complexity Treatment:** Muted/faded (60% opacity) for "behind the scenes" 4. **Simplicity Treatment:** Full opacity, sharp edges for customer-facing elements 5. **Connecting Elements:** Arrows between sections, consistent style ## Three Prompt Patterns ### Pattern 1: Flow Diagram (Horizontal) **Best for:** Multi-step processes with complexity reveal **Structure:** ``` VISUAL FLOW - LEFT TO RIGHT with [#] connected sections: ═══════════════════════════════════════════════════════════════ SECTION 1 - [NAME] ([Position]): [Content with specific elements] Label above: "[Section Label]" Arrow flows right → ═══════════════════════════════════════════════════════════════ SECTION 2 - [NAME] ([Position]): [Content with visual treatment notes] Arrow flows right → ═══════════════════════════════════════════════════════════════ [Continue...] ``` **Template:** `references/01-flow-pattern.md` --- ### Pattern 2: Layer Architecture (Vertical) **Best for:** System architecture, abstraction visualization **Structure:** ``` VISUAL STRUCTURE - [#] layers flowing top-to-bottom: LAYER 1 - [NAME] (Top, [treatment]): [Simple customer-facing content] Add text: "[Key message]" ↓ Flow arrow ↓ LAYER 2 - [NAME] (Middle, [treatment]): [Complex behind-the-scenes content] [Branching paths, carrier groupings] ↓ Flow arrow ↓ LAYER 3 - [NAME] (Bottom, [treatment]): [Unified output/result] Add text: "[Conclusion]" ``` **Template:** `references/02-layer-pattern.md` --- ### Pattern 3: Stage Journey (Horizontal) **Best for:** Simple customer journeys, UX flows **Structure:** ``` Visual concept: LEFT-TO-RIGHT flow with arrows connecting [#] stages: STAGE 1 - [NAME] (Left): [UI element description] [Specific content] STAGE 2 - [NAME] (Center): [UI element description] [Specific content] STAGE 3 - [NAME] (Right): [UI element description] [Specific content] MESSAGE TO CONVEY: [Conceptual contrast or key insight] ``` **Template:** `references/03-stage-pattern.md` --- ## Output Evaluation Rubric | Dimension | 1 (Weak) | 3 (Solid) | 5 (Exceptional) | |-----------|----------|-----------|-----------------| | **Concept Clarity** | Confusing flow, unclear message | Understandable with effort | Instant "aha" moment | | **Visual Hierarchy** | Flat, no emphasis | Clear sections | Key points pop in 3 seconds | | **Color Consistency** | Off-brand colors | Mostly correct palette | Perfect brand alignment | | **Treatment Contrast** | No differentiation | Some muting for complexity | Clear simple vs. complex | | **Technical Accuracy** | Errors in content | Correct but generic | Precise and nuanced | | **Production Ready** | Needs significant cleanup | Minor tweaks needed | Ready to present | **Target:** 4.0+ average for customer-facing use ## Quick Commands **Generate visual from concept:** ``` I need a [flow/layer/stage] visual explaining [TOPIC]. Key elements: - [Element 1] - [Element 2] - [Element 3] Use the Nano Banana Visual System skill to create the prompt. ``` **Evaluate generated output:** ``` Score this visual against the Nano Banana rubric. Rate each dimension 1-5 with specific observations. [paste image or describe output] ``` **Iterate on output:** ``` Refine this visual with these adjustments: 1. [Specific change] 2. [Specific change] Keep all other elements identical. ``` ## Reference Files - `references/01-flow-pattern.md` - Horizontal flow template + examples - `references/02-layer-pattern.md` - Vertical layer template + examples - `references/03-stage-pattern.md` - Stage journey template + examples - `references/04-style-guide.md` - Complete visual style specifications - `references/05-proven-prompts.md` - Battle-tested prompts that work ## Integration with Other Skills - **Brand Scout:** Generate visual one-pagers for lead reports - **CVM White Glove:** Create discovery prep visuals - **December Pipeline Priming:** Generate LinkedIn post graphics - **Practice Gym:** Evaluate generated visuals against rubric
