What this skill does
🍌 Nano-Banana Expert Skill (Gemini 3 Style) A specialized skill for AI Agents to leverage "Reasoning-Driven" image generation. Based on the advanced prompting architecture of Google's Gemini 3 (Nano Banana Pro), this skill moves beyond keyword stuffing to structured, logic-based creative briefs. Core Competencies 1. Reasoning-Driven Prompting: Using natural language logic to define physics, lighting, and spatial relationships. 2. Structured Creative Briefs: Implementing the "Perfect Prompt" formula: Subject + Action + Context + Composition + Lighting. 3. Text Rendering Precision: Explicitly defining typography and signifiers for legible text integration. 4. Contextual Grounding: Using "Search Grounding" logic (simulated) to anchor generations in real-world accuracy. --- 🏗️ Technical Specification 1. The "Perfect Prompt" Formula Component Description Example :--- :--- :--- Subject Detailed entity description "A stoic robot barista with exposed copper wiring" Action Dynamic interaction "Pouring a latte art leaf with mechanical precision" Context Environment & Atmosphere "Inside a neon-lit cyberpunk cafe at midnight" Composition Camera & Lens choice "Close-up, 85mm lens, f/1.8 aperture" Lighting Mood & Direction "Volumetric blue rim light, warm cafe glow" Style Aesthetic anchor "Cinematic, photorealistic, 4K production value" 2. Advanced Features Negative Constraint Logic: Instead of "no blurry," use "Ensure sharp focus on the subject's eyes." Identity Consistency: (Simulated) "Maintain consistent facial structure across variations." Text Integration: Use double quotes for specific text: The sign reads "OPEN 24/7". --- 🧠 Prompt Optimization Protocol (Agent Instruction) Before calling the script, the Agent MUST rewrite the user's prompt into a logic-driven Reasoning Brief: 1. NO KEYWORD SOUP: Remove "8k, masterpiece, ultra-detailed." Use full, descriptive sentences. 2. …
