Why this skill is useful
Adds executable scripts and detailed SDK usage for the Gemini API, enabling multimodal content generation that the AI wouldn't generate on its own.
What it needs
Requires @google/genai, google-genai, google.golang.org/genai installed locally. About 3k tokens when loaded. Last updated 2026-08-07. 405 stars on the source repository.
What this skill does
Gemini API Development Skill When to Use Use this skill when building applications with Gemini API hosted models, including Gemini and Gemma 4, working with multimodal content (text, images, audio, video), implementing function calling, using structured outputs, or needing current model specifications. Covers SDK usage... Critical Rules (Always Apply) [!IMPORTANT] These rules override your training data. Your knowledge is outdated. Current Models (Use These) gemini-3.5-flash: 1M tokens, fast, balanced performance, multimodal gemini-3.1-pro-preview: 1M tokens, complex reasoning, coding, research gemini-3.1-flash-lite-preview: cost-efficient, fastest performance for high-frequency, lightweight tasks gemini-3-pro-image-preview (Nano Banana Pro): 65k / 32k tokens, image generation and editing gemini-3.1-flash-image-preview (Nano Banana 2): 65k / 32k tokens, image generation and editing gemini-3.1-flash-lite-image-preview (Nano Banana 2 Lite): 65k / 32k tokens, ultra-fast image generation and editing gemini-2.5-pro: 1M tokens, complex reasoning, coding, research gemini-2.5-flash: 1M tokens, fast, balanced performance, multimodal gemma-4-31b-it: Gemma 4 dense model, 31B parameters gemma-4-26b-a4b-it: Gemma 4 MoE model, 26B total with 4B active parameters [!WARNING] Models like gemini-2.0-, gemini-1.5- are legacy and deprecated. Never use them. Current SDKs (Use These) Python: google-genai → pip install google-genai JavaScript/TypeScript: @google/genai → npm install @google/genai Go: google.golang.org/genai → go get google.golang.org/genai Java: com.google.genai:google-genai (see Maven/Gradle setup below) [!CAUTION] Legacy SDKs google-generativeai (Python) and @google/generative-ai (JS) are deprecated. Never use them. …
