Gemini API skills

A library of skills for the Gemini API, SDK and model interactions.

About

LLMs have fixed knowledge, being trained at a specific point in time. Software dev is fast paced and changes often, where new libraries are launched every day and best practices evolve quickly.

This leaves a knowledge gap that language models can't solve on their own. For example, models don't know about themselves when they're trained, and they aren't necessarily aware of subtle changes in best practices (like thought circulation) or SDK changes.

Skills are a lightweight technique for adding relevant context to your agents. This repo contains skills related to building apps powered by the Gemini API.

Performance

Our evaluations found that adding this skill improved an agent's ability to generate correct API code following best practices to 87% with Gemini 3 Flash and 96% with Gemini 3.1 Pro. For more details, see our blog post: Closing the knowledge gap with agent skills.

Skills in this repo

[!IMPORTANT] The vertex-ai-api-dev skill has moved to skills/cloud/gemini-api.

Skill	Description
gemini-api-dev	Skill for developing Gemini-powered apps. Provides the best practices for building apps that use the Gemini API.
gemini-live-api-dev	Skill for building real-time, bidirectional streaming apps with the Gemini Live API. Covers WebSocket-based audio/video/text streaming, voice activity detection, native audio features, function calling, and session management.
gemini-interactions-api	Skill for building apps with the Gemini Interactions API. Covers text generation, multi-turn chat, streaming, function calling, structured output, image generation, Deep Research agents, deprecated model guardrails, and both Python and TypeScript SDKs.

Installation

You can browse and install skills using either the Vercel skills CLI or the Context7 skills CLI.

Using Vercel skills CLI

# Interactively browse and install skills.
npx skills add google-gemini/gemini-skills --list

# Install a specific skill (e.g., gemini-api-dev).
npx skills add google-gemini/gemini-skills --skill gemini-api-dev --global

Using Context7 skills CLI

# Interactively browse and install skills.
npx ctx7 skills install /google-gemini/gemini-skills

# Install a specific skill (e.g., gemini-api-dev).
npx ctx7 skills install /google-gemini/gemini-skills gemini-api-dev

Gemini API docs MCP

A public Model Context Protocol (MCP) server for the Gemini API is available at https://gemini-api-docs-mcp.dev. Connecting your coding agent to this server ensures that all queries have access to the latest APIs, code updates, and optimal configuration examples.

Run the following command in your agent's terminal or project root to install the server:

npx add-mcp "https://gemini-api-docs-mcp.dev"

This server adds a search_docs tool that your agent can use to retrieve real-time API definitions and integration patterns from the official Gemini API documentation.

Note that the gemini-api-dev skill works with or without the MCP server, so we recommend installing them both.

You can find additional information about setting up your coding assistant with Gemini API MCP and Skills in the docs.
