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 building apps with the Gemini API (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.
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-omni-flash-api Specialized generative AI video skill focused on Gemini Omni 1.1 Flash (gemini-omni-1.1-flash), video editing, image and video referenced generation, first and last frame transitions, and video extensions using the Interactions API.

Installation

You can install these skills across your preferred AI coding assistants and package managers:

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

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

Antigravity

The Gemini skills come bundled with Antigravity, find them under ⚙️ → Customizations → Build with Google Plugins.

Or install through the AGY CLI:

# Install it directly
agy plugin install https://github.com/google-gemini/gemini-skills

Claude Code

# Register the marketplace
/plugin marketplace add google-gemini/gemini-skills

# Install the plugin
/plugin install gemini-skills@gemini-skills

Cursor

Install directly from the Cursor plugin directory or via the editor command:

/add-plugin google-gemini/gemini-skills

OpenAI Codex

# Add the marketplace source
codex plugin marketplace add https://github.com/google-gemini/gemini-skills

# Install the plugin
codex plugin install gemini-skills

Gemini-skills
What is this?A collection of 'skills' (context files) for the Gemini API that teach coding agents up-to-date best practices, SDK usage, and model behaviors that are outside the model's training knowledge.
Are these skill files I install into my AI assistant, or a Python library I import into my code?They are skill files you install into AI coding assistants (like Claude Code, Cursor, or Antigravity), not a library you import into your application code.
How do I install these skills?Install via the Vercel skills CLI, Context7 skills CLI, directly inside Claude Code or Cursor, through the OpenAI Codex integration, or use them pre-bundled with Antigravity under Customizations to Build with Google Plugins.
Which coding assistants are supported?Vercel skills CLI, Context7 skills CLI, Antigravity (bundled), Claude Code, Cursor, and OpenAI Codex are all listed as supported install targets.
Do I need one skill for everything, or should I pick a specific one?There are three specialized skills: gemini-api-dev for general app building (text, chat, streaming, function calling, image generation), gemini-live-api-dev for real-time bidirectional streaming, and gemini-omni-flash-api for video generation and editing, so you pick based on what you're building.
How much does adding this skill actually help an agent?According to the authors' evaluations, adding the skill improved correct Gemini API code generation to 87% with Gemini 3 Flash and 96% with Gemini 3.1 Pro.
What happened to the vertex-ai-api-dev skill?It was moved and renamed; it now lives at skills/cloud/gemini-api in this repo.
Is this an official Google product?No, the README explicitly states it is not an officially supported Google product and is not eligible for the Google Open Source Vulnerability Rewards Program.
What does the gemini-omni-flash-api skill cover?It focuses on the Gemini Omni 1.1 Flash model for video editing, image and video referenced generation, first/last frame transitions, and video extensions via the Interactions API.
What are similar projects?generative-ai, conductor, sprite-gen, Creating-Oneshot-Hero-Landing-Pages, godogen, herk-edit-kit, cookbook, open-steps
Which topics is it in?gemini-api, function-calling, claude-skill, antigravity, codex-skill, agent-skill, google, video-generation, websocket, image-generation, streaming, skills
