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-devskill 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, speech generation (TTS), Voice Design, Voice Replication, managed agents, Deep Research, deprecated model guardrails, and both Python and TypeScript SDKs. |
gemini-api-cli | Skill for calling the Gemini API from the shell with gemini-api. Covers text and media generation (image, tts, music, video), file and YouTube analysis, transcription, Deep Research, Antigravity sandboxes, and --jq / --body scripting. |
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 1.2 Flash (gemini-omni-1.2-flash), video editing, image and video referenced generation, first and last frame transitions, and video extensions (3s–15s per turn, up to 40s total) using the Interactions API. |

@mattpocockecc
Gives your coding agent a planning, testing and review routine to follow on every task. It plans before building, checks changes with tests, has a fresh reviewer look for regressions, and saves repeated wins as reusable skills.

@facebookQuestions about gemini-skills.
Install it with the command on its page. It includes gemini-api-cli, gemini-api-dev, gemini-live-api-dev. Its skills do not fire on their own yet. Free and open source.
- What is gemini-skills?
- google-gemini/gemini-skills is a plugin of skills for the Gemini API, SDK and model interactions. It covers text, chat, multimodal and video generation, plus real-time streaming through the Live API, so it suits developers writing code that calls Gemini.
- How do I install gemini-skills?
- Run these in Claude Code: /plugin marketplace add google-gemini/gemini-skills then /plugin install gemini-skills@gemini-skills. Then prompt normally.
- Does gemini-skills auto-invoke its skills?
- Not yet. It is indexed on Flowy as a plain plugin.
- Is gemini-skills free?
- Yes. Flowy is free and open source, with nothing gated. You can read every skill in full before you install.
- Which coding agents can use gemini-skills's skills?
- gemini-skills installs in Claude Code, and its skills also install in Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and Windsurf with the skills CLI. Each skill's page has the install command. Flowy's auto-invocation, which fires a skill when your prompt matches, runs in Claude Code only.
