Gemini Skills

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](https://ai.google.dev/gemini-api/docs/thinking#signatures)) or SDK changes.

[Skills](https://agentskills.io/) 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 Pro.
