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/thought-signatures)) 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.
