Using Gemini Gems

Gems are not Claude Code skills. They’re Gemini Gems — persistent system prompts you paste into Gemini to turn it into a specific assistant persona. This hub hosts the prompts so you can copy them into your own Gemini workspace.

The difference from skills

	Skills	Gems
Agent	Claude Code	Gemini
Install	gh skill install ...	Paste prompt into Gemini Gem
Lives in	.claude/skills/	Your Gemini account
Can read project files	Yes (with allowed-tools frontmatter)	No — whatever Gemini’s integrations provide
Invocation	/skill-name or natural language	Open the Gem in Gemini chat

How to use a gem

1. Open Gemini Gems. Go to gemini.google.com/gems and click “Create Gem”.

2. Copy the prompt. Each gem’s page has a “Source” link to the raw prompt on GitHub. Copy the full content.

3. Paste into the Gem’s instructions. In the Gem creation UI, paste the prompt into the instructions field. Give the Gem a name (e.g., “Daily Briefing”) and optional description.

4. Authorize integrations if needed. Gems like daily-briefing need access to Gemini’s Google Calendar and Gmail connectors — grant the permissions on first use.

5. Save and use. The Gem now shows up in your Gemini sidebar. Open it, type the activation phrase (e.g., start for daily-briefing), and the assistant runs the persona.

Hardcoded dates and examples

Some gems (notably daily-briefing) have example dates or placeholders in the prompt. Read the prompt before pasting and replace any hardcoded values with what you actually want.

The three gems

daily-briefing Morning briefing pulling Google Calendar + Gmail into two clean sections.

jp-communication-enhancer English drafts → three levels of business Japanese with explanations.

thumbnail-generator Tech article titles → 2–3 high-CTR thumbnails, no third-party logos.

Why gems at all?

Skills do a lot, but they can’t run image generation, can’t hit Google’s Calendar/Gmail APIs without setup, and don’t live inside Gemini’s Workspace integration. For those three use cases, Gemini Gems are the right tool — so the prompts live here alongside skills instead of in a separate place.
