Is the Gemini Image Generator skill free?

Yes. The skill itself is free from mkdev-me/agent-skills. SkillProof publishes the install command and an independent test verdict at no cost.

How do I install Gemini Image Generator?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Gemini Image Generator with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Didn't pass
Tested: Jul 30, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · 4c2b334

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 30, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

The 111-line script is honest about what it does — build the request, save the returned image, no telemetry — and it wires up correctly: after the documented venv setup it reached generativelanguage.googleapis.com and came back with a real 400 API_KEY_INVALID, so the plumbing is sound but the actual image is unverifiable without a paid Google AI Studio key. Two rough edges cost it points. Run it with no key and it tells you to `export GOOGLE_API_KEY`, while the code only ever reads GEMINI_API_KEY, so a first-time user follows the error message into a dead end. The README's own install snippet clones a repo name that no longer matches and omits `mkdir -p ~/.claude/skills`, which we confirmed installs nothing at all on a fresh machine.

What Gemini Image Generator does

A small Python CLI that calls Google's gemini-3-pro-image-preview model to generate an image from a text prompt, optionally guided by one or more reference images, at 1K, 2K or 4K and saved to a path you choose. Triggers when you ask Claude to generate, create or edit an image file rather than describe one. Needs a Google AI Studio API key and a one-time virtualenv setup.

How to install Gemini Image Generator

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.

Commands — how to trigger Gemini Image Generator

/gemini-image-generator Generates images with Google Gemini from a prompt or a reference image

It also activates on plain-language prompts like these:

Generate a 4K image of a mountain landscape at sunset using Gemini
Create a product shot guided by this reference photo with Gemini's model
Make a PNG illustration for my blog header at 2K and save it to assets/
