What it does

Once installed, the agent can send prompts to Google's Gemini chat service and get back text or generated images, including images based on reference pictures and multi-turn chats that remember earlier messages. It does this by calling an unofficial, reverse-engineered version of the Gemini web API through a TypeScript script run with Bun or npx, rather than through Google's official developer API. Authentication relies on cookies from your signed-in browser session, which the script can refresh by opening or reusing a local Chrome/Chromium session.

Great for

  • Developers who want an agent to create images or text with Gemini without buying API access
  • Creators who want image generation as a backend for other skills
  • Users who already have a Google account signed in to Gemini in their browser

Skip it if

  • Production or commercial systems that need stable, supported access, because the API is unofficial and can break or be blocked without notice
  • Anyone uncomfortable with a script reusing their Google login cookies or driving their browser session, since this carries account risk and may violate Google's terms

Try asking

  • “Generate an image of a cute cat and save it as cat.png using Gemini”
  • “Describe this reference image using Gemini vision”
  • “Create a variation of reference.png and save the result as out.png”
  • “Continue a multi-turn Gemini conversation under session abc”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Set --profile-dir or GEMINI_WEB_CHROME_PROFILE_DIR to use a dedicated browser profile instead of reusing your everyday Chrome session
  • Review the consent disclaimer carefully on first use, since the skill requires explicit acceptance of reverse-engineered API usage
  • Use --login to refresh cookies when requests start failing, and keep the cookie file private
