Generates images and text via reverse-engineered Gemini Web API. Supports text generation, image generation from prompts, reference images for vision input, and multi-turn conversations. Use when other skills need image generation backend, or when user requests "generate image with Gemini", "Gemini text generation", or needs vision-capable AI generation.

First run opens browser for Google auth. Cookies cached automatically.
When no explicit profile dir is set, cookie refresh may reuse an already-running local Chrome/Chromium debugging session tied to a standard user-data dir.
Set --profile-dir or GEMINI_WEB_CHROME_PROFILE_DIR to force a dedicated profile and skip existing-session reuse.
This is a best-effort CDP session reuse path, not the Chrome DevTools MCP prompt-based --autoConnect flow described in Chrome's official docs.
Supported browsers (auto-detected): Chrome, Chrome Canary/Beta, Chromium, Edge.
Force refresh: --login flag. Override browser: GEMINI_WEB_CHROME_PATH env var.
| Variable | Description |
|---|---|
GEMINI_WEB_DATA_DIR | Data directory |
GEMINI_WEB_COOKIE_PATH | Cookie file path |
GEMINI_WEB_CHROME_PROFILE_DIR | Chrome profile directory |
GEMINI_WEB_CHROME_PATH | Chrome executable path |
HTTP_PROXY, HTTPS_PROXY | Proxy for Google access (set inline with command) |
Session files stored in data directory under sessions/<id>.json.
Contains: id, metadata (Gemini chat state), messages array, timestamps.
