Baoyu Danger Gemini Web

Gemini Web Client

Text/image generation via Gemini Web API. Supports reference images and multi-turn conversations.

Script Directory

Important: All scripts are located in the scripts/ subdirectory of this skill.

Agent Execution Instructions: 1. Determine this SKILL.md file's directory path as {baseDir} 2. Script path = {baseDir}/scripts/.ts 3. Resolve ${BUN_X} runtime: if bun installed → bun; if npx available → npx -y bun; else suggest installing bun 4. Replace all {baseDir} and ${BUN_X} in this document with actual values

Script Reference: | Script | Purpose | |--------|---------| | scripts/main.ts | CLI entry point for text/image generation | | scripts/gemini-webapi/* | TypeScript port of gemini_webapi (GeminiClient, types, utils) |

Consent Check (REQUIRED)

Before first use, verify user consent for reverse-engineered API usage.

Consent file locations:

Flow: 1. Check if consent file exists with accepted: true and disclaimerVersion: "1.0" 2. If valid consent exists → print warning with acceptedAt date, proceed 3. If no consent → show disclaimer, ask user via AskUserQuestion: - "Yes, I accept" → create consent file with ISO timestamp, proceed - "No, I decline" → output decline message, stop 4. Consent file format: {"version":1,"accepted":true,"acceptedAt":"","disclaimerVersion":"1.0"}

Preferences (EXTEND.md)

Usage

# Text generation
${BUN_X} {baseDir}/scripts/main.ts "Your prompt"
${BUN_X} {baseDir}/scripts/main.ts --prompt "Your prompt" --model gemini-3-flash
Image generation
${BUN_X} {baseDir}/scripts/main.ts --prompt "A cute cat" --image cat.png
${BUN_X} {baseDir}/scripts/main.ts --promptfiles system.md content.md --image out.png
Vision input (reference images)
${BUN_X} {baseDir}/scripts/main.ts --prompt "Describe this" --reference image.png
${BUN_X} {baseDir}/scripts/main.ts --prompt "Create variation" --reference a.png --image out.png
Multi-turn conversation
${BUN_X} {baseDir}/scripts/main.ts "Remember: 42" --sessionId session-abc
${BUN_X} {baseDir}/scripts/main.ts "What number?" --sessionId session-abc
JSON output
${BUN_X} {baseDir}/scripts/main.ts "Hello" --json

Options

| Option | Description | |--------|-------------| | --prompt, -p | Prompt text | | --promptfiles | Read prompt from files (concatenated) | | --model, -m | Model: gemini-3-pro (default), gemini-3-flash, gemini-3-flash-thinking, gemini-3.1-pro-preview | | --image [path] | Generate image (default: generated.png) | | --reference, --ref | Reference images for vision input | | --sessionId | Session ID for multi-turn conversation | | --list-sessions | List saved sessions | | --json | Output as JSON | | --login | Refresh cookies, then exit | | --cookie-path | Custom cookie file path | | --profile-dir | Chrome profile directory |

Models

| Model | Description | |-------|-------------| | gemini-3-pro | Default, latest 3.0 Pro | | gemini-3-flash | Fast, lightweight 3.0 Flash | | gemini-3-flash-thinking | 3.0 Flash with thinking | | gemini-3.1-pro-preview | 3.1 Pro preview (empty header, auto-routed) |

Authentication

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.

Environment Variables

| 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) |

Sessions

Session files stored in data directory under sessions/.json.

Contains: id, metadata (Gemini chat state), messages array, timestamps.

Extension Support

Custom configurations via EXTEND.md. See Preferences section for paths and supported options.
