Baoyu Danger Gemini Web skill

Gemini Web Client

User Input Tools

When this skill prompts the user, follow this tool-selection rule (priority order):

1. Prefer built-in user-input tools exposed by the current agent runtime — e.g., AskUserQuestion, request_user_input, clarify, ask_user, or any equivalent.
2. Fallback: if no such tool exists, emit a numbered plain-text message and ask the user to reply with the chosen number/answer for each question.
3. Batching: if the tool supports multiple questions per call, combine all applicable questions into a single call; if only single-question, ask them one at a time in priority order.

Concrete AskUserQuestion references below are examples — substitute the local equivalent in other runtimes.

Script Directory

{baseDir} = this SKILL.md's directory; scripts are at {baseDir}/scripts/<script-name>.ts. Resolve ${BUN_X}: bun if installed; else npx -y bun; else suggest installing bun. Replace {baseDir} and ${BUN_X} with actual values.

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:

• macOS: ~/Library/Application Support/baoyu-skills/gemini-web/consent.json
• Linux: ~/.local/share/baoyu-skills/gemini-web/consent.json
• Windows: %APPDATA%\baoyu-skills\gemini-web\consent.json

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":"<ISO>","disclaimerVersion":"1.0"}

Authentication

First run opens a browser for Google auth; cookies are cached. Force refresh: --login. Override browser: GEMINI_WEB_CHROME_PATH. Auto-detected browsers: Chrome, Chrome Canary/Beta, Chromium, Edge.

Without an explicit profile dir, cookie refresh may reuse an already-running local Chrome/Chromium debugging session tied to a standard user-data dir (best-effort CDP reuse, not Chrome DevTools MCP's --autoConnect flow). Set --profile-dir or GEMINI_WEB_CHROME_PROFILE_DIR to force a dedicated profile and skip that reuse.

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 (bash: set inline with command; PowerShell: $env:HTTPS_PROXY = '...' before running)

Sessions

Stored in the data directory as sessions/<id>.json, containing id, metadata (Gemini chat state), messages array, timestamps.

Extension Support

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