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/<script-name>.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 :

Consent Check (REQUIRED)

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

Consent file locations :

• 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

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

Preferences (EXTEND.md)

Check EXTEND.md existence (priority order):

# macOS, Linux, WSL, Git Bash
test -f .baoyu-skills/baoyu-danger-gemini-web/EXTEND.md && echo "project"
test -f "${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-danger-gemini-web/EXTEND.md" && echo "xdg"
test -f "$HOME/.baoyu-skills/baoyu-danger-gemini-web/EXTEND.md" && echo "user"



# PowerShell (Windows)
if (Test-Path .baoyu-skills/baoyu-danger-gemini-web/EXTEND.md) { "project" }
$xdg = if ($env:XDG_CONFIG_HOME) { $env:XDG_CONFIG_HOME } else { "$HOME/.config" }
if (Test-Path "$xdg/baoyu-skills/baoyu-danger-gemini-web/EXTEND.md") { "xdg" }
if (Test-Path "$HOME/.baoyu-skills/baoyu-danger-gemini-web/EXTEND.md") { "user" }

Options

Models

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

Sessions

Session files stored in data directory under sessions/<id>.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.
