  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:
ScriptPurpose

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"}

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.
