Gemini Web Client

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

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.

AskUserQuestion

Script Directory

Important: All scripts are located in the

scripts/

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:

scripts/main.ts

scripts/gemini-webapi/*

gemini_webapi

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 in priority order — the first one found wins:

.baoyu-skills/baoyu-danger-gemini-web/EXTEND.md

${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-danger-gemini-web/EXTEND.md

$HOME/.baoyu-skills/baoyu-danger-gemini-web/EXTEND.md

If none found, use defaults.

EXTEND.md supports: Default model, proxy settings, custom data directory.
