Script Directory

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

Agent Execution Instructions:

Determine this SKILL.md file's directory path as SKILL_DIR Script path = ${SKILL_DIR}/scripts/.ts Replace all ${SKILL_DIR} in this document with the actual path

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:

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:

Check if consent file exists with accepted: true and disclaimerVersion: "1.0" If valid consent exists → print warning with acceptedAt date, proceed 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 Consent file format: {"version":1,"accepted":true,"acceptedAt":"","disclaimerVersion":"1.0"} Preferences (EXTEND.md)

Use Bash to check EXTEND.md existence (priority order):

Check project-level first

test -f .baoyu-skills/baoyu-danger-gemini-web/EXTEND.md && echo "project"

Then user-level (cross-platform: $HOME works on macOS/Linux/WSL)

test -f "$HOME/.baoyu-skills/baoyu-danger-gemini-web/EXTEND.md" && echo "user"
