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:

    ScriptPurpose
    scripts/main.tsCLI 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"
