name: baoyu-danger-gemini-web
description: Generates images and text via reverse-engineered Gemini Web API. Supports text generation, image generation from prompts, reference images for vision input, and multi-turn conversations. Use when other skills need image generation backend, or when user requests "generate image with Gemini", "Gemini text generation", or needs vision-capable AI generation.

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 SKILL_DIR
2. Script path = ${SKILL_DIR}/scripts/<script-name>.ts
3. 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:
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)

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"
