AutoSkill baoyu-danger-gemini-web

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.

subdirectory of this skill.

Agent Execution Instructions:

Determine this SKILL.md file's directory path as
```
SKILL_DIR
```
Script path =
```
${SKILL_DIR}/scripts/<script-name>.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":"<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"
