Agent Execution Instructions:

1. Determine this SKILL.md file's directory path as SKILL_DIR
2. Script path = ${SKILL_DIR}/scripts/.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) |

Before using this skill, the consent check MUST be performed.

Consent Check Flow

Step 1: Check consent file

```bash

# macOS

cat ~/Library/Application\ Support/baoyu-skills/gemini-web/consent.json 2>/dev/null

# Linux

cat ~/.local/share/baoyu-skills/gemini-web/consent.json 2>/dev/null

# Windows (PowerShell)

Get-Content "$env:APPDATA\baoyu-skills\gemini-web\consent.json" 2>$null

```

Step 2: If consent exists and accepted: true with matching disclaimerVersion: "1.0":

Print warning and proceed:

```

⚠️ Warning: Using reverse-engineered Gemini Web API (not official). Accepted on:

```

Step 3: If consent file doesn't exist or disclaimerVersion mismatch:

Display disclaimer and ask user:

```

⚠️ DISCLAIMER

This tool uses a reverse-engineered Gemini Web API, NOT an official Google API.

Risks:

• May break without notice if Google changes their API
• No official support or guarantees
• Use at your own risk

Do you accept these terms and wish to continue?

```

Use AskUserQuestion tool with options:

• Yes, I accept - Continue and save consent
• No, I decline - Exit immediately

Step 4: On acceptance, create consent file:

```bash

# macOS

mkdir -p ~/Library/Application\ Support/baoyu-skills/gemini-web

cat > ~/Library/Application\ Support/baoyu-skills/gemini-web/consent.json << 'EOF'

{

"version": 1,

"accepted": true,

"acceptedAt": "",

"disclaimerVersion": "1.0"

}

EOF

# Linux

mkdir -p ~/.local/share/baoyu-skills/gemini-web

cat > ~/.local/share/baoyu-skills/gemini-web/consent.json << 'EOF'

{

"version": 1,

"accepted": true,

"acceptedAt": "",

"disclaimerVersion": "1.0"

}

EOF

```

Step 5: On decline, output message and stop:

```

User declined the disclaimer. Exiting.

```

```bash

npx -y bun ${SKILL_DIR}/scripts/main.ts "Hello, Gemini"

npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "Explain quantum computing"

npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "A cute cat" --image cat.png

npx -y bun ${SKILL_DIR}/scripts/main.ts --promptfiles system.md content.md --image out.png

# Multi-turn conversation (agent generates unique sessionId)

npx -y bun ${SKILL_DIR}/scripts/main.ts "Remember this: 42" --sessionId my-unique-id-123

npx -y bun ${SKILL_DIR}/scripts/main.ts "What number?" --sessionId my-unique-id-123

```

Text generation

```bash

# Simple prompt (positional)

npx -y bun ${SKILL_DIR}/scripts/main.ts "Your prompt here"

# Explicit prompt flag

npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "Your prompt here"

npx -y bun ${SKILL_DIR}/scripts/main.ts -p "Your prompt here"

# With model selection

npx -y bun ${SKILL_DIR}/scripts/main.ts -p "Hello" -m gemini-2.5-pro

# Pipe from stdin

echo "Summarize this" | npx -y bun ${SKILL_DIR}/scripts/main.ts

```

Image generation

```bash

# Generate image with default path (./generated.png)

npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "A sunset over mountains" --image

# Generate image with custom path

npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "A cute robot" --image robot.png

# Shorthand

npx -y bun ${SKILL_DIR}/scripts/main.ts "A dragon" --image=dragon.png

```

Vision input (reference images)

```bash

# Text + image -> text

npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "Describe this image" --reference a.png

# Text + image -> image

npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "Generate a variation" --reference a.png --image out.png

```

Output formats

```bash

# Plain text (default)

npx -y bun ${SKILL_DIR}/scripts/main.ts "Hello"

# JSON output

npx -y bun ${SKILL_DIR}/scripts/main.ts "Hello" --json

```

| Option | Description |

|--------|-------------|

| --prompt , -p | Prompt text |

| --promptfiles | Read prompt from files (concatenated in order) |

| --model , -m | Model: gemini-3-pro (default), gemini-2.5-pro, gemini-2.5-flash |

| --image [path] | Generate image, save to path (default: generated.png) |

| --reference , --ref | Reference images for vision input |

| --sessionId | Session ID for multi-turn conversation (agent generates unique ID) |

| --list-sessions | List saved sessions (max 100, sorted by update time) |

| --json | Output as JSON |

| --login | Refresh cookies only, then exit |

| --cookie-path | Custom cookie file path |

CLI note: scripts/main.ts supports text generation, image generation, reference images (--reference/--ref), and multi-turn conversations via --sessionId.

• gemini-3-pro - Default, latest model
• gemini-2.5-pro - Previous generation pro
• gemini-2.5-flash - Fast, lightweight

First run opens a browser to authenticate with Google. Cookies are cached for subsequent runs.

Supported browsers (auto-detected in order):

• Google Chrome
• Google Chrome Canary / Beta
• Chromium
• Microsoft Edge

Override with GEMINI_WEB_CHROME_PATH environment variable if needed.

```bash

# Force cookie refresh

npx -y bun ${SKILL_DIR}/scripts/main.ts --login

```

| Variable | Description |

|----------|-------------|

| GEMINI_WEB_DATA_DIR | Data directory |

| GEMINI_WEB_COOKIE_PATH | Cookie file path |

| GEMINI_WEB_CHROME_PROFILE_DIR | Chrome profile directory |

| GEMINI_WEB_CHROME_PATH | Chrome executable path |

If you need a proxy to access Google services (e.g., in China), set HTTP_PROXY and HTTPS_PROXY environment variables before running:

```bash

# Example with local proxy

HTTP_PROXY=http://127.0.0.1:7890 HTTPS_PROXY=http://127.0.0.1:7890 npx -y bun ${SKILL_DIR}/scripts/main.ts "Hello"

# Image generation with proxy

HTTP_PROXY=http://127.0.0.1:7890 HTTPS_PROXY=http://127.0.0.1:7890 npx -y bun ${SKILL_DIR}/scripts/main.ts --prompt "A cat" --image cat.png

# Cookie refresh with proxy

HTTP_PROXY=http://127.0.0.1:7890 HTTPS_PROXY=http://127.0.0.1:7890 npx -y bun ${SKILL_DIR}/scripts/main.ts --login

```

Note: Environment variables must be set inline with the command. Shell profile settings (e.g., .bashrc) may not be inherited by subprocesses.

Generate text response

```bash

npx -y bun ${SKILL_DIR}/scripts/main.ts "What is the capital of France?"

```

Generate image

```bash

npx -y bun ${SKILL_DIR}/scripts/main.ts "A photorealistic image of a golden retriever puppy" --image puppy.png

```

Get JSON output for parsing

```bash

npx -y bun ${SKILL_DIR}/scripts/main.ts "Hello" --json | jq '.text'

```

Generate image from prompt files

```bash

# Concatenate system.md + content.md as prompt

npx -y bun ${SKILL_DIR}/scripts/main.ts --promptfiles system.md content.md --image output.png

```

Multi-turn conversation

```bash

# Start a session with unique ID (agent generates this)

npx -y bun ${SKILL_DIR}/scripts/main.ts "You are a helpful math tutor." --sessionId task-abc123

# Continue the conversation (remembers context)

npx -y bun ${SKILL_DIR}/scripts/main.ts "What is 2+2?" --sessionId task-abc123

npx -y bun ${SKILL_DIR}/scripts/main.ts "Now multiply that by 10" --sessionId task-abc123

# List recent sessions (max 100, sorted by update time)

npx -y bun ${SKILL_DIR}/scripts/main.ts --list-sessions

```

Session files are stored in ~/Library/Application Support/baoyu-skills/gemini-web/sessions/.json and contain:

• id: Session ID
• metadata: Gemini chat metadata for continuation
• messages: Array of {role, content, timestamp, error?}
• createdAt, updatedAt: Timestamps

Custom configurations via EXTEND.md.

Check paths (priority order):

1. .baoyu-skills/baoyu-danger-gemini-web/EXTEND.md (project)
2. ~/.baoyu-skills/baoyu-danger-gemini-web/EXTEND.md (user)

If found, load before workflow. Extension content overrides defaults.
