Authentication

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.

# Force cookie refresh
npx -y bun ${SKILL_DIR}/scripts/main.ts --login

Environment variables

Proxy Configuration

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

# 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.

Examples

Generate text response

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

Generate image

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

Get JSON output for parsing

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

Generate image from prompt files

# 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

# 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/<id>.json and contain:

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

Extension Support

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.
