EXTEND.md Supports: Default output directory | Default capture mode | Timeout settings

Features

Chrome CDP for full JavaScript rendering
Two capture modes: auto or wait-for-user
Clean markdown output with metadata
Handles login-required pages via wait mode

Usage

bash

# Auto mode (default) - capture when page loads
npx -y bun ${SKILL_DIR}/scripts/main.ts <url>

# Wait mode - wait for user signal before capture
npx -y bun ${SKILL_DIR}/scripts/main.ts <url> --wait

# Save to specific file
npx -y bun ${SKILL_DIR}/scripts/main.ts <url> -o output.md

Options

Option	Description
`<url>`	URL to fetch
`-o <path>`	Output file path (default: auto-generated)
`--wait`	Wait for user signal before capturing
`--timeout <ms>`	Page load timeout (default: 30000)

Capture Modes

Mode	Behavior	Use When
Auto (default)	Capture on network idle	Public pages, static content
Wait ( `--wait` )	User signals when ready	Login-required, lazy loading, paywalls

Wait mode workflow:

Run with

→ script outputs "Press Enter when ready"
Ask user to confirm page is ready
Send newline to stdin to trigger capture
