| description | Browser-automated file download with enhanced features. Auto-detects platform (Windows/macOS/Linux, 64/32-bit, ARM/Intel), handles multi-step navigation (homepage to platform-specific pages), captures auto-downloads triggered on page load, and falls back to button clicking when needed. Ideal for complex download flows where curl/wget fail due to client-side rendering, automatic downloads, or multi-page navigation. Features page scrolling for lazy content, extended wait times, and Golang support. Use when this capability is needed. |

Browser Auto Download v4.1.0 (Enhanced)
Download files from dynamic webpages with intelligent detection and multi-step navigation.
Key Features
- Auto-download capture: Detects downloads triggered automatically on page load
- Multi-step navigation: Finds and navigates to platform-specific pages (PC/Desktop versions)
- Platform auto-detection: Windows x64/ARM64, macOS Intel/Apple Silicon, Linux
- Event listening: Captures all download events without requiring button clicks
- Smart fallback: Tries multiple strategies (auto-download, navigation, clicking)
When to Use
Use this skill for:
- Auto-download sites: Downloads start automatically when page loads
- Multi-step flows: Homepage - click "PC version" - download page
- Dynamic content: Download links generated via JavaScript
- Interactive downloads: Requires clicking buttons or navigating UI
NOT for: Direct file URLs (use curl/wget instead)
Quick Start
Option 1: Automatic (Recommended)
python skills/browser-auto-download/scripts/auto_download.py \
--url "https://example.com/download"
The script will:
- Check for auto-downloads on page load
- Look for platform-specific page links (PC/Desktop version)
- Navigate if needed
- Try clicking download buttons as fallback
Option 2: Built-in Shortcuts
python skills/browser-auto-download/scripts/auto_download.py --wechat
python skills/browser-auto-download/scripts/auto_download.py --meitu
Option 3: Python Module
from skills.browser-auto-download.scripts.auto_download import auto_download
result = auto_download(
url="https://example.com/download",
auto_select=True,
auto_navigate=True
)
if result:
print(f"Downloaded: {result['path']}")
How It Works
Three-Stage Strategy
Stage 1: Auto-Download Detection
Page loads - Check for downloads - Success?
Yes: No:
Save file Go to Stage 2
Stage 2: Multi-Step Navigation
Look for "PC/Desktop" link - Navigate - Check downloads - Success?
Yes: No:
Save file Go to Stage 3
Stage 3: Button Clicking
Try multiple selectors - Click - Wait for download - Save
Platform-Specific Page Detection
Automatically finds links like:
- "meitu for PC" - pc.meitu.com
- "Desktop version" - desktop.example.com
- "Windows Download" - windows.example.com
Keywords: pc, desktop, windows, mac, download, 电脑, 桌面, 客户端
Examples
Auto-Download Sites (Best Case)
python skills/browser-auto-download/scripts/auto_download.py \
--url "https://pc.meitu.com/en/pc?download=pc"
Multi-Step Navigation
python skills/browser-auto-download/scripts/auto_download.py \
--url "https://xiuxiu.meitu.com/" \
--auto-navigate
Manual Selector (Fallback)
python skills/browser-auto-download/scripts/auto_download.py \
--url "https://example.com/download" \
--selector "button:has-text('Download for free')"
Disable Features
python skills/browser-auto-download/scripts/auto_download.py \
--url "https://example.com" \
--no-auto-navigate
python skills/browser-auto-download/scripts/auto_download.py \
--url "https://example.com" \
--no-auto-select
Platform Detection
| System | Architecture | Keywords Used |

| Windows | AMD64/x86_64 | windows, win64, x64, 64-bit, pc |
| Windows | x86/i686 | windows, win32, x86, 32-bit, pc |
| macOS | ARM64 (M1/M2/M3) | macos, arm64, apple silicon |
| macOS | x86_64 (Intel) | macos, x64, intel |
| Linux | x86_64 | linux, x64, amd64 |
Troubleshooting
Download not starting:
- Use
--headless (default: False) to observe the process
- Check stderr for auto-download messages
- Try
--no-auto-navigate if navigation is causing issues
- Use
--selector to manually specify button
Wrong version downloaded:
- Check platform detection in stderr output
- Use
--no-auto-select and manually specify --selector
- Verify the site offers multiple versions
Navigation going to wrong page:
- Disable with
--no-auto-navigate
- The site may not have platform-specific pages
File not saved:
- Check write permissions in output directory
- Ensure sufficient disk space
- Wait for large files (up to 3 minutes)
