DuckDuckGo Web Search Skill

An Agent Skill for searching web content via DuckDuckGo.

Overview

This Skill provides a command-line tool for web search using the ddgs Python package. Suitable for:

• Real-time web information needs in AI coding tools
• Fetching search results in OpenClaw workflows

Core Features

• Web Search: General web search
• News Search: Dedicated news content search
• Multiple Output Formats: Text or JSON format
• Flexible Configuration: Region, time limits, and safe search level
• Proxy Support: HTTP/HTTPS/SOCKS5 proxy via CLI args or environment variables

Installation

This project uses uv as the Python package manager.

Option 1: Run with uv (Recommended)

# Run the script directly (uv will auto-install dependencies)
uv run scripts/ddgs_search.py "Python programming"

# Or navigate to the directory first
cd skills/ddgs-search
uv run scripts/ddgs_search.py "machine learning"

Option 2: Manual Dependency Installation

# Install dependencies using uv
uv pip install ddgs

# Or use pip
pip install ddgs

Quick Start

Basic Usage

# Run with uv (recommended)
uv run scripts/ddgs_search.py "Python programming"

# Limit the number of results
uv run scripts/ddgs_search.py "machine learning" --max-results 5

# Search news
uv run scripts/ddgs_search.py "tech news" --news

# JSON output (for programmatic parsing)
uv run scripts/ddgs_search.py "API documentation" --json

# Time limit (today)
uv run scripts/ddgs_search.py "breaking news" --timelimit d

Usage in OpenClaw

In OpenClaw workflows, you can invoke it via the bash tool:

# Example workflow step
- name: search_web
  tool: bash
  command: cd skills/ddgs-search && uv run scripts/ddgs_search.py "{{ query }}" --json

Or using the Python tool:

# Assuming the current directory is the project root
import subprocess
import json

result = subprocess.run(
    ["uv", "run", "skills/ddgs-search/scripts/ddgs_search.py", "Python tips", "--json"],
    capture_output=True,
    text=True
)
data = json.loads(result.stdout)

Return Result Format

Web Search Results

[
  {
    "title": "Result Title",
    "href": "https://example.com/page",
    "body": "Page snippet/description..."
  }

Example 3: Chinese Search

uv run scripts/ddgs_search.py "机器学习教程" -r cn-zh -n 8

Example 4: JSON Output Processing

uv run scripts/ddgs_search.py "python tips" --json | jq '.[0].href'

Example 5: Using Proxy

# Via command line argument
uv run scripts/ddgs_search.py "query" --proxy http://1.2.3.4:8080

# Via HTTP_PROXY environment variable
export HTTP_PROXY="http://proxy.example.com:8080"
uv run scripts/ddgs_search.py "query"

# Via DDGS_PROXY environment variable
export DDGS_PROXY="socks5://127.0.0.1:9150"
uv run scripts/ddgs_search.py "query"

FAQ

uv Not Installed

# macOS/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

# Or run in the script directory (uv will auto-handle)
cd skills/ddgs-search
uv run scripts/ddgs_search.py "query"

Empty Search Results

• Check network connection
• Try changing the --backend parameter (auto/html/lite)
• Some regions may require a proxy (see Proxy Configuration)

Proxy Not Working

• Verify proxy format: http://host:port or socks5://host:port
• Check if authentication is required: http://user:pass@host:port
• Ensure the proxy server is accessible from your network
• Try using HTTP_PROXY environment variable instead of command line argument

Rate Limiting

DuckDuckGo has implicit rate limiting. If frequent requests fail:

• Reduce request frequency
• Add delays between requests
• Use a different backend

Dependencies

• Python 3.9+
• uv (package manager)
• ddgs >= 8.0.0
