DDGo Search Skill

ddgo-search is a resilient, token-efficient CLI wrapper around the DuckDuckGo Search (ddgs) Python library. It provides robust rate-limiting, proxy rotation, webpage extraction, and direct content fetching.

📦 Installation

Before using this skill, ensure ddgo-search is installed. It is recommended to install it globally using uv:

  1. Install uv (if not already installed):

    • macOS/Linux: curl -LsSf https://astral.sh/uv/install.sh | sh
    • Windows: powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

  2. Install ddgo-search:

    uv tool install ddgo-search

  3. Install the Skills and Agent configurations:

    # Install the skills (for Codex, Antigravity, Crush, and Claude Code)
ddgo-search skills install

# Install the agent configurations (for Codex)
ddgo-search agents install --target codex

🚀 Quick Start

Run commands directly (if installed via uv tool install) or using uv run (if executing inside the project directory):

# Text search (default format is ASCII table)
ddgo-search text "artificial intelligence"
# Or: uv run ddgo-search text "artificial intelligence"

# Direct URL fetch and convert to Markdown
ddgo-search fetch "https://example.com" --format markdown
# Or: uv run ddgo-search fetch "https://example.com" --format markdown

🛠️ CLI Reference

Global Options

Pass global options before the subcommand:

  • -p, --proxy TEXT: A single proxy URL, comma-separated list, or path to a file with proxies (one per line).
  • -t, --timeout INTEGER: Request timeout in seconds (default: 10).
  • -r, --max-retries INTEGER: Maximum retries upon server failures or timeouts (default: 3).
  • --verify / --no-verify: Enable/disable SSL certification verification (default: --verify).

Example:

ddgo-search -p "http://proxy.example.com:8080" -t 15 text "latest technology"

Subcommands

1. Text Search (text)

Search the web for text results.

ddgo-search text "python programming" [OPTIONS]
  • --max-results INTEGER: Maximum results to return (default: 10).
  • --timelimit [d|w|m|y]: Limit results to day, week, month, or year.
  • --region TEXT: Region/country code (default: us-en).
  • --safesearch [on|moderate|off]: Content filtering (default: moderate).
  • -f, --format [table|plain|json|csv]: Output format (default: plain).

2. Image Search (images)

Search for images.

ddgo-search images "space nebula" [OPTIONS]
  • --size [Small|Medium|Large|Wallpaper]
  • --color [color|Monochrome|red|green|etc.]
  • --type-image [photo|clipart|gif|transparent|line]
  • --layout [Square|Tall|Wide]
  • --license-image [any|Public|Share|Modify]
  • --region TEXT: Region/country code (default: us-en).
  • --safesearch [on|moderate|off]: Content filtering (default: moderate).
  • -f, --format [table|plain|json|csv] (default: plain).

3. Video Search (videos)

Search for videos.

ddgo-search videos "rust tutorial" [OPTIONS]
  • --resolution [high|standard]
  • --duration [short|medium|long]
  • --license-videos [creativeCommon|youtube]
  • --region TEXT: Region/country code (default: us-en).
  • --safesearch [on|moderate|off]: Content filtering (default: moderate).
  • -f, --format [table|plain|json|csv] (default: plain).

Note: The underlying library standard resolution expects "standart". The CLI enum maps "standard" to "standart" automatically.

4. News Search (news)

Query recent news.

ddgo-search news "climate change" [OPTIONS]
  • --timelimit [d|w|m]
  • --region TEXT: Region/country code (default: us-en).
  • --safesearch [on|moderate|off]: Content filtering (default: moderate).
  • -f, --format [table|plain|json|csv] (default: plain).

5. Book Search (books)

Search DuckDuckGo books.

ddgo-search books "machine learning" [OPTIONS]
  • --max-results INTEGER: (default: 10).
  • -f, --format [table|plain|json|csv] (default: plain).

6. Web Page Extract (extract)

Extract main content using DuckDuckGo's internal extraction backend.

ddgo-search extract "https://example.com" [OPTIONS]
  • -f, --format [text_markdown|text_plain|text_rich|text] (default: text_markdown).
  • -o, --output PATH: Save extracted content to file instead of printing.

7. Direct Web Page Fetch (fetch)

Directly fetch a URL using httpx and convert its HTML content to Markdown, clean text, or raw HTML. This is highly recommended for scraping specific pages bypasses DDG's extract servers.

ddgo-search fetch "https://example.com" [OPTIONS]
  • -f, --format [markdown|text|html] (default: markdown).
  • -s, --max-size INTEGER: Maximum content size in bytes before truncation to preserve tokens (default: 102400 / 100KB).
  • -o, --output PATH: Save content to file instead of printing.

🔍 Scope Limiting & Search Operators

You can narrow down search results by region, time recency, safety settings, or using direct query operators:

CLI Options

  • --region TEXT: Limits results to a specific region/country code (e.g., us-en, cn-zh).
  • --timelimit [d|w|m|y]: Retrieves only recent results from the past day, week, month, or year.
  • --safesearch [on|moderate|off]: Controls content filtering.

Search Operators (within QUERY)

  • site:example.com: Only return results within a specific website.
  • -site:example.com: Exclude a specific website from results.
  • filetype:pdf: Filter by file format (e.g., pdf, doc, ppt).
  • intitle:keyword: Require keyword in the page title.
  • "exact phrase": Match exact word combination.

Example:

ddgo-search text "python site:stackoverflow.com" --timelimit m

💡 Best Practices for Agents

  1. Token Conservation:

    • Use --format plain (default) or --format table instead of json or csv when listing results in a terminal. The plain format is the most token-efficient representation, whereas the custom table format auto-wraps content to fit terminal widths cleanly without truncation.
    • For fetch or extract, use the defaults to get Markdown representation which is easier to comprehend. Adjust --max-size if you want to retrieve smaller chunks of a page to keep tokens under control.

  2. Handling Rate Limits:

    • The CLI has built-in global process-safe rate limiting that enforces a random delay (1.5s - 3.0s) between successive requests across all processes.
    • If you encounter rate limit issues, the CLI will automatically backoff. You do not need to build manual retry loops around CLI invocations; just configure --max-retries and provide reliable proxies if querying heavily.

  3. Proxy Rotation:

    • For high-volume searching, always supply a list of proxies: 
      ddgo-search -p "proxy1,proxy2,proxy3" text "query"
# Or point to a file containing proxies (one per line)
ddgo-search -p "proxies.txt" text "query"
    • The CLI rotates to the next proxy server automatically on failure.
