pi-web-search

A shareable pi package that adds a web_search tool.

The tool searches the web and returns ranked results with titles, URLs, and snippets. It can use Brave Search when an API key is available, or DuckDuckGo HTML without an API key.

Install

Install directly from git:

pi install git:github.com/narumiruna/pi-web-search

Or install from a local checkout:

pi install /absolute/path/to/pi-web-search
# or, for this project only:
pi install -l ./pi-web-search

If published to npm, install with:

pi install npm:@narumitw/pi-web-search

To try it for one run without adding it to settings:

pi -e git:github.com/narumiruna/pi-web-search
# or
pi -e /absolute/path/to/pi-web-search

Security note: pi packages can execute code with your user permissions. Review packages before installing them.

Tool

web_search searches the web and returns source URLs with snippets.

Parameters:

• query (string, required): search query
• max_results (integer, optional): number of results, 1-10, defaults to 5
• provider (auto | brave | duckduckgo, optional): defaults to auto
• safe_search (boolean, optional): defaults to true

Providers

• auto: uses Brave Search when BRAVE_SEARCH_API_KEY is set; otherwise uses DuckDuckGo HTML.

• brave: uses the Brave Search API and requires:

  export BRAVE_SEARCH_API_KEY=...

• duckduckgo: no API key required; scrapes DuckDuckGo's HTML endpoint, so it may be less reliable than an API-backed provider.
