websearch

name	websearch
description	Use when the user wants a live web search run against their local SearXNG instance — looking something up online, finding current information, or configuring the SearXNG endpoint. Triggers on: "websearch", "search the web", "look this up online", "find online", "searx", "/skill:websearch".

Websearch via SearXNG

Search the web using a locally installed SearXNG instance.

Endpoint Configuration

The SearXNG endpoint persists across session turns. Store it once, reuse until changed.

Config file: ~/.pi/agent/websearch-config.json

Set endpoint:

/skill:websearch url <endpoint_url>

Example:

/skill:websearch url http://localhost:8080

This writes {"endpoint": "http://localhost:8080"} to the config file. All subsequent searches use this endpoint until the user sets a new one.

If no endpoint is configured, tell the user:

No SearXNG endpoint configured. Set one with: /skill:websearch url <endpoint_url>

Do NOT guess or assume a default endpoint. If the config file doesn't exist, ask.

Performing Searches

When the user wants to search the web:

1. Read the endpoint from ~/.pi/agent/websearch-config.json
2. Build the search URL: {endpoint}/search?q={url_encoded_query}&format=json
3. Fetch results with curl (or equivalent)
4. Parse the JSON response and present results

Search URL Construction

GET {endpoint}/search?q={query}&format=json&language={lang}&categories={cats}&time_range={range}&pageno={page}&safesearch={level}

Only include optional parameters when the user explicitly requests them. Always URL-encode the query string.

Example

curl -s 'http://localhost:8080/search?q=python+async+patterns&format=json&language=en' | python3 -m json.tool

Optional Parameters

Parameter	Values	When to use
language	ISO 639-1 code (e.g., en, pl, de)	User specifies a language
categories	Comma-separated (e.g., general,news)	User narrows to specific categories
time_range	day, month, year	User specifies recency
pageno	Integer (default 1)	User paginates
safesearch	0, 1, 2	User requests safe search

Result Format

Present results in this format:

## Search Results: "{query}"

1. [{Title}]({url})
   {snippet}

2. [{Title}]({url})
   {snippet}

Rules:

• Show title as a link with the URL
• Include the snippet/description below each result
• Number the results
• If results are empty, say "No results found for: {query}"
• If the request fails, show the error clearly

Error Handling

• Connection refused / timeout: "Cannot reach SearXNG at {endpoint}. Is it running? Check with curl {endpoint}"
• HTTP 403: "Format not enabled on this instance. The SearXNG admin must enable JSON (or CSV/RSS) output in settings.yml under the search.formats key. Without it, all /search?format=json requests return 403."
• HTTP 4xx/5xx: Show the status code and response body
• Invalid JSON: Show raw response for debugging
• Missing results field: Show full response structure for debugging

Enabling formats on the instance

If the instance returns 403, the admin needs to ensure formats includes json in settings.yml:

search:
  formats:
    - html
    - json
    - csv
    - rss

Then restart SearXNG.

Response Parsing

SearXNG JSON response structure:

{
  "results": [
    {
      "title": "...",
      "url": "...",
      "content": "snippet text...",
      "engine": "google",
      "score": 1.0
    }
  ],
  "number_of_results": 42,
  "query": "...",
  "engines": [...]
}

Extract from each result: title, url, content (snippet), engine.
