Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| web_searchA | Performs a web search using SearXNG and returns structured JSON results. IMPORTANT: Pagination is offset-based, NOT page-based.To get a specific range of results, set 'offset' to the zero-based index of the first result you want, and 'max_results' to how many results you want. For example, to get results 40-43, set offset=39 and max_results=4. Pagination: Use offset (not page) - offset=0=first result, offset=10=11th resultExample: offset=39, max_results=4 gets results 40-43 |

Scored across 1 tool
Only one tool exists, so there is no possibility of confusion or overlap. The tool's purpose is clearly defined.
With a single tool named 'web_search', naming is self-consistent and follows a clear verb_noun pattern.
One tool for a search server is on the low end, but for simple web search it may be sufficient. However, SearXNG typically offers multiple search types (images, news, etc.), so the scope seems narrow.
The tool only provides basic web search with offset pagination. No support for categories, language, filetype, or other SearXNG features, leaving significant gaps for a comprehensive search interface.
