-- Allows Claude to search the web using DuckDuckGo and use the results to inform responses
-- Provides up-to-date information for current events and recent data
-- Returns search result information formatted as search result blocks, including links as markdown hyperlinks
-- Use this tool for accessing information beyond Claude's knowledge cutoff
+- Allows VersperClaw to search the web using a local SearXNG search engine and use the results to inform responses
+- Provides up-to-date information for current events, technical documentation, and recent data
+- Returns structured search results including titles, URLs, and snippets
 - Works with all AI providers including local models
-
-CRITICAL - DOMAIN FILTERING RULES:
-  - NEVER use allowed_domains or blocked_domains parameters unless the user EXPLICITLY requests it
-  - ALWAYS search ALL domains by default - no automatic domain restrictions
-  - DO NOT infer domain preferences from the query content (e.g., don't limit to social media for "latest news")
-  - Leave allowed_domains and blocked_domains parameters UNSET (not provided) for normal searches
+- Designed for high-recall search to support reasoning and retrieval-augmented generation (RAG)
 
 Search Strategy:
-  - Uses DuckDuckGo search to retrieve web search results
-  - May encounter CAPTCHA challenges on some searches, which will return no results
-  - Try rephrasing your query if no results are returned
+  - Uses SearXNG metasearch engine (aggregates multiple sources)
+  - Results may vary in quality; prioritize relevance and credibility
+  - If results are weak or empty, try rephrasing the query
+  - Prefer more specific queries when possible (add keywords, version numbers, or context)
 
 CRITICAL REQUIREMENT - You MUST follow this:
   - After answering the user's question, you MUST include a "Sources:" section at the end of your response
-  - In the Sources section, list all relevant URLs from the search results as markdown hyperlinks: [Title](URL)
+  - In the Sources section, list relevant URLs from the search results as markdown hyperlinks: [Title](URL)
   - This is MANDATORY - never skip including sources in your response
-  - Example format:
-
-    [Your answer here]
+  - Only include sources that are actually useful and referenced in your answer
 
-    Sources:
-    - [Source Title 1](https://example.com/1)
-    - [Source Title 2](https://example.com/2)
+Search Best Practices:
+  - Use multiple searches if needed (broad → narrow)
+  - Use precise technical terms for programming-related queries
+  - For news or recent events, include time context (e.g., year, month)
+  - Do NOT assume the first result is correct — synthesize across multiple sources
 
 IMPORTANT - Use the correct year in search queries:
-  - The current month is ${currentMonthYear}. You MUST use this year when searching for recent information, documentation, or current events.
-  - Example: If the user asks for "latest React docs", search for "React documentation" with the current year, NOT last year
+  - The current month is ${currentMonthYear}
+  - You MUST use this year when searching for recent information, documentation, or current events
+  - Example: If the user asks for "latest React docs", search with the current year, NOT outdated versions
+
+Behavior Guidelines:
+  - Focus on gathering information, not filtering it prematurely
+  - Prioritize recall first, then rely on reasoning to refine
+  - Avoid hallucinating information when search results are insufficient — instead, search again
