Single tool (ddg_search) with minimal schema and description. Tool name lacks action verb prefix (should be 'search_web' or 'web_search'). Description is adequate (127 chars, within 10-1024 range) but parameter lacks type annotation in visible schema. Input schema shows only 'query' as string with basic description, no validation constraints, enums, or format specifications. No output schema documented. No error handling guidance. No pagination support despite search results being inherently paginated. Tool definition appears complete but lacks production-grade rigor.

• Rename tool to 'search_web' and update description to start with action verb: 'Search the web using DuckDuckGo...'
• Document output schema with fields: results (array of {title, url, snippet, source}), total_results (int), has_more (bool), next_cursor (string optional).
• Add parameters: limit (1-50, default 10), offset (0+, default 0) to enable pagination and prevent context window exhaustion.
• Add query parameter constraints in description: 'Natural language or DuckDuckGo operators (site:, -word, etc.). Max 500 chars. Avoid special characters unless escaped.'
• Add error handling section to description: 'Returns error if query is empty, network fails, or rate limit exceeded. Retry with exponential backoff on rate limit (429).' Include actionable recovery guidance.
