RusyaSearch has 14 tools with basic schemas and descriptions, but significant quality gaps prevent production use. Tool names lack clear action verbs (rusya_* prefix is branding, not semantic). Descriptions are verbose (200-400 chars) and marketing-focused rather than LLM-optimized. Parameter descriptions exist but lack constraints (enums, ranges, patterns). Output schemas are not documented. Error handling is absent, no recovery guidance, no categorization. Security concerns: no visible input validation, no rate limiting, no audit logging. The codebase shows async HTTP calls but no error boundaries or timeout handling.

• Rename tools to use action verbs: search_web, browse_url, extract_content, research_topic, search_scholar. Drop 'rusya_' prefix or use it as a namespace suffix.
• Document output schemas for all tools. Example: rusya_search returns {query, total_results, results: [{rank, title, url, snippet, source}], timestamp}. Include field types and descriptions.
• Add enum constraints to parameters. 'sources' should be enum [all, web, reddit, arxiv, github, stackoverflow, local]. 'target' in rusya_extract should be enum [markdown, clean_html, text, tables, lists, links, images, pdf_ocr].
• Wrap all external API calls in try-catch with timeout handling. Return structured errors: {error: 'timeout', message: 'Brave search took >12s. Try a simpler query.', retryable: true}.
• Add input validation: validate URLs with urllib.parse, sanitize query strings, enforce max_chars bounds (500-50000). Return validation errors with the invalid value and constraint violated.
