Server has 14 tools with mostly complete schemas and descriptions, but quality is inconsistent. Naming follows verb_noun convention well (search_bookmarks, get_bookmarks, export_bookmarks). Descriptions are present but often generic (e.g., 'Get all bookmarks with optional filtering and pagination' lacks context on when to use vs search_bookmarks). Parameter schemas are well-typed with enums and constraints (e.g., search_mode enum, format enum in export_bookmarks), but descriptions for some parameters are minimal. Output schemas are documented in Pydantic models (BookmarkResult, SearchResults, AnalyticsReport) but not visible in tool definitions themselves. Error handling is absent from tool definitions, no guidance on recovery or retryability. Tool composition is reasonable (separate search, get, export tools) but some tools combine multiple concerns (get_bookmark_analytics includes duplicates, folder analysis, domain analysis, health scoring in one call).

• Expand tool descriptions to 50-200 characters with explicit context: 'Search bookmarks using fuzzy, exact, or semantic matching. Use this for keyword queries. For browsing all bookmarks, use get_bookmarks instead.' This disambiguates from similar tools.
• Add error handling guidance to each tool definition. E.g., reload_bookmarks: 'May fail if Edge profiles are locked. Ensure Edge is closed before retrying. If persistent, check file permissions.'
• Split get_bookmark_analytics into separate tools: get_duplicate_analysis, get_folder_analysis, get_domain_analysis, get_health_score. Agents can then request only what they need.
• Document output schemas in tool descriptions or as a structured 'returns' field. E.g., 'Returns: {title, url, folder, date_added, score, tags, description, profile}' so LLMs know what to expect.
• Add confirmation step for destructive operations. E.g., backup_bookmarks should return 'Ready to backup to /path/backup.json. Confirm?' and require a confirm_backup tool call before executing.
