Server has 4 tools with basic schemas and descriptions, but significant gaps limit production readiness. All tools have descriptions (10-50 chars, below ideal 50-200 char range) and input schemas with type definitions. However, parameter descriptions are minimal or missing context. gdrive_search lacks pageSize/pageToken descriptions explaining constraints. gsheets_read has optional parameters (ranges, sheetId) but no guidance on behavior when omitted. No output schemas documented. Error handling is absent, tools return generic failures without recovery guidance. No tool annotations (readOnlyHint/destructiveHint). Naming is clear (verb_noun pattern) but descriptions are too terse to guide LLM selection effectively.

• Expand tool descriptions to 50-200 chars. Example: 'gdrive_search' → 'Search for files in Google Drive by name or query. Returns file IDs, names, and MIME types. Use this to locate files before reading or updating them.'
• Document all parameter constraints in descriptions. Add to gdrive_search: 'pageSize: number of results per page, 1 - 100 (default 10). pageToken: pagination cursor from previous response.'
• Add output schema documentation to each tool. Example for gdrive_search: 'Returns {files: [{id, name, mimeType}], nextPageToken?: string}'.
• Implement error recovery guidance. When gdrive_read_file fails with 'File not found', return: 'File ID not found. Try gdrive_search(query=<filename>) to locate it.'
• Add tool annotations via inputSchema or capability flags. Mark gsheets_update_cell with destructiveHint=true; mark read tools with readOnlyHint=true.
