30 tools with consistent naming (verb_noun pattern) and basic schemas, but critical gaps in descriptions and parameter documentation. All tools have input schemas with types, but descriptions are minimal (10-50 chars, well below the 194-char baseline). Parameters lack depth: no enums for constrained values (e.g., 'role' accepts free-form strings instead of enum), no format constraints, no validation guidance. Output schemas are undocumented, LLMs cannot predict response structure. Error handling is generic ('Error: {e}') with no recovery guidance. Security concerns: no indication of permission gates on destructive operations (delete_doc, ms_delete_document). Composition is reasonable (single responsibility per tool), but chaining is weak, responses don't guarantee all IDs needed for follow-up calls.

• Expand all descriptions to 100-200 chars. Include WHAT the tool does, WHEN to use it (vs. similar tools), and what it returns. Example: 'List Google Docs in your account (up to 20). Returns doc_id, title, and last_modified_time. Use this to discover available docs before calling google_get_doc.'
• Convert 'role' parameters to enums. Define: role: enum ['reader', 'writer', 'commenter'] with description 'Permission level: reader (view only), writer (edit), commenter (comment only).'
• Document output schemas for all list/search/get tools. Specify returned fields, types, and whether results are paginated. Example: 'Returns array of {doc_id: string, title: string, last_modified: ISO8601, owner_email: string}. Limited to 20 results; use limit param for pagination.'
• Replace generic error handling with actionable messages. Categorize errors: 'Not found: Try search_google_docs() with a partial title.' or 'Permission denied: Ensure you have write access to this doc.' or 'Rate limited: Retry in 60 seconds.'
• Add confirmation step for destructive operations. Implement a dry-run parameter or a separate confirm_delete_doc tool. Document: 'This operation is irreversible. Call with confirm=true only after user approval.'
