This server has 2 tools with basic schemas and descriptions. Both tools have verb-noun naming (get_, search_) which is good. However, descriptions are minimal (12-18 words), parameter descriptions are sparse, output schemas are undocumented, and error handling is generic. The server lacks the structured output guidance, parameter constraints, and recovery instructions that would guide an LLM to use these tools effectively. Tool implementations show OAuth complexity but this is not reflected in or explained by the tool definitions themselves.

• Expand tool descriptions to 80-150 characters and include WHEN to use, WHAT it returns, and any prerequisites. Example: 'get_lark_doc_content: Retrieve the full text content of a Lark document (docx or wiki) by URL. Returns raw document content as a string. Requires valid Lark OAuth credentials (auto-refreshed). Use this to extract document text for analysis or Q&A.'
• Document output schemas explicitly. Add to tool definitions: 'Returns: A string containing the raw document content. In case of error, returns a descriptive error message (user_error: invalid URL format; auth_error: token refresh failed; system_error: API unavailable).' For search_wiki: 'Returns: JSON array of objects with fields {title: string, url: string, create_time: ISO8601 string, update_time: ISO8601 string}. Includes pagination metadata {total_count: integer, has_more: boolean}.'
• Add parameter constraints: search_wiki page_size description should state 'Integer, range 1 - 100 (default: 10). Limits the number of results per query. API may return fewer results if fewer items match.' documentUrl should specify 'Must be a valid Lark document URL with format: https://[subdomain].feishu.cn/(docx|wiki)/[document_token] or https://[subdomain].feishu.cn/(docx|wiki)/[document_token] (/path)?'
• Add error classification and recovery hints to tool descriptions. Example: 'On error, the tool returns a descriptive message. User-fixable errors (invalid URL, document not found, permission denied) suggest corrective actions. Auth errors (token expired) are retried automatically. System errors (API timeout) can be retried.'
