The server demonstrates solid fundamentals with 9 well-structured tools accessing a form/database API. All tools have descriptions (Chinese, reasonably detailed) and explicit input schemas with type definitions. Tool names follow verb_noun convention (list_, get_, query_, create_, update_, delete_). However, there are notable gaps: (1) Output schemas are NOT documented, no clear definition of what each tool returns, forcing LLMs to infer structure; (2) Parameter descriptions are minimal (5 - 20 chars on average) and lack context about valid ranges, formats, or dependencies; (3) Error handling is present but generic ('请求失败: {e}'); (4) Tool composition issues: query_records accepts both 'filters' and 'filter' params with undocumented precedence rules, creating potential confusion; (5) Destructive operations (delete_record) have no confirmation pattern or dry-run equivalent; (6) No documentation of API rate limits or batch size constraints (create_records_batch claims 'max 100' but no validation visible). The tools are functional and well-intentioned, but lack the rigor expected of production agent tools.

• Document return schemas for all tools. Example: list_apps should return {"apps": [{"_id": string, "name": string, ...}], "total": number}. Use JSDoc or OpenAPI format in docstring.
• Expand parameter descriptions to 50 - 150 chars, following pattern: <what it does> + <valid range or values> + <when to use>. Example: 'limit (1 - 100, default 100): Max records to return per page. Larger values increase latency; keep under 50 for production agents.'
• Add enum validation to query_records: either 'filters' (simple dict) OR 'filter' (complex), not both. Use JSONSchema oneOf. Document: 'Pass filters for exact-match queries; filter for complex conditions (lt, gt, like, range). If both present, filter is used.'
• Implement confirmation pattern for delete_record. Return {"status": "confirmation_required", "record_id": "...", "message": "Deleting record, this cannot be undone. Confirm with confirm_delete_record(record_id). Or call list_records to review first."} with a separate confirm_delete_record tool.
• Upgrade error messages to include classification and recovery hints. Example: {"error": "API rate limit exceeded", "type": "retryable", "retry_after_seconds": 60, "hint": "Wait before retrying create_record."} vs {"error": "Invalid app_id: app_xyz does not exist", "type": "user-fixable", "hint": "Call list_apps to see available app IDs."}'
• Add input validation to create_records_batch: check len(data_list) <= 100; return early with clear error if exceeded. Return per-item success/failure: {"status": "partial_failure", "success": 95, "failed": [{"index": 42, "error": "Missing required field 'name'"}], "created_ids": [...]}'.
