This server has critical definition gaps. Tool descriptions are present but minimal (10-30 chars), falling well below the 50-200 char LLM-optimized baseline. Most parameters lack descriptions entirely: search_feeds has only 'keyword' described; publish_content has 5 params but only 2-3 with meaningful descriptions. No input schemas are visible in the source code, only parameter names and types are inferred from the tool call examples in login.py and publish.py. Output schemas are completely undocumented. Error handling is minimal: no recovery guidance, no categorization of retryable vs fatal errors. The publish_content tool is IRREVERSIBLE but has no confirmation/dry-run pattern. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) are present.

• Add explicit JSON Schema definitions for all 5 tools with full type declarations, required fields, and constraints. Publish in the MCP server's tools/list response.
• Expand tool descriptions to 80-150 chars. Example: 'check_login_status: Returns current Xiaohongshu login state. Call before publish_content to verify session is active. Returns {logged_in: bool, username: string, expires_at: ISO8601}.'
• Add parameter descriptions for all fields. For publish_content visibility, use enum constraint: ['公开可见', '仅自己可见', '仅互关好友可见']. For schedule_at, specify ISO8601 format and future-only constraint.
• Implement confirmation pattern for publish_content: add a dry_run parameter (bool, default false) or a separate publish_content_preview tool that returns validation errors without posting.
• Document output schemas inline in tool descriptions or in a separate schema registry. Example: 'search_feeds returns {results: [{id, title, author, likes, comments}], total: int, next_cursor: string}'.
