This server has fundamental quality gaps that limit agent usability. All 4 tools are defined with descriptions and basic schemas, but there are critical deficiencies: (1) Tool descriptions are generic and lack actionable context for LLM selection, they read like API docs rather than agent guidance; (2) Parameter descriptions are verbose and include implementation details but lack constraints (enums, formats, ranges) that would guide LLM input; (3) No output schemas are documented, agents cannot see what fields to expect from responses; (4) No error handling guidance, tools return raw errors without recovery suggestions; (5) Tool names use 'get_' prefix consistently, which is good, but descriptions do not explain WHEN to call each tool vs alternatives; (6) Parameter naming is inconsistent and domain-specific (client_type/node_type with Chinese-language enum values) without clear validation; (7) No pagination or result limiting is documented, despite tools likely returning variable result sets.

• Add formal JSON Schema output definitions for each tool. Document return types as typed objects with fields like { items: [{id, title, url}], total_count, next_cursor }. This enables agents to chain tools and extract specific fields.
• Convert inline enum descriptions to constrained parameter definitions. Use JSON Schema enum for node_type, with values per client_type. E.g., if client_type='客户端节点', node_type must be one of [查询节点, 运算节点, 执行节点, 流程控制节点, 其它节点]. Make this a validation rule, not prose.
• Add WHEN context to tool descriptions. Example for get_guide: 'Call this after get_navigation to fetch detailed tutorial content for a specific section. Returns the full tutorial with images, tables, and code examples. Use when you need implementation details beyond the navigation summary.'
• Add pagination parameters to get_navigation and get_node_graphs: accept page (default 1) and limit (default 20, max 100). Document return structure to include total_count and has_next_page so agents know if more results exist.
• Replace raw error messages with actionable recovery guidance. E.g., instead of '获取导航失败: {error}', return 'Failed to fetch navigation (network timeout). This is retryable, try again in 5 seconds. If this persists, the service may be down.' with error classification (retryable/fatal).
• Add mutual exclusivity and conditional logic documentation. For get_node_graph_details, document: 'node_type must match the type options available for the specified client_type. See get_node_graphs for valid combinations.'
