This MCP server has critical deficiencies in tool definition quality. Only 2 tools are defined, both with minimal descriptions and NO visible input/output schemas in the provided source code. The tool descriptions are generic and under the minimum recommended length (10-20 chars each). No parameter documentation is visible. The server uses agno framework (non-standard MCP) and the actual tool registration and schema definitions are not present in the provided code sample. File paths reference tools in '1_frontend_dashboard/main.py' and '5_hr_efficiency_mcp/start_mcp_server.py' but the source code provided does not show these implementations, only a launcher script and a rebuild_index.py utility. Tool definitions appear to be inferred rather than explicitly visible in the source.

• Provide the complete tool registration code from zhishui_efficiency_mcp module showing tool.register() calls with full input schemas (types, descriptions, constraints).
• Expand tool descriptions to 50-200 characters following the pattern: '[Action]: [What it does]. [When to use it]. [What it returns].' Example: 'Evaluate an employee\'s efficiency metrics. Use this to assess productivity and performance against KPIs. Returns efficiency score (0-100), productivity metrics, and flagged concerns.'
• Define input schemas with explicit types and descriptions for all parameters. Example: { 'employee_id': {'type': 'string', 'description': 'Unique employee identifier (e.g., EMP123)'}, 'period': {'type': 'string', 'enum': ['monthly', 'quarterly', 'annual'], 'description': 'Evaluation period'} }
• Document output schema for each tool. Example for evaluate_employee_efficiency: { 'efficiency_score': {'type': 'number', 'description': 'Overall efficiency rating 0-100'}, 'metrics': {...}, 'recommendations': {...} }
• Add error handling with recovery guidance. Example: 'If employee_id not found, try search_employees() with employee_name first.'
• Migrate from agno to official MCP SDK (Python: mcp library via pip install mcp) to ensure standard protocol compliance and broader client compatibility.
• If multiple similar tools exist (e.g., different report formats), disambiguate via distinct names. Current names are acceptable but ensure they do not overlap with unshown tools.
• Implement parameter validation early. Return actionable errors: 'Invalid period "weekly", must be monthly|quarterly|annual' not generic 400 errors.
