Critical gaps across all dimensions. Descriptions are present but minimal (10-50 chars, well below 194-char baseline). No input schemas visible in source, only parameter names and types mentioned in test context. No output schemas documented. No error handling guidance. No tool annotations. The server appears to be a health data integration layer, but the actual MCP tool registration mechanism is not visible in provided source.

• Locate and provide the actual MCP tool registration code (likely in core/mcp or integrations/health modules). Current evaluation is based on test files, which do not show the canonical tool definitions.
• Expand tool descriptions to 100-200 chars. Example: 'list_record_types' should explain what record types are available (e.g., steps, heart rate, sleep), when to call it first, and what the response structure is.
• Document input schemas explicitly with JSON Schema: types, required fields, enums for constrained values, and format/pattern for strings. For 'date' parameters, specify ISO 8601 format and valid range (e.g., last 365 days).
• Document output schemas for each tool. Specify field names, types, and units. E.g., get_steps should return {date: string, steps: number, unit: 'steps'}.
• Add error handling guidance: 'If date is invalid, return error with format hint. If no data available for date, return empty result with explanation rather than 500 error.'
