Critical gaps across all dimensions. Tool definitions are inferred from test files rather than explicit registration code, capping individual scores at 50. Descriptions are present but generic (10-50 chars). No input schemas visible in source, cannot verify parameter types, constraints, or structure. 'initialize' and 'ping' are protocol-level concerns, not user-facing tools. 'tools/call' accepts free-form 'arguments' object with no schema validation. No output schemas documented. Error handling and recovery guidance absent.

• Move 'initialize' and 'ping' out of the tool registry. These are MCP protocol concerns, not user-facing capabilities. Implement them in the protocol layer (e.g., via the MCP server's initialize and ping handlers).
• Document complete input schemas for all tools in the tool registration code. For 'tools/call', enumerate valid capability names and their required/optional parameters with types and descriptions. Use JSON Schema with $ref to avoid duplication.
• Add output schemas to tool definitions. Document what 'tools/list' returns (e.g., array of {name, description, inputSchema}) and what 'tools/call' returns (e.g., {success, result, error}).
• Expand tool descriptions from 10-50 chars to 50-200 chars. Include WHAT the tool does, WHEN to use it, and any prerequisites. E.g., 'tools/call': 'Execute a database capability through the agent. Requires the capability name and valid parameters matching the schema from tools/list. Returns structured result or error with recovery guidance.'
• Implement error handling with recovery guidance. When 'tools/call' fails, return {error, reason, suggestion}. E.g., 'Capability not found. Available capabilities: [list]. Call tools/list to discover valid options.'
