Critical gaps across all dimensions. Tool 'add' lacks any description (0/100). Parameters across all tools have null descriptions, violating the requirement that every parameter must explain what it controls. Tool schemas use Zod but lack formal JSON Schema documentation. Irreversible tools (buy-stock, sell-stock) have no confirmation/dry-run pattern, no error guidance, and no permission gates. No output schemas documented. Naming is acceptable (verb_noun pattern) but descriptions are minimal or absent. This server would not pass production code review.

• Add non-empty descriptions to every parameter. Example: 'stock': 'The trading symbol (e.g., RELIANCE, INFY). Must be a valid NSE-listed stock.'
• Add a description to the 'add' tool explaining its purpose and when to use it (e.g., 'Performs basic arithmetic addition of two numbers').
• Implement a confirmation step for buy-stock and sell-stock. Return a 'confirm_order' tool or require explicit confirmation before executing real trades.
• Document output schemas for all tools. Example for get-profile: 'Returns {broker: string, email: string, ...}' with field descriptions.
• Add error handling that guides recovery. Example: 'Stock symbol not found. Call list_available_stocks() to see valid symbols.' instead of generic messages.
