Both tools have minimal descriptions (under 100 chars) and lack parameter descriptions entirely. Input schemas are present with basic types (string, number) but no constraints, enums, or validation guidance. No output schema documented. Tools perform write operations (BUY/SELL) with no error handling, confirmation patterns, or recovery guidance. No security considerations visible (credentials hardcoded in trade.ts). Naming is acceptable but descriptions fail to explain WHEN to use each tool or what happens on failure.

• Add parameter descriptions: 'stock: NSE trading symbol (e.g., RELIANCE, TCS). Must be 1-10 uppercase letters.' and 'qty: Number of shares to trade. Must be a positive integer (1-10000).'
• Document output schema with structured fields: {order_id, status, symbol, quantity, price, timestamp, exchange}. Return actual order details from KiteConnect response, not generic text.
• Move credentials to environment variables (ZERODHA_API_KEY, ZERODHA_API_SECRET, ZERODHA_ACCESS_TOKEN). Load via process.env in trade.ts. Never commit secrets to source.
• Add error handling with recovery guidance: 'Insufficient funds. Check account balance via get_account_balance() before retrying.' or 'Market closed. Orders can only be placed during trading hours (09:15-15:30 IST).'
• Implement confirmation pattern for destructive operations: add a 'confirm' boolean parameter (default false) or return a 'requires_confirmation' response that forces the agent to call a separate confirm_order() tool before execution.
