This server exposes 8 API client tools with minimal schema documentation and generic descriptions. Most tools lack parameter type definitions beyond basic strings and objects. Descriptions are present but generic (avg ~50 chars, well below the 194-char baseline). No input validation guidance, no error recovery hints, and no output schemas documented. Tool names follow verb_noun convention (good), but parameter descriptions are sparse. The 'account' parameter in createAccount and updateAccount is an untyped object with only a comma-separated list of fields in the description, no JSON Schema structure. No tool annotations (readOnlyHint, destructiveHint) despite clear risk levels. This is a typical community-grade server with functional but poorly-documented tools.

• Convert the 'account' object parameter in createAccount and updateAccount to a formal JSON Schema with explicit type, required fields, and per-field descriptions. Example: {"type": "object", "required": ["email", "password", "firstName", "lastName"], "properties": {"email": {"type": "string", "description": "Email address for the account"}, ...}}
• Document output schemas for all tools. For getProductsList, specify: {"type": "object", "properties": {"products": {"type": "array", "items": {"type": "object", "properties": {"product_id": {"type": "string"}, "name": {"type": "string"}, "price": {"type": "number"}}}}, "total_count": {"type": "integer"}}}
• Add tool annotations to all tools. Mark deleteAccount with destructiveHint=true. Mark verifyLogin, getUserDetailByEmail, getProductsList, getBrandsList, searchProduct with readOnlyHint=true. Mark idempotent tools (verifyLogin, getUserDetailByEmail, getProductsList, getBrandsList, searchProduct) with idempotentHint=true.
• Expand descriptions to 100-200 characters with context. Example for getProductsList: 'Retrieves all products from the catalog. Returns product_id, name, price, and availability. Use this to show available items; use searchProduct to filter by keyword. Results are paginated; use limit and offset parameters.'
• Add error recovery guidance to descriptions. For deleteAccount: 'Deletes an account permanently. Requires correct email and password. If password is incorrect, error will indicate auth failure, verify credentials and retry. This operation cannot be undone.' For getUserDetailByEmail: 'Looks up user by email. Returns user_id, name, email, and account status. If not found, try searchUser with a partial name or email domain.'
