This server has severe definition quality issues. Tool 1 (execute_skill_action) is inferred from a supported_tools declaration with no explicit schema, description, or parameter definitions visible in the source code. Tool 2 (onboard_independent_retailer) has a basic description and input schema with three parameters, but the schema lacks proper JSON Schema structure (no 'type' field visible at parameter level in the declaration), descriptions are minimal (under 20 chars for some), and there is no documented output schema. Neither tool has error handling guidance, recovery paths, or security considerations. The server provides no tool annotations, no pagination support, and no structured error responses. This is a minimal proof-of-concept implementation far below production standards.

• Add explicit JSON Schema definitions for execute_skill_action with required parameters, types, and descriptions. Currently inferred only from supported_tools declaration.
• Document output schemas for both tools. For onboard_independent_retailer, specify that the response includes retailer_account_id, shop_name, category, welcome_voucher_discount_eur, net_60_days_working_capital_credit_approved, free_pan_european_shipping_unlocked, and minimum_order_quantity_per_brand_eur with types.
• Convert primary_category to an enum constraint listing all valid categories (Artisan_Home_Decor, Sustainable_Beauty_Wellness, etc.) instead of free-form string. Add descriptions for each parameter explaining constraints and format.
• Add error handling: return structured errors with actionable guidance. E.g., 'Invalid category: got "Artisan_Home_Decor_Invalid", valid categories are: Artisan_Home_Decor, Sustainable_Beauty_Wellness, ...' and 'Duplicate shop name detected. Try a unique name or contact support.'
• Split onboard_independent_retailer into smaller, single-responsibility tools if the bundled operations (account creation, credit approval, shipping setup) can fail independently. This enables agents to handle partial failures and retry specific steps.
