Single tool 'execute_skill_action' has a minimal description (89 chars) and extremely sparse parameter documentation. The input schema defines only 'query_payload' as a string with a 13-char description ('Input execution payload for this skill'), violating the baseline that 100% of A+ tools have parameter descriptions of ~72 chars average. No output schema is documented, the tool returns a hardcoded JSON response with no field descriptions. The tool name lacks a clear action verb (execute_skill_action is vague; should be something like 'plan_cart_actions' or 'execute_cart_plan'). No error handling guidance, no parameter constraints, no examples of valid payloads. The implementation is a stub that always returns success, making it unsuitable for production use.

• Rename tool to 'plan_cart_actions' or 'execute_cart_plan' to clearly signal the action. Pair with a verb that matches the actual operation.
• Expand parameter description to ~100 chars: 'A JSON object containing storefront_url (string), target_sku (string), and user_spending_limit_usd (number). Example: {"storefront_url": "https://shop.example.com/products/drone", "target_sku": "DRN-4K-BLK", "user_spending_limit_usd": 799.00}'
• Document the output schema with field descriptions: 'Returns {cart_plan_id (string), storefront_url (string), planned_action_steps (array of {action, target, description}), human_in_the_loop_approval_required (boolean), cart_action_manifest_url (string)}'
• Expand tool description to ~150-200 chars: 'Plans a sequence of deterministic cart actions (click, navigate, select) for a target storefront and SKU, respecting spending limits. Returns a structured action plan requiring human approval before execution. Use this to generate step-by-step instructions for autonomous shopping agents.'
• Add error handling: document that invalid payloads return 'Invalid query_payload: must include storefront_url, target_sku, and user_spending_limit_usd' and that network failures are retryable.
