Yinsheng Premium Assistant

Problem

In day-to-day Yinsheng agent operations, merchant, device, transaction, profit, cashback, and wallet data are scattered across multiple APIs. Manual checks can miss records, mix subordinate accounts, or mistake aggregated statistics for transaction line items. This skill turns common operational questions into natural-language queries and explicitly limits itself to read-only querying, analysis, and export; it does not perform binding, unbinding, fee changes, filing submissions, or withdrawals.

Core Capabilities and Workflow

• Session handling: It uses tools such as prepareQrLogin, getLoginDataByRequestId, and getValidToken to establish and maintain the login state, reducing repeated QR logins.
• Data lookup: It supports queryMerchants, merchantInfo, queryDevices, deviceInfo, queryTradeByNaturalLanguage, queryProfitByNaturalLanguage, queryWalletBillByNaturalLanguage, queryCashbacks, and dashboardStatistics, covering merchants, devices, transactions, profits, wallets, cashbacks, agents, logs, and policies.
• Report export: Transactions, profits, wallet bills, error logs, operation logs, and agent data can be exported as CSV through scripts such as scripts/export_trade.py and scripts/export_profit.py, using streaming downloads instead of manual parameter assembly.
• Data-scope controls: Money aggregation should use sum_money() and fmt_money() to avoid floating-point artifacts, while multi-user sessions should anchor on the logged-in uid and validate the uid scope to prevent cross-account contamination.

Fit and Caveats

The skill is suitable for agents or operators who need read-only lookups, data reconciliation, and report exports. It is not suitable for write actions; requests such as unbinding, fee updates, filing, or withdrawal should be routed to the responsible business channel. Before calling MCP tools, parameter names must be checked against the schema, especially merchNo versus merchantId. Structured transaction queries expect millisecond timestamps, so the natural-language entry point is the safer option.
