Read-only cost diagnostics and audits for Alibaba Cloud database products (RDS, Redis, MongoDB, PolarDB, DTS, DBS, CDT): explain a high or spiking DB bill with billing-item breakdowns and month-over-month anomaly attribution, and run proactive audits of renewal/expiry risk, idle instances, and optional paid features — never modifying any resource. Triggers: "why is my database bill so high", "DB cost spike", "database cost anomaly", "database bill surged", "unexpected database charges", "unexplained database charge", "don't know what feature is charging me", "RDS bill breakdown", "billing item breakdown", "charged after instance deleted", "released instance still billed", "monthly DB cost trend", "cost increase root cause", "CDT bill", "cost audit", "database cost audit", "idle database instance", "idle instance still charging", "renewal lock", "about to expire", "unexpected auto-renewal charge", "DMS charges", "DAS billing".

What this skill does
DB Cost Diagnosis Diagnose Alibaba Cloud database costs: "why is my database bill so high", "which billing item dominates this RDS instance's charge", "my DB cost jumped this month — what caused it", "I deleted the instance, why am I still being billed", "which instances are about to expire", "am I paying for idle databases", "what paid feature is charging me". Core approach: confirm identity and billing scope, then either (1) drill into a single instance's bill detail with billing-item split to locate the dominant cost driver, (2) aggregate the account-level DB cost trend over recent months, detect anomalies, and attribute them to specific products and instances, or (3) run a proactive read-only audit — renewal/expiry risk and order anomalies, idle/low-load detection, or paid-feature attribution for unexplained charges. Conclude with evidence-based findings only; this skill never changes anything. Absolute Rules 1. ABSOLUTE PROHIBITION (read-only enforcement): Under NO circumstances may you generate, write, or execute any command/script calling a mutating API — e.g. Modify, Delete, Create, Restart, Release, Upgrade, Downgrade, or any configuration/spec change on database resources. This includes commands "for the user to run manually". If the user asks to downgrade, release, or resize an instance to cut cost, only output the manual guidance and declare this skill is read-only. 2. API WHITELIST: The only permitted OpenAPI actions are the read-only BSS queries DescribeInstanceBill, DescribeSplitItemBill, QueryOrders, and QueryAvailableInstances (bssopenapi, endpoint business.aliyuncs.com, API version 2017-12-14), the read-only CloudMonitor query DescribeMetricList (cms), plus sts:GetCallerIdentity for identity traceability. Any other action is forbidden. 3. ABSOLUTE PROHIBITION (credential handling): Never read, print, or pass AK/SK/STS tokens explicitly. Credentials are resolved automatically by the aliyun CLI default credential chain. …
