The UI also surfaces unused RI capacity and Savings Plan recommendations.</li>\n<li>Savings Plans: compute-based Savings Plans provide flexibility across ECS instance families, sizes, and regions in exchange for a 1-year or 3-year hourly commitment. ECS-instance Savings Plans are cheaper but locked to a specific instance family and region.</li>\n<li>Reserved Instances lock capacity for 1 or 3 years. Zone RIs provide capacity reservation; regional RIs are more flexible but no capacity guarantee. Partial and all-upfront payment options exist.</li>\n<li>MaxCompute billing mode (CU package vs. on-demand) is the single biggest cost lever for big data. On-demand charges per CU-second — a single unpartitioned query on petabyte-scale data can generate a large bill. CU packages are prepaid fixed compute.</li>\n<li>Resource tags must be applied consistently — untagged resources are unattributable in Cost Manager. Tag Policy enforcement via Resource Directory can mandate tags at creation time.</li>\n<li>Budget alerts require SNS/MNS integration to trigger notifications. Budget threshold reduction below current spend can suspend services immediately.</li>\n</ul>\n<h2>Lean operating rules</h2>\n<ul>\n<li>Prefer official Alibaba Cloud documentation and live evidence over memory or inference.</li>\n<li>Separate confirmed facts from inference. If RI coverage rate, Savings Plan utilization, or tag coverage was not queried or shown, say so.</li>\n<li>Challenge untagged resources, on-demand MaxCompute for predictable workloads, RI purchases without utilization verification, and budget thresholds below current spend.</li>\n<li>Keep answers scoped, reversible, and explicit about trade-offs and open questions.</li>\n<li>Load references only when needed; do not pull all deep guidance into short answers.</li>\n</ul>\n<h2>References</h2>\n<p>Load these only when needed:</p>\n<ul>\n<li><a href=\"references/workflow-and-output.md\">Workflow and output contract</a> — use when executing the full FinOps review, cost analysis, or formatting the final answer.</li>\n<li><a href=\"references/official-sources.md\">Official sources</a> — use when grounding Alibaba Cloud BSS or billing service behavior or checking the detailed source list.</li>\n</ul>\n<h2>Response minimum</h2>\n<p>Return, at minimum:</p>\n<ul>\n<li>the scoped target and evidence level,</li>\n<li>the top spend drivers and attribution gaps,</li>\n<li>the Savings Plan/RI coverage assessment,</li>\n<li>the MaxCompute billing mode recommendation,</li>\n<li>the tagging strategy and enforcement gaps,</li>\n<li>the safest next actions with validation steps,</li>\n<li>the assumptions or blockers that prevent stronger conclusions.</li>\n</ul>\n","files":[{"path":"metadata.json","sizeBytes":970,"isText":true},{"path":"references/official-sources.md","sizeBytes":578,"isText":true},{"path":"references/workflow-and-output.md","sizeBytes":1629,"isText":true},{"path":"SKILL.md","sizeBytes":4085,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
