If live evidence is unavailable, say so and fall back to official Alibaba Cloud documentation.</li>\n<li>Separate confirmed facts from inference. Label each finding explicitly.</li>\n<li>Any change containing deletion of RDS instances, OSS buckets, or KMS keys is irreversible — block and require explicit backup confirmation and written approval before proceeding.</li>\n<li>Never ask for AccessKey IDs, RAM user credentials, OSS bucket names containing customer data, or account IDs.</li>\n<li>Challenge vague rollback plans, missing approval gates, org-level changes without account enumeration, and drift-unchecked applies.</li>\n</ul>\n<h2>Key IaC safety guidance</h2>\n<ul>\n<li><strong>Terraform blast radius</strong>: classify as low (single resource), medium (service-level), high (account-wide), or org-wide (Resource Directory scope). Org-wide changes require explicit member account enumeration.</li>\n<li><strong>ROS deletion protection</strong>: production stacks must have deletion protection enabled — a stack without it can be destroyed in one API call without confirmation.</li>\n<li><strong>ROS drift detection</strong>: run <code>DetectStackDrift</code> before any change set apply — applying against an unknown drift baseline produces unpredictable outcomes.</li>\n<li><strong>Terraform state backend security</strong>: OSS backend bucket must use SSE-KMS encryption, deny public access, and restrict IAM/RAM policy to the CI/CD role only — state files contain resource attribute details including sensitive values.</li>\n<li><strong>Irreversible resource types</strong>: RDS instances, OSS buckets, KMS keys, VPCs with active dependencies — deletion cannot be undone by Terraform or ROS after apply completes.</li>\n<li><strong>Resource Directory scope</strong>: ROS stacks deployed at the Org level through Resource Directory affect all member accounts — enumerate accounts before approving org-level changes.</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 change safety review or formatting the final assessment output.</li>\n<li><a href=\"references/official-sources.md\">Official sources</a> — use when grounding Alibaba Cloud service behavior or IaC provider claims.</li>\n</ul>\n<h2>Response minimum</h2>\n<p>Return, at minimum:</p>\n<ul>\n<li>the change summary and target resources,</li>\n<li>the blast radius classification with rationale,</li>\n<li>all detected deletion and irreversible operations,</li>\n<li>Resource Directory and cross-account scope assessment,</li>\n<li>state drift and conflict risks,</li>\n<li>rollback plan and approval gate completeness verdict,</li>\n<li>safe change sequencing recommendations.</li>\n</ul>\n","files":[{"path":"metadata.json","sizeBytes":1377,"isText":true},{"path":"references/official-sources.md","sizeBytes":1283,"isText":true},{"path":"references/workflow-and-output.md","sizeBytes":2836,"isText":true},{"path":"SKILL.md","sizeBytes":3902,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
