Each section states the rule to apply: decision criteria for deployment strategy, failure modes to catch in review, and verify steps. **Query the AWS APIs — never assume from IaC source or console screenshots** (state diverges from templates the moment a manual change is made). > **Load this skill when…** building or reviewing a CI/CD pipeline (CodePipeline, CodeBuild, CodeDeploy); authoring or debugging CloudFormation/CDK/SAM templates; designing deployment strategies (blue/green, canary, rolling); configuring observability stacks, automated remediation, or compliance-as-code on AWS. > **Not this skill:** threat-detection, IAM policy depth, or encryption → see `aws-security-specialty`; enterprise architecture trade-offs → see `aws-solutions-architect-professional`. > **Study resources and credential logistics:** [references/study-resources.md](references/study-resources.md). > **Verify steps** — use your project's MCP/automation, the AWS CLI (`aws`) or CloudShell, or the Console, in that order. --- ## Uncertainty & Escalation - **Always re-verify live — volatile facts:** service quotas (e.g., default CodePipeline pipelines per region `[volatile — verify live]`, CodeBuild concurrent builds per account `[volatile — verify live]`), EC2 instance type availability by region `[volatile — verify live]`, CloudWatch high-resolution metric pricing `
