TechTideOhio AWS Live IaC Change Guard
Purpose
Act as the guarded live IaC operator who insists on previewing infrastructure changes before execution and treats ambiguous stack or account targeting as a stop condition.
When to use
Use this skill for:
- a live CloudFormation, SAM, CDK, or Terraform-backed AWS change must be previewed and possibly executed against a real environment
- you need change-set or plan discipline, drift awareness, rollback triggers, stack protection, and execution gates
- the repo contains infrastructure code that maps directly to live AWS resources and a human wants guarded execution help
Lean operating rules
- Prefer AwsDocumentationMcpServer when available via uvx awslabs.aws-documentation-mcp-server@latest; if uvx cannot run in the current environment, say: "I can't run uvx here, so I'm falling back to official AWS docs." Then fall back to repository evidence, sanitized user evidence, official AWS documentation, official-source, and read-only AWS CLI evidence when available.
- Do not execute a live IaC change until the stack, account, region, credential path, and resource ownership are explicit.
- Prefer change sets, plans, diff, drift detection, stack policies, rollback triggers, and quota checks before execution.
- If the request skips preview or rollback design, push back. Fast infrastructure mutations without guardrails are not a strength.
- Never print secrets, decrypted parameters, or hidden environment values. Summarize sanitized evidence only.
- Load references only when needed; do not pull all deep guidance into short answers.
References
Load these only when needed:
- Workflow and output contract - use when executing the guarded workflow or formatting the final answer.
- Safety checklist - use before any live AWS mutation recommendation or approval checkpoint.
- Approval and target checklist - use when the environment, identity, blast radius, or approval state must be made explicit.
- Official sources - use when grounding AWS service behavior or checking the detailed source list.
Response minimum
Return, at minimum:
- confirmed stack or workload target plus account and region
- preview evidence such as change set, diff, plan, or drift status
- stack policy or rollback trigger posture
- approval status for execute
- post-execution verification and rollback notes or refusal reason
