AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
This skill provides comprehensive domain expertise for managing Amazon Route 53 DNS configurations. It acts as a router to specific, self-contained procedures for tasks ranging from basic public DNS record creation to complex hybrid network resolution, traffic steering, and security-focused DNS Firewall management. It emphasizes best practices for IAM security, DNS transport encryption, and scalable configuration management across multi-account environments.
What it does
- Maps hostnames to IPs, AWS resources, or other hostnames via public DNS records.
- Implements traffic-steering policies like weighted routing and failover for disaster recovery.
- Configures health checks to monitor endpoint availability and trigger alerts.
- Secures VPC traffic by blocking malicious domains using DNS Firewall.
- Centralizes DNS configurations and security rules across multiple accounts using Route 53 Profiles or Firewall Manager.
- Enables hybrid network resolution and manages VPC Resolver configurations for Outposts.
When to use it
- When you need to point a domain or subdomain to an AWS resource or external IP.
- When implementing blue/green deployments or canary releases using weighted routing.
- When setting up high-availability architectures requiring cross-region failover.
- When you need to filter malicious DNS queries within a VPC.
- When managing DNS configurations at scale across an AWS Organization.
- When resolving private DNS queries between on-premises networks and AWS VPCs.
Advantages
- Provides structured, step-by-step procedures for complex DNS tasks.
- Includes critical security constraints for IAM and DNS transport.
- Offers clear decision frameworks for choosing between routing policies or centralization methods.
- Ensures consistent configuration by routing to specialized, self-contained reference files.
- Supports both sandboxed execution via AWS MCP and standard AWS CLI fallback.
Usage examples
- “How do I point my domain example.com to an S3 bucket?”
- The agent will guide you through the 'creating a public DNS record' procedure to map your domain to the S3 bucket endpoint.
- “I need to block known malicious domains for all my VPCs.”
- The agent will direct you to the 'centralizing DNS Firewall' procedure to deploy protection across your organization.
- “How can I fail over traffic between two regions?”
- The agent will provide the 'configuring failover routing' steps, including setting up the necessary health checks.
- “How do I resolve private DNS between my on-premises network and AWS?”
- The agent will walk you through the 'resolving private DNS for hybrid networks' procedure.

Amazon Route 53
Overview
Domain expertise for configuring Amazon Route 53 DNS across the public and private resolution paths: hosted zone records, traffic-steering routing policies, health checks, DNS Firewall, Route 53 Profiles, VPC Resolver (also known as Route 53 Resolver) for hybrid and Outposts networks, and Global Resolver.
This skill is a router. Each customer task maps to a procedure file under references/. Read the
matching reference in full before acting, then follow its constraints and steps. The reference
files are self-contained: each carries its own decision tables, constraints, procedure, and
troubleshooting.
Execute commands using the AWS MCP server when connected (sandboxed execution, audit logging,
observability). Fall back to the AWS CLI otherwise. All Route 53 Domains API calls are made in
us-east-1 regardless of where the customer works.
Which Route 53 task do you need?
| Goal | Reference |
|---|---|
| Point a hostname or zone apex at an IP, AWS resource, or hostname | creating a public DNS record |
| Split traffic across endpoints in a ratio (blue/green, canary, A/B) | splitting traffic with weighted routing |
| Fail over between two Regions for disaster recovery | configuring failover routing |
| Monitor whether an endpoint is up and get alerted | setting up a health check |
| Block malicious domains for a VPC at the resolver | blocking malicious domains |
| Work out which DNS Firewall rule wins for a domain across multiple rule groups | identifying the effective DNS Firewall rule |
| Apply one DNS config across many VPCs and accounts | configuring Route 53 Profiles |
| Fan DNS Firewall out across many accounts org-wide | centralizing DNS Firewall with Profiles |
| Resolve private DNS both ways across a hybrid network | resolving private DNS for hybrid networks |
| Run VPC Resolver locally on an AWS Outposts rack | running VPC Resolver on Outposts |
| Give on-premises and remote clients one anycast DNS endpoint | setting up Global Resolver |
Routing notes
Records vs routing policies. A plain hostname-to-target mapping is the public DNS record task. Splitting or steering traffic (weighted, failover) is a separate routing-policy task with its own reference. Start from the customer's intent, not the record type.
Health checks vs failover. A health check monitors an endpoint and raises alarms. The failover routing policy decides where traffic goes when a check fails. They are two references and are often used together: set up the health check, then wire it into failover.
DNS Firewall for one VPC vs many accounts. Authoring rules for a VPC is the blocking reference. Fanning the same protection across accounts with Profiles and Firewall Manager is the centralizing reference.
DNS Firewall authoring vs diagnosis. Creating or changing rules is the blocking reference. Working out which rule already wins for a domain when several rule groups are associated (a read and diagnostic task) is the identifying-the-effective-rule reference.
Profiles, two entry points. General Profile setup (attach resources, share via RAM, cost and visibility tradeoffs) is the configuring-Profiles reference. Using Profiles specifically to scale DNS Firewall org-wide is the centralizing reference.
VPC Resolver, three contexts. In-Region hybrid resolution, the Outposts-local resolver, and the Global Resolver anycast endpoint are three separate references. Match the reference to where the resolver runs.
Cross-service work
Pointing a custom domain at a CloudFront distribution, or failing over between CloudFront distributions, is cross-service work spanning Route 53 and CloudFront. Use this skill for the Route 53 side of pure-Route 53 tasks only.
Security Considerations
These apply across the Route 53 tasks below; each reference repeats the ones load-bearing for its workflow.
You SHOULD use least-privilege IAM credentials provisioned through IAM roles (instance profiles, SSO/IAM Identity Center session credentials, or
aws sts assume-role) rather than long-lived IAM user access keys, and prefer read-only credentials for inspection steps.You SHOULD recommend encrypted DNS transport (DoT or DoH) over plaintext Do53 for resolver client populations, since Do53 exposes queried domain names to on-path observers.
You MUST scope resolver-endpoint security group rules on port 53 to the on-premises CIDR ranges or known DNS server IPs, never
0.0.0.0/0.You MUST encrypt query log and notification destinations at rest: KMS on CloudWatch Logs log groups, SSE-S3/SSE-KMS on S3 buckets, server-side encryption (SSE) on a Data Firehose stream, and SSE on SNS topics, because DNS query logs and health-check notifications can reveal infrastructure topology.
For Global Resolver, you MUST treat access-token
valuereturned at create time as a secret; store it in AWS Secrets Manager rather than in plaintext, and validate which client populations each DNS view authorizes.
