Use this skill when a user wants to understand what traffic is going through an AWS NAT Gateway, why it takes that path, or how to reduce NAT Gateway cost - for example "why is my NAT Gateway bill so high", "what is going through my NAT Gateway", traffic leaving through NAT instead of over peering or a VPC endpoint, EKS, ECS, or other private-subnet workloads sending heavy AWS API, container image, or S3 traffic through NAT, S3 traffic still hitting NAT even though a Gateway Endpoint exists…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Overview This skill analyzes NAT Gateway traffic — *where it is actually going and why it takes that path* — to surface network architecture issues (endpoints that exist but aren't used, internal services talking over public IPs, unintended cross-region data paths) and the cost reduction that follows from fixing them. NAT Gateway bills on GB processed, and the flow log destination IP is the only reliable way to know whether that traffic is addressable (routable around NAT for free or near-free) or genuinely has to leave the VPC. It is **read-only**: it produces traffic categorization, endpoint-coverage findings, and read-only validation commands (`describe-*`, `get-*`, `list-*`) — never mutating actions. It does not modify route tables, create endpoints, or change peering. ## Verification & Anti-Hallucination Directives (Mandatory) …

How to install
mdr add aws/tools-for-devops-agent/aws-natgw-traffic-analysis@sha256:10b206529aa103aeThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
