What it does

Shieldadvanced is an agent skill from aws/agent-toolkit-for-aws, published by the product's own GitHub organization. Configures AWS Shield Advanced for enhanced Distributed Denial of Service (DDoS) protection: subscribing accounts and adding resource protections, enabling automatic application layer (layer 7) mitigation through AWS WAF, configuring health-based detection with Route 53 health checks, setting up Shield Response Team (SRT) access and proactive engagement, reviewing DDoS events and requesting cost protection credits, and aggregating resources into protection groups.

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `references/aggregating-resources-into-protection-groups.md`, `references/configuring-health-based-detection.md` and `references/deciding-between-shield-standard-and-advanced.md`).

It sits in DevOps & Cloud, covering Cloud networking. It works with Amazon Web Services. The repository describes itself as: Official, AWS-supported MCP servers, skills, and plugins to help AI agents build on AWS. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit bd49cc8. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • aws

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • docs.aws.amazon.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Shieldadvanced loads about 2.2k tokens when it runs, and up to ~24k if it reads all its reference files. Until then it costs about 255 tokens; SKILL.md has 999 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~255
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~24k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

AWS Shield Advanced

Overview

Domain expertise for configuring AWS Shield Advanced, the paid tier that adds enhanced Distributed Denial of Service (DDoS) protection, automatic application layer mitigation, attack visibility, expert support, and cost protection on top of the always-on AWS Shield Standard. Covers subscribing and protecting resources, automatic application layer mitigation, health-based detection, Shield Response Team (SRT) access and proactive engagement, event review and cost protection credits, and protection groups.

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. Shield Advanced is a global service: its control-plane API calls run in us-east-1, so pass --region us-east-1 on every aws shield command.

Routing notes

  • Decide before you subscribe. Shield Advanced is a paid subscription that auto-renews on a one-year commitment. Before subscribing, confirm the customer actually needs it: Shield Standard (free, always on) plus AWS WAF rate-based rules and the AWS WAF Anti-DDoS managed rule group (AWSManagedRulesAntiDDoSRuleSet) covers many layer 7 cases at lower cost. Route to the deciding reference first when the customer has not made that call; route to the waf skill for the WAF rules themselves.
  • Subscribe and protect comes first. A subscription protects nothing on its own; resources have to be added explicitly. Every other task here assumes the resource is already subscribed and protected. Run the subscribing reference before any of the others if the customer is starting from scratch.
  • Automatic mitigation vs health-based detection. These are different controls and customers conflate them. Automatic application layer mitigation deploys AWS WAF rules during a layer 7 attack. Health-based detection feeds a Route 53 health check into Shield Advanced's detection so it reacts sooner. A customer can run either, both, or neither. Pick the reference that matches what they actually want.
  • Health check is also an SRT prerequisite. Proactive engagement (SRT reaching out) requires a Route 53 health check on the protected resource. If the customer wants proactive engagement, configuring health-based detection is the groundwork. The SRT reference points back to the health-based detection reference for that step.
  • Protection groups are detection-only. A protection group changes how Shield Advanced detects across a set of resources. It does not apply shared mitigation; automatic mitigation still works per resource. Use the protection-groups reference for detection tuning, not as a mitigation control.
  • WAF rules, health checks, and org rollout live elsewhere. Authoring the AWS WAF rules, the rate-based rule, or the web ACL is the waf skill. Creating the Route 53 health check is the route53 skill. Rolling Shield Advanced across an organization with Firewall Manager is the firewallmanager skill. This skill wires Shield Advanced to those pieces; it does not build them. AWS WAF is not optional alongside Shield Advanced: you SHOULD recommend an AWS WAF web ACL on every internet-facing protected resource (CloudFront distributions and Application Load Balancers) as defense in depth — Shield Advanced and AWS WAF are complementary layer 3/4 and layer 7 controls, and the rate-based rule that AWS WAF provides is also what cost protection requires.

Logging and monitoring

Visibility into both configuration changes and attack activity matters for every task here.

  • You SHOULD recommend enabling AWS CloudTrail so all Shield Advanced API calls (subscription, protection, SRT, and protection-group changes) are logged for audit purposes.
  • You SHOULD recommend enabling SSE-KMS encryption on the CloudTrail log bucket and CloudWatch Logs log group, since CloudTrail records sensitive API metadata (caller identities, resource ARNs, parameters) that must be encrypted at rest.
  • You SHOULD recommend CloudWatch alarms on Shield Advanced metrics (for example DDoSDetected and DDoSAttackBitsPerSecond) so operations staff are alerted when an event is detected.
  • You SHOULD recommend encrypting any SNS topics used for those alarms with SSE-KMS, since the notifications carry sensitive event data.
  • You SHOULD recommend confirming that all SNS topic subscribers for Shield Advanced alarms are authorized personnel approved to receive sensitive DDoS event notifications.

Security considerations

Shield Advanced setup creates IAM trust relationships and exposes log data, so call out the risks and the controls that contain them.

  • SRT role is a third-party principal. Granting SRT access creates an IAM role that drt.shield.amazonaws.com assumes to act in the account. Scope its trust policy with an aws:SourceAccount condition equal to the account ID to prevent confused-deputy assumption, grant it only the actions it needs, and revoke it with disassociate-drt-role when no longer required.
  • Log buckets shared with the SRT can leak data. AWS WAF and access logs capture request URIs, headers, and client IPs. Confirm those buckets have server-side encryption and carry no clear-text PII or secrets before sharing them with the SRT.
  • Least privilege for the operator. Scope the caller's IAM permissions to the minimum each procedure needs rather than broad Shield or administrator access.
  • Audit trail. Keep AWS CloudTrail enabled and logging shield:* calls so every configuration change leaves a record.
