S3 Resiliency Review Skill

\n

A skill for AWS DevOps Agent that performs a structured, read-only resiliency,\nsecurity, and data protection review of Amazon S3 buckets and produces a rated\nreport with prioritized findings and remediation guidance.

\n

What it does

\n

Given one or more S3 bucket names, the skill collects each bucket's configuration\nusing read-only control-plane API calls and evaluates it across nine dimensions:

\n
    \n
  1. Versioning — protection against overwrites and deletes
    2. \n
  2. Replication — cross-region / cross-account redundancy (four-quadrant risk model)
    3. \n
  3. Object Lock — immutability / WORM protection
    4. \n
  4. Bucket policy — defensive Deny statements and transport security
    5. \n
  5. Block Public Access — bucket- and account-level, cross-referenced with ACLs and policy
    6. \n
  6. Default encryption — SSE-S3 / SSE-KMS / DSSE-KMS and Bucket Key
    7. \n
  7. Ownership controls — ACL posture and BucketOwnerEnforced migration
    8. \n
  8. Server access logging — logging or CloudTrail S3 data events for audit trail
    9. \n
  9. Static website hosting — public-by-design exposure checks
    10. \n
\n

Each bucket receives a Resiliency Rating (High / Medium / Low / Indeterminate)\nwith per-dimension findings. Reviews are routed automatically:

\n\n

Prerequisites

\n

The DevOps Agent role must have read-only permissions for the review to\nproduce complete results. These are IAM action names (which differ from the API\ncall names for some S3 operations):

\n
s3:ListBucket\ns3:ListAllMyBuckets\ns3:GetBucketVersioning\ns3:GetReplicationConfiguration\ns3:GetBucketObjectLockConfiguration\ns3:GetBucketPolicy\ns3:GetBucketPublicAccessBlock\ns3:GetAccountPublicAccessBlock\ns3:GetEncryptionConfiguration\ns3:GetBucketOwnershipControls\ns3:GetBucketAcl\ns3:GetBucketLogging\ns3:GetBucketWebsite\ns3:GetBucketCORS\ns3:GetBucketLocation\ncloudtrail:DescribeTrails\ncloudtrail:GetEventSelectors\n
\n

(sts:GetCallerIdentity is also used to resolve the account ID; it requires no\nIAM permission.)

\n

Most of these are covered by AIDevOpsAgentAccessPolicy. If a check lacks\npermission, the skill reports it as \"Unable to verify — access denied\" and caps the\nResiliency Rating at Medium rather than guessing the configuration.

\n

The skill never reads object data (GetObject) and never performs any\nwrite, create, update, or delete operation.

\n

How to use it with DevOps Agent

\n

Works with the Chat and Investigations / Incident RCA subagents. Describe\nthe task in natural language — you do not need to name the skill:

\n\n

The agent gathers configuration via its use_aws tool under the assumed role in the\ntarget account, applies the finding logic, and returns a Markdown report artifact.

\n

Agent Types

\n

This skill is used by the following agent types (selected in the Operator Web App\nat upload time):

\n\n

Select Generic instead if you want the skill available to all agent types.

\n

Uploading to AWS DevOps Agent

\n

To deploy this skill to your Agent Space, you can use any of three ways:

\n

Option A: Import from GitHub (recommended)

\n

If you have a GitHub connection configured in your Agent Space, you can import this skill directly from the repository. In the DevOps Agent web app, go to Settings → Add Skill → Import from repository, then point to the skills/storage-s3-resiliency-expertise directory. See Importing a skill from a repository for full instructions.

\n
\n

Note: You cannot connect the aws GitHub organization directly because the GitHub connection setup requires admin rights on the organization. Instead, connect your personal GitHub account and select any repository from it during the connection setup. Once a GitHub connection is established, you can import skills from any public repository, including this one, even if it wasn't selected during the connection setup.

\n
\n

Option B: Upload as a zip file

\n
    \n

  1. Zip the storage-s3-resiliency-expertise/ directory (only including allowed extensions):

    \n
    cd skills\nzip -r storage-s3-resiliency-expertise.zip storage-s3-resiliency-expertise/ -i '*.md' '*.txt' '*.json' '*.yaml' '*.yml' '*.xml' '*.csv' '*.tsv' '*.html' '*.htm' '*.png' '*.jpg' '*.jpeg' '*.gif' '*.svg' '*.webp' '*.pdf' -x '*/.claude/*' '*/scripts/*' '*/README.md' '*/.skilleval.yaml' '*/.skilleval.yml' '*/CHANGELOG.md' '*/evals/*'\n
    \n
    2. \n

  2. In the AWS DevOps Agent web app, navigate to the Skills page.

    \n
    3. \n

  3. Click Add skill → Upload skill.

    \n
    4. \n

  4. Drag and drop the storage-s3-resiliency-expertise.zip file (max 6 MB).

    \n
    5. \n

  5. Select the agent types: Chat tasks, Evaluation, and Incident RCA.

    \n
    6. \n

  6. Click Upload.

    \n
    7. \n
\n

Option C: Upload via the Asset API

\n

Use the AWS DevOps Agent Asset API to programmatically manage skills — useful for CI/CD pipelines or automation workflows. Assign the skill to the CHAT, EVALUATION, and INCIDENT_RCA agent types. See Managing a skill end-to-end for the full API workflow.

\n

For more details, see Uploading a skill in the AWS DevOps Agent User Guide.
