List S3 Buckets

What I Do

This skill provides a script to list all S3 buckets in your AWS account using the aws s3api list-buckets command. Results are returned in TOON format for efficient token usage.

Configuration

AWS requires SSO authentication to access S3 buckets. If the aws command returns an error that no matching credentials were found or no access to resources, return the following:

Authentication Failure: AWS SSO has not been authenticated.
Please follow your AWS SSO login procedure and then try again.

Workflow

Use the list_buckets.sh script to list all S3 buckets in your AWS account.
