The Agent Skills Directory

[SAFE]: The skill provides practical instructions and scripts for data engineering cost optimization, including SQL queries for system analysis and Python scripts for cluster management. All behaviors are consistent with its stated purpose.
[SAFE]: Python scripts utilize standard, well-known libraries such as boto3, pendulum, and trino. Network operations via urllib.request are limited to the AWS Instance Metadata Service (IMDS) at 169.254.169.254, which is the standard method for EC2 instances to receive spot interruption notices.
[SAFE]: SQL queries for Trino, ClickHouse, and BigQuery target official system tables and information schemas (e.g., system.runtime.query_history, INFORMATION_SCHEMA.JOBS_BY_PROJECT) to provide visibility into compute and storage costs.
[SAFE]: No hardcoded credentials, malicious prompt injections, or obfuscated code were detected. Placeholders for variables like slack_webhook_url are used appropriately in infrastructure-as-code snippets.
[SAFE]: External tool recommendations, such as the goldilocks Helm chart from Fairwinds, point to reputable sources within the cloud-native ecosystem.
