exa-cost-tuning

The Exa Cost Tuning skill appears coherently scoped to its stated purpose of optimizing costs through tier selection, sampling, batching, caching, and budget alerts. There are no evident dangerous download/execute patterns or credential harvesting flows. Data flows are largely confined to billing data and standard alerting channels, which is appropriate for the described functionality. While some practical integration details (authentication, initialization, and data minimization) are not shown, these are not inherently malicious or unsafe and can be addressed in real deployments.
