ASU: One CLI that shows how much of your agent subscription is left (chaosguru.substack.com)

A new CLI tool named ASU (Agent Subscription Usage) has been launched to simplify the way users monitor their usage across multiple AI services, such as Claude Code, Codex, and GitHub Copilot. Currently, each service utilizes different metrics for tracking usage—ranging from time windows to request counts—all culminating in a percentage of usage. ASU allows users to aggregate this information with a single command, providing clarity on remaining usage before limits reset, and enabling both humans and automated agents to understand their usage at a glance. The significance of ASU lies in addressing a notable gap in the user experience of managing AI service subscriptions. By streamlining usage tracking into one coherent interface, ASU enhances operational efficiency and helps prevent unexpected interruptions. It securely accesses usage metrics via existing credentials without modifying them and outputs user-friendly visualizations (like color-coded bars) or JSON for programmatic access. This tool not only aids individual users but could also enhance the planning and responsiveness of agents operating in environments that rely on time-sensitive AI operations. Overall, ASU is a practical solution that highlights the need for better user experience in the rapidly evolving landscape of AI services.
