The Model Usage skill provides deep visibility into your AI spending by aggregating and summarizing local cost data from the CodexBar CLI. It allows users to query cost breakdowns for both Codex and Claude providers, supporting both 'current model' snapshots and full historical breakdowns. This skill is essential for developers and teams looking to optimize their LLM budgets, identify high-cost models, and maintain scriptable control over their AI consumption telemetry through easy JSON exports and CLI integration.
