Monitors and calculates real-time API token usage and USD costs for specific Claude Code session operations.
The API Cost Tracker skill provides developers with precise visibility into their Anthropic API spend by measuring token consumption during specific tasks. By parsing session JSONL files, it tracks input, output, and cache tokens—including cache hits and ephemeral writes—and applies up-to-date pricing to generate detailed reports. This skill is essential for teams managing budgets or developers seeking to optimize prompt efficiency by identifying expensive operations within their automated coding workflows.
