How does it calculate token costs?

It uses a built-in model rate table to automatically calculate costs based on input, output, and cached tokens, but also allows for manual cost overrides.

What is the Token Cost Ledger?

It is a specialized Claude Code skill that logs and analyzes AI token usage to help developers manage and report their AI-related expenses as COGS.

Where is the cost data stored?

Usage data is stored locally in git-trackable JSONL files within your repository, allowing you to version control and audit your AI financial records.

Does it support feature-specific cost tracking?

Absolutely. You can tag every log entry with a specific feature ID to generate a report showing exactly how much it cost to build a particular part of your application.

Can I set a monthly AI budget?

Yes, you can define a monthly budget in your configuration file, and the skill will provide health checks and alerts based on your spending thresholds.
