Cost Tracking

Use this skill to analyze Claude Code cost and usage history from a local SQLite database. It is intended for users who already have a cost-tracking hook or plugin writing usage rows to ~/.claude-cost-tracker/usage.db.

When to Use

• The user asks "how much have I spent?", "what did this session cost?", or "what is my token usage?"
• The user mentions budgets, spending limits, overruns, or cost controls.
• The user wants a cost breakdown by project, tool, session, model, or date.
• The user wants to compare today against yesterday or inspect a recent trend.
• The user asks for a CSV export of recent usage records.
