Queries a local SQLite database to show you how much you've spent on Claude Code sessions, broken down by project, tool, date, or session. Assumes you're already running a cost tracking hook that logs token usage to `~/.claude-cost-tracker/usage.db`. The queries are straightforward: today versus total, top projects by cost, seven-day trends, session drilldowns. It won't guess at pricing or make up data if the database is missing. Salvaged from a stale community PR, so it's narrow in scope but does one thing cleanly if you have the infrastructure in place.
