658jjh/claude-usage-tracker ? reverse-engineered prompt

Build me a local first mac app that scans my machine for AI coding usage and shows me how much I’m spending on Claude and Codex across tools like Claude Code, Claude Desktop, Cursor, Windsurf, Cline, Roo Code, Aider, Continue, and OpenClaw.

I want it to automatically find the log files, calculate token usage and estimated costs from the model pricing, and then show everything in a clean dark dashboard. Include a simple way to switch between All, Claude, and Codex, plus charts for daily spend, project breakdowns, session history, and a heatmap of when I use it most. It should also let me filter by source, model, date range, and minimum cost, and I’d like a detail view for each session with token breakdown and a quick way to resume a session if possible.

Keep everything private and on my computer, no cloud or telemetry. If you need to look up current docs online, go ahead.
