Everyone is talking about token spend, but not what we actually spend tokens on. I’ve always found it interesting to track my time across different tasks to challenge whether I was working on the right things.

Nowadays, I spend around 95% of my day in the Claude desktop app, so “where did my time/tokens go?” basically means “what did I do in Claude?”*

Turns out it’s all already on your disk. Every Claude Code / Cowork session is a JSONL transcript with per-message usage blocks: input, output, cache creation, cache read, and timestamps.

Run it from the terminal:

  curl -fsSL 'https://gist.githubusercontent.com/danmeier2/064f7db8c0867dd6331007ba43f0e6fe/raw/claude-token-analyzer.py' | python3 -

Run the snipped to get an overview of what you did and when based on your Cowork and Claude Code history. Example output:

*ccusage doesn’t see my Claude Code sessions because they’re stored in ~/Library/Application Support/Claude/local-agent-mode-sessions/.
