I built this after noticing a $65 charge for what felt like a $10 session. Turns out, context compaction was hiding 80% of my token usage. Real cost, no visibility.
claudetop is a status line for Claude Code that shows your burn rate, cache efficiency, model cost comparison, and smart alerts (like "TRY /fast" when Opus is overkill for the task). Plugin system for extensibility — Spotify, CI status, calendar, etc.
Single bash script, zero dependencies beyond jq. One-command install.
