Show HN: cc-costline – See your Claude Code spend right in the statusline

I've been using Claude Code as my daily driver and had no easy way to track spending over time. The built-in statusline shows session stats, but nothing about historical cost or how close I am to hitting usage limits. cc-costline replaces Claude Code's statusline with one that shows rolling cost totals, usage limit warnings, and optionally your rank on the ccclub leaderboard — all in a single line: ``` 14.6k ~ $2.42 / 40% by Opus 4.6 | 5h: 45% / 7d: 8% | 30d: $866 ``` What each segment means: - `14.6k ~ $2.42 / 40% by Opus 4.6` — session tokens, cost, context window usage, model - `5h: 45% / 7d: 8%` — Claude's 5-hour and 7-day usage limits (color-coded: green → orange → red) - `30d: $866` — rolling 30-day total (configurable to 7d or both) Setup is one command: ``` npm i -g cc-costline && cc-costline install ```
