cc-tempo

A Claude Code statusline that shows not just how much you've used, but how fast you're working.

Why cc-tempo

Other statuslines show how much. cc-tempo also shows how fast:

• ⏱ Active work time — real wall-clock work time (parsed from transcript), not inflated api_duration_ms
• [1.8×] Speedup ratio — shown when SubAgents give you ≥ 1.2× parallel gain
• /clear-resilient timer — persists inside the same claude process; a new claude invocation resets cleanly
• Quality sparkline ▁▂▃▅▆▇█ ↑ — code-change velocity over the last 8 ticks, with trend arrow
• Multi-instance 2 active — concurrent claude sessions on the same project directory

Layout

Line	When it renders	Contents
1	always	tokens · $cost · context bar · cache% · ⏱ time · [speedup]
2	inside a git repo	branch · N active · diff · lines/$ · quality sparkline
3	when rate_limits is in stdin	5h gauge · 7d gauge · ↻ countdowns
