A statusline for Claude Code.

Usage against time

Context window

The bar turns yellow at 25% and red at 50%. The thresholds are lower than on the limit bars, because a full context window stops you at once. The bar fills in eighths of a character, so it moves before the number changes.

When a window resets

When a 5-hour window ends, both halves drop to zero and the countdown restarts at 5h0m. The top half stays green here, because usage trails the clock the whole time.

The Fable window

Fable has its own weekly quota. It refills only at the weekly reset, so the blue half tells you how long the wait is. It resets with the 7-day window, so it shows no ↻ of its own.

Claude Code does not send this value. The script reads it from ~/.claude.json and refreshes it from the API in the background, at most every ten minutes.

What is on the line

The context window, then the 5-hour, 7-day and Fable windows. Each one is a label, a bar and a number. Your folder, branch and model sit at the start of the line.

The agent panel

When subagents run, Claude Code lists them below the prompt. A second script, subagent-statusline.sh, gives each row its own context bar, with the same thresholds as Ctx. A red row returns a thin answer, and the bar tells you before the answer arrives.

The main line barely moves while they work: each agent burns its own window, and your context stays clean.
