Build a Two-Row Status Line for Claude Code

Row 1 — where am I?

~/dev/aimhuge (main) [opus] — the working directory, the git branch, and the model I'm on. Then the session's name (here, the task in flight: "Invert menu order in projects page"). One glance answers "which repo, which branch, which model, doing what."

Row 2 — how much runway?

ctx:65% — how much of the context window is left. Every percentage on this line is a burndown: it starts at 100% and counts down, green while there's room and shading to red as it runs out. When ctx gets low — around 20% on Opus's 1M-token window — a compaction is coming, so it's my cue to wrap up a thread or hand off.

tok:351.5k — total tokens used this session.

+1681/−676 — lines added and removed this session. This is the one I love: it's how much work actually landed — real code churn, not just tokens spent. And the deletions aren't waste — lines removed is often the sign of a good refactor: cutting cruft, collapsing duplication, simplifying. A session that's net-negative can be the most valuable kind.

5hr:95% reset 10pm · 7d:95% — the part I care about most: how much of my 5-hour and weekly rate-limit budget is left, and when the window resets. Green means plenty; it shades to red as I burn it down. No more surprise "you've hit your limit" mid-task.

Row 3 — what can it do without asking?

▸▸ bypass permissions on (shift+tab to cycle) — the current permission mode. That row is built into Claude Code, not part of the status line, but it's worth keeping visible so "why didn't it ask me?" is never a mystery.

Design decisions worth stealing

Install it by hand

Requirements: jq and git on your PATH (the script degrades gracefully without git). Three steps:

1. Save the script below to ~/.claude/statusline-command.sh (or download it straight from GitHub: statusline-command.sh, part of the statusline-setup skill).

#!/bin/sh
# Claude Code status line
# Row 1: ~/dir (branch) [model] session-name
# Row 2: ctx:N% tok:Nk +N/-N  ║  5hr:N% reset Xam · 7d:N% reset day Xpm

2. Make it executable:

chmod +x ~/.claude/statusline-command.sh

3. Point Claude Code at it in ~/.claude/settings.json:

// ~/.claude/settings.json
{
  "statusLine": {
    "type": "command",
    "command": "bash ~/.claude/statusline-command.sh"
  }
}

Restart Claude Code (or start a new session) and the two rows show up. It's the cockpit I didn't know I needed.
