Claude Code Statusline

Install and configure a custom Claude Code status line showing real-time token usage, context window percentage, git branch, and color-coded warnings. Use when the user asks to "install statusline", "setup statusline", "configure statusline", "setup status line", "install status bar", "show token usage", "context window display", "statusline colors", "statusline thresholds", or wants to customize their Claude Code status bar display.

Install a security-hardened status line for Claude Code CLI that displays:

user@host:dir (branch) | Model | In:8.5K Out:1.2K Cache:7K [23%]

Prerequisites

• Python 3 (standard library only, no pip dependencies)
• git (optional, for branch display)

Script

scripts/statusline_installer.py -- Python 3, standard library only.

# Install with defaults
python3 scripts/statusline_installer.py install

# Install with custom thresholds
python3 scripts/statusline_installer.py install --threshold-yellow 30 --threshold-orange 50 --threshold-red 70

# Install with combined token display
python3 scripts/statusline_installer.py install --token-display combined

# Check installation
python3 scripts/statusline_installer.py status

# Update config
python3 scripts/statusline_installer.py configure --threshold-red 80 --color-green cyan

# Remove
python3 scripts/statusline_installer.py uninstall [--remove-config]

How It Works

1. install -- Copies statusline.py to ~/.claude/scripts/, creates config at ~/.claude/statusline.config (perms 600), updates ~/.claude/settings.local.json with python3 ~/.claude/scripts/statusline.py command.

2. status -- JSON output: script installed, config state, settings configured, git availability.

3. configure -- Update thresholds (--threshold-yellow/orange/red), colors (--color-green/yellow/orange/red), display mode (--token-display separate|combined). Validates threshold ordering.

4. uninstall -- Removes script, reverts settings. --remove-config also deletes config file.

Configuration

Config file: ~/.claude/statusline.config

Option	Default	Values
TOKEN_DISPLAY	separate	separate (In/Out/Cache), combined (total)
THRESHOLD_YELLOW	40	0-100
THRESHOLD_ORANGE	50	0-100
