# Claude Code Status Line

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

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 |

| `THRESHOLD_RED` | `70` | 0-100 |

| `COLOR_*` | standard ANSI | Color name or ANSI code |

Available colors: green, yellow, orange, red, blue, cyan, magenta, purple, white, pink, bright-green, bright-yellow, bright-red, bright-blue, bright-cyan, bright-magenta.

After Install

Restart Claude Code (`exit` then `claude`) to activate.
