Status Line Setup Skill

This skill provides guidance for configuring Claude Code's status line with customizable display options, progress bars, and cross-platform support.

When to Use This Skill

Invoke this skill when:

• Setting up a custom status line for Claude Code
• Configuring which elements to show/hide in the status line
• Adding a visual progress bar for context usage
• Setting up cross-platform status line scripts (bash/PowerShell)

Setup Workflow

Phase 1: Check Existing Configuration

1. Detect the operating system using Bash: uname -s (returns "Darwin" for macOS, "Linux" for Linux)
   • If command fails or returns "MINGW"/"MSYS"/"CYGWIN", assume Windows
2. Read the user's settings file:
   • Mac/Linux: ~/.claude/settings.json
   • Windows: C:/Users/USERNAME/.claude/settings.json (get USERNAME from environment)
3. Check if statusLine section already exists
4. If exists, ask user using AskUserQuestion:
   • Replace: Back up existing file and create new configuration
   • Cancel: Stop the setup process

Phase 2: Configuration Wizard

Use the AskUserQuestion tool to gather user preferences. Group questions logically:

Question 1: Context Information

• Show model name (default: yes)
• Show token count e.g. "50k/100k" (default: yes)
• Show progress bar (default: yes)

Question 2: Project Information

• Show current directory (default: yes)
• Show git branch (default: yes)

Question 3: Session Information

• Show session cost (default: no)
• Show session duration (default: yes)
• Show current time (default: yes)
• Show Claude Code version (default: yes)

Phase 3: Create Script File

Based on OS, create the appropriate script file:

Mac/Linux: ~/.claude/statusline.sh Windows: C:/Users/USERNAME/.claude/statusline.ps1

If script file already exists, back it up first with .backup extension.

Phase 4: Update Settings

Update the settings.json file with the statusLine configuration:

Mac/Linux:

{
  "statusLine": {
    "type": "command",
    "command": "/Users/USERNAME/.claude/statusline.sh",
    "padding": 0
  }
}

Windows:

{
  "statusLine": {
    "type": "command",
    "command": "powershell.exe -NoProfile -ExecutionPolicy Bypass -File C:/Users/USERNAME/.claude/statusline.ps1",
    "padding": 0
  }
}

Phase 5: Make Executable (Mac/Linux only)

Run chmod +x ~/.claude/statusline.sh to make the script executable.

Important Notes

• The scripts require jq to be installed on Mac/Linux for JSON parsing
• PowerShell scripts work on Windows PowerShell 5.1+ and PowerShell Core 7+
• Unicode progress bar characters (▓░) should work on modern terminals
• Colors use ANSI escape codes which work on most modern terminals
• Status line updates appear immediately after setup
