ClaudeExtensions

A collection of hooks and extensions for Claude Code.

Hooks

hooks/statusline.sh

A StatusLine hook that displays real-time session info in your terminal status bar:

• Model shortname (op = Opus, so = Sonnet, ha = Haiku)
• Cost accumulated in the current session ($0.03)
• Context window usage with a color-coded progress bar (green/yellow/red) and token count
• Git branch with a * suffix if the working tree is dirty

Example output:

[so] $0.04 | ████░░░░░░ 42.3% (85K/200K) | main*

Installation

Requirements

• Claude Code installed
• Node.js (the hook runs via node)

via npm (recommended)

npm install -g @prafulsrivastava/claude-statusline

The postinstall script automatically copies the hook to ~/.claude/hooks/statusline.js and updates ~/.claude/settings.json with the required config. Just restart Claude Code after installing.

Manual install

1. Copy the hook to your Claude hooks directory:

   macOS / Linux

   mkdir -p ~/.claude/hooks
   curl -o ~/.claude/hooks/statusline.js \
     https://raw.githubusercontent.com/PrafulSrivastava/ClaudeExtensions/main/hooks/statusline.sh
   chmod +x ~/.claude/hooks/statusline.js

   Windows (PowerShell)

   New-Item -ItemType Directory -Force "$env:USERPROFILE\.claude\hooks"
   Invoke-WebRequest `
     -Uri "https://raw.githubusercontent.com/PrafulSrivastava/ClaudeExtensions/main/hooks/statusline.sh" `
     -OutFile "$env:USERPROFILE\.claude\hooks\statusline.js"

2. Register the hook in your Claude Code settings (~/.claude/settings.json):

   {
     "statusLine": {
       "type": "command",
       "command": "node ~/.claude/hooks/statusline.js"
     }
   }

   On Windows use node %USERPROFILE%\.claude\hooks\statusline.js for the command.

3. Start or restart Claude Code — the status line will appear automatically.
