Claude Code Statusline

A fast, dependency-free Go binary that renders a rich statusline for Claude Code. Reimplemented from the original bash script by jezweb/claude-skills.

Why?

The original bash implementation spawns ~10 sequential git subprocesses and ~15 jq invocations per render. This Go rewrite:

• Single JSON parse instead of many jq calls
• 3 parallel git calls with 500ms timeout
• Locale-independent cost formatting (no printf "%.2f" locale bugs)
• Zero dependencies — stdlib only

Installation

Download the latest release:

curl -L https://github.com/strayer/claude-code-statusline/releases/latest/download/claude-statusline -o ~/.claude/claude-statusline && chmod +x ~/.claude/claude-statusline

Or build from source (requires Go):

CGO_ENABLED=0 go build -ldflags="-s -w" -trimpath -o claude-statusline
cp claude-statusline ~/.claude/claude-statusline

Then configure in ~/.claude/settings.json:

{
  "statusLine": {
    "type": "command",
    "command": "~/.claude/claude-statusline",
    "padding": 0
  }
}
