Claude Code Status Line

Example: [Opus 4.6 (1M context)] Context: 0% (↑339 ↓7.9k) | $0.53

1. Place the above script in ~/.claude/statusline.sh

2. Edit ~/.claude/settings.json to include a new key:

   "statusLine": {
     "type": "command",
     "command": "~/.claude/statusline.sh"
   }
   

statusline.sh

#!/bin/bash
input=$(cat)

MODEL=$(echo "$input" | jq -r '.model.display_name')
INPUT_TOKENS=$(echo "$input" | jq -r '.context_window.total_input_tokens')
OUTPUT_TOKENS=$(echo "$input" | jq -r '.context_window.total_output_tokens')
CONTEXT_SIZE=$(echo "$input" | jq -r '.context_window.context_window_size')
COST=$(echo "$input" | jq -r '.cost.total_cost_usd')

TOTAL_TOKENS=$((INPUT_TOKENS + OUTPUT_TOKENS))
PERCENT_USED=$((TOTAL_TOKENS * 100 / CONTEXT_SIZE))

format_tokens() {
    local n=$1
    if [ "$n" -lt 1000 ]; then
        printf "%d" "$n"
    else
        local tenths=$((n / 100))
        printf "%d.%dk" "$((tenths / 10))" "$((tenths % 10))"
    fi
}

IN_FMT=$(format_tokens "$INPUT_TOKENS")
OUT_FMT=$(format_tokens "$OUTPUT_TOKENS")

printf "[%s] Context: %d%% (↑%s ↓%s) | \$%.2f" "$MODEL" "$PERCENT_USED" "$IN_FMT" "$OUT_FMT" "$COST"
