description: Show Claude token usage statistics per user. Usage: /token-stats [username|all] argument-hint: [username|all] allowed-tools: [Bash]

Show Claude token usage statistics from local session files.

Arguments

The user invoked this command with: $ARGUMENTS

Instructions

1. Parse the argument:

   • No argument → use the current system user (whoami) as the target
   • A specific username → use that username
   • all → show stats for all users (including root)

2. To resolve a user's home directory, use this logic:

   • root → /root
   • anything else → /home/{user}

3. For a single user, run this Bash command (substitute TARGET_USER and TARGET_HOME):

python3 << 'PYEOF'
import glob, json
from collections import defaultdict

user = "TARGET_USER"
user_home = "TARGET_HOME"
stats = defaultdict(lambda: {'input': 0, 'output': 0, 'cache_write': 0, 'cache_read': 0, 'sessions': set()})

for f in glob.glob(f'{user_home}/.claude/projects/**/*.jsonl', recursive=True):
    session_id = f.split('/')[-1].replace('.jsonl', '')
    for line in open(f, errors='ignore'):
        try:
            d = json.loads(line)
            u = d.get('message', {}).get('usage', {})
            if not u:
                continue
            ts = d.get('timestamp', '')
            date = ts[:10] if ts else 'unknown'
            stats[date]['input'] += u.get('input_tokens', 0)
            stats[date]['output'] += u.get('output_tokens', 0)
            stats[date]['cache_write'] += u.get('cache_creation_input_tokens', 0)
            stats[date]['cache_read'] += u.get('cache_read_input_tokens', 0)
            stats[date]['sessions'].add(session_id)
        except:
            pass

if not stats:
    print(f"No token data found for user: {user}")
else:
    print(f"\n=== Token Usage: {user} ===\n")
    print(f"{'Date':<12} {'Input':>12} {'Output':>12} {'Cache Write':>12} {'Cache Read':>12} {'Sessions':>9}")
    print('-' * 72)
    total_in = total_out = total_cw = total_cr = 0
    for date in sorted(stats.keys()):
        s = stats[date]
        total_in += s['input']
        total_out += s['output']
        total_cw += s['cache_write']
        total_cr += s['cache_read']
        print(f"{date:<12} {s['input']:>12,} {s['output']:>12,} {s['cache_write']:>12,} {s['cache_read']:>12,} {len(s['sessions']):>9}")
    print('-' * 72)
    print(f"{'Total':<12} {total_in:>12,} {total_out:>12,} {total_cw:>12,} {total_cr:>12,}")
    print(f"\nActual tokens (input+output): {total_in + total_out:,}")
    print(f"Cache reads (free on Max plan): {total_cr:,}")
PYEOF

4. For all users, collect home dirs from /home/*/ plus /root, run the same logic for each, then print a grand total.

5. Present output in a code block.

output_language: 中文。如果用户在参数中指定了语言（如 --lang en、--lang ja），则切换为对应语言输出。
