/usage
Show token consumption and cost or limit information for the session.
/usage shows how many tokens this session has used, plus cost or limit information from your Anthropic account. Use it when a long investigation is eating context, or when you want to check remaining allowance before starting a large task.
Type /usage with no arguments. /cost is an alias for the same command.
Runs immediately
/usage runs even while Claude is mid-response. You do not have to wait for the current turn to finish.
For model, login, and other session settings, use /status.
