Function machine_spend 

pub fn machine_spend(
    homes: &HarnessHomes,
    since_ms: i64,
    now_ms: i64,
    harnesses: &[String],
    sort: &str,
    limit: Option<usize>,
) -> Value

Every Claude Code and Codex session on this machine with recorded use from since_ms to now, a subagent’s use on its parent. Sorted by sort: cost (the default) puts priced sessions first, most cost first, then the rest by tokens; tokens sorts all by tokens. harnesses limits the reading (empty: both); limit keeps the first rows.
