The 'why is my bill high' skill: audits where spend goes across token categories (cache_read, cache_write, output, input) and per-session attribution. Invoke for questions like 'cost breakdown', 'which sessions are expensive', 'what's driving spend', or 'cold start costs'. Not for week-over-week trend lines (use hermit-evolution) or simple total-spend summaries.
