Use this skill whenever the user asks about their Claude Code spend, cost, token usage, cache efficiency, sessions, or anything related to "what is Claude costing me". Triggers include "how much did I spend", "why did my bill go up", "what session was most expensive", "do I have cache problems", "show me my Claude Code usage", "any sessions waste a lot of cache", "spend by project", "spend this week / month / today". This skill calls the local `ccmeter` CLI which reads `~/.claude/projects/*.jsonl` with no network access, then narrates the result. Do NOT trigger for questions about API pricing in the abstract or unrelated billing topics — this is specifically for the user's own Claude Code session-log analysis.
