obs-cost

Show AI coding cost and token usage. Use this skill whenever the user asks how much they spent, wants a cost breakdown by provider or model, asks about token consumption, wants to compare Claude vs Gemini costs, or mentions anything about budget, spend, billing, or usage dollars. Supports time ranges like today, yesterday, week, 24h. Even if the user just says "how much did I spend" or "cost report" — use this skill.
