Cost Guardian
Use this skill whenever the user mentions cost, costs, pricing, budget, spending, token usage, API costs, Gemini costs, AI costs, model costs, Supabase costs, Vercel costs, infrastructure costs, billing, 'how much does this cost', 'my bill is too high', 'reduce costs', 'save money', 'cost optimization', token counting, rate limiting for cost, model routing, 'which model should I use', tiered models, usage tracking, usage dashboard, or ANY cost management task — even if they don't explicitly say 'cost'. Running 3 Gemini models + Supabase + Vercel + multiple services without cost controls is a ticking time bomb.
