LLM API Cost Optimization · 6 Must-Have Skills From Runaway Bills to Real Governance
Runaway loops, duplicate calls, premium-model-everywhere — the three classic money pits, each with a fix

If API bills dominate your month, read these three honest observations first
A friend's AI app went live and burned an extra $400 in three days. One endpoint failure without a timeout made the program fire 100K requests before anyone noticed. 90% of indie developers never see these silent bill-doublers coming.

Back on the Claude API, deep usage easily costs several dollars a day. The fix was finally mastering caching — most people ignore the difference between 5-minute and 1-hour cache tiers, and measured savings cut costs by 50-60%.

Agent tasks evolved from single Q&A to hours-long tool chains, consuming dozens of times the tokens of traditional usage. Cheap providers got overwhelmed by demand and price hikes are now an industry trend — spend discipline pays.

FAQ
Q: Do cost-optimization skills hurt model quality?
A: No. These skills never touch the model itself — they optimize how you call it: monitoring usage, reusing caches, routing simple tasks to cheaper models. Complex tasks still reach premium models, so quality holds while the bill shrinks.
Q: How are tokens actually priced? How much will my project burn?
A: Rough math: one CJK character is about 1 token and a line of code runs 10-30 tokens; a mid-sized typed frontend project can reach 500K-1.5M tokens. Use a skill like usage-costs to query today's, this week's and per-model costs instead of guessing.
Q: How much can prompt caching save and how do I use it?
A: Cache hits bill input at a steep discount, so the more repeated prefixes you have, the more you save. claude-api-cost-optimizer ships a combined strategy of model selection, prompt caching, batching and cost tracking you can apply directly.
Q: What does model tiering and routing mean?
A: Assign models by task complexity: about 95% of routine Q&A and status checks go to cheap models while 5% of critical decisions and hard debugging go to flagship ones. model-router-premium routes automatically based on configured cost and complexity — no manual switching.
Q: How do I stop an agent runaway loop from torching the budget?
A: llm-cost-watchdog monitors costs in real time, detects runaway loops, enforces budgets, and reports usage across multiple providers and models — the last gate before your API goes live.
Q: Where do I install these skills?
A: Every skill card has a Copy command button — copy it and hand it to your agent to install. You can also click a card title to jump to its meyo.life skill page for details.
