🤔 Why Zero Agent?

Stop wasting money, tokens and hitting limits:

• ❌ Subscription quota expires unused every month
• ❌ Rate limits stop you mid-coding
• ❌ Tool outputs (git diff, grep, ls...) burn tokens fast
• ❌ Expensive APIs ($20-50/month per provider)

Zero Agent solves this:

• ✅ RTK Token Saver - Auto-compress tool_result, save 20-40% tokens
• ✅ Maximize subscriptions - Track quota, use every bit before reset
• ✅ Auto fallback - Subscription → Cheap → Free, zero downtime
• ✅ Multi-account - Round-robin between accounts per provider
• ✅ Universal - Works with any OpenAI/Claude-compatible CLI
