CostLens - Token Cost Monitor

Stop the "token meltdown" before it happens.

The Problem

OpenClaw can become a token furnace:

• Multi-step tasks consume tokens rapidly
• Long contexts multiply costs
• Concurrent execution compounds spending
• No visibility until the bill arrives

The Solution

CostLens provides real-time cost visibility:

Cost Optimization Tips

1. Model Selection - Use cheaper models for simple tasks
2. Context Trimming - Reduce token context when possible
3. Caching - Cache repeated queries
4. Batching - Group related operations
