The Token Waste Problem: Why your AI Agents shouldn't evaluate permissions

The Token Waste Problem: Why your AI Agents shouldn't evaluate permissions

Short summary

Multi-agent systems waste tokens by asking LLMs to evaluate deterministic tasks like permissions. Delegate policy enforcement to code; reserve AI reasoning for actual cognitive problems. This improves cost, reliability, and follows fundamental software engineering principles.

  • LLMs are probabilistic and expensive; don't use them for deterministic tasks
  • Policy checks, routing, and validation belong in code, not in prompts
  • Reserve LLM reasoning for actual cognitive work

Generated with AI, which can make mistakes.
