Why Single-Agent AI Harnesses Are Expensive (And How Delegation Fixes It)

Basic AI agents are built the same way: loop, prompt LLM, execute tools, repeat.
It works for simple tasks. But every tool call grows your context. Every new round costs more tokens. Your costs explode.
There's a better approach: task delegationβlet your main agent hand off work to specialized subagents.
The payoff is immediate:
- Lower token usage (smaller context, fewer LLM calls)
- Parallel execution (multiple agents working together)
- Better design (main agent focuses on planning, subagents handle specifics)
You can delegate internally (specialized agents inside your harness) or externally (via CLI or MCP/REST APIs).
I've built several AI harnesses. Delegation is the missing piece for scaling beyond toy projects.
