AI Agent评估框架膨胀问题引关注

Highly-recommended read.

Aligns with what I see in my own harness:

> Pi harness got the same success rate as harnesses from the LLM vendors with Opus and GPT, but at 2x less cost

> GLM 5.2 was a major step forward in open-source coding agent performance

The harness bloat/rot is real!
