i think its the opposite. claude code apparently removed hundreds of lines of system prompt because its not relavent anymore with newer models.

also i think its hard to build general harnesses if they were trained on specific harness architecture.

Yes but Pi has had a minimal system prompt since inception. Skills and Pi extensions let you make a hyper specific harness for specific use cases. For general conversation, harnesses are overkill most times.

There’s evidence of harnesses making a smaller, weaker model perform better than SOTA and some benchmarks ban harnesses because it becomes too easy.
