Harness Engineering for Self-Improvement

one form of very effective self-improvement that coding agents do all the time:

install or build stuff that they can then use

it changes the environment instead of the agent/harness but in a sense how separate is the agent from its environment and why do we apply this distinction re self-improvement?

animals and humans do the same thing and are great at it, without 'self-improvement' with emphasis on the 'self'

The quest for Torment Nexus continues

I've been working with self improvement harness a little bit and one thing i've come to conclusion is harness task fit. The learning can be significantly improved if we understand the behaviour of task and how it should be learned. I'm pretty sure a general solution will definitely exist which will do fine, but we are yet to see one.

They say engineering but it's more a soft science.
