what’s actually in an agent & harness?  how do we engineer them?  what are coding agent products bundling into their harness to get good performance & UX?

seeing a lot of these questions so did a pass at re-distilling my mental model in this tweet response

the TLDR:
“””
Agent = model + prompts + skills/tools/MCP + subagent definitions + memory

Harness = execution loop + context management + permissions/resource policies 

Roughly, Harnesses define the runtime logic + everything they bundle/inject to make the execution work.  And today, harnesses are full on products —> they bundle more stuff in including agent content.

Final Sarah Paine lecture: Why Russia lost the Cold War.

To me, the most interesting question is not why the Soviet Union ultimately collapsed - it's how a brutal, centrally planned, stupendously inefficient, colonial land empire survived for so long.

I was surprised to learn about the central role that oil played in sustaining (and eventually dissolving) the Soviet Union.

By the 1950s, the Soviet system was in a crisis. Soviet growth rates had started to slow significantly as compared to the booming West. USSR's heavy-industry based economy was energy-starved. The 1953 CIA-backed coup in Iran blocked Soviet access to Iranian oil.

But in 1959, they discovered massive oil fields in Siberia. And of course the 1973 oil crisis multiplied the value of those exports. From 1973-1985, energy exports accounted for a shocking 80% of the USSR's hard currency earnings, which they needed to buy all the things central planning couldn't produce effectively - from grain to advanced technology - and support the many million strong Red army occupying Eastern Europe.

And then oil prices plummeted (69% in just 8 months following 1985). USSR government deficit went from around 2% of GDP in 1985 to 20% in 1991.

Anyways, all this to say that the discovery of massive oil fields in Siberia might have kept a floundering and obviously unworkable Communist system on life support for an extra 30 years. This way the USSR collapsed in 1991, and not 1961.
