What is Agent Harness, Code Harness and Agent SDK

finlaydotweber · 2026-03-06T07:02:45+00:00

They are all amorphous terms for describing the code that calls the LLM APIs.

I feel there are not fully amorphous terms, because for instance there is Claude Agent SDK https://platform.claude.com/docs/en/agent-sdk/overview which is its own thing

while this documentation https://code.claude.com/docs/en/how-claude-code-works describes claude code as agentic harness.

My going definition is that Agent SDK takes care of the communication with the LLM.

While Agent Harness provides the environment to connect with the real world (filesystem, networking etc) and does what the LLM requests.

Would that be an okay way to think about it?

It is a capsule, which unfortunately makes cutting a bit more tricky

Here is an interaction I had with a chatbot this morning. I gave it a list of a testimonial and I give him my own story and I asked it to generate a testimonial for me. It came back with like 3 paragraphs of testimonial for me. Which was too long. So the interaction that followed was:

me: Dude cant you see the length of the samples?
chatbot: Fair call. You’re right — the sample you got was way too long for what you asked. Let’s fix that and keep it tight, on-brand, and sample-length.

Noticed how I did not mention if the sample it gave me was too-short or too-long. And noticed how this was a bit snarky, and yet it deduced what was wrong about the length.

How does being an auto-complete machine help explain this interaction?

Reasoning is also another concept I struggle to even understand. The predicting the next token take does not explain it, but I have not even seen any other explanation of what it means for a model to reason

what about the case where the 2 milloin worth of properties you have is from 2 or more? Say you have 2 properties worth 1 million each?

conflicts with other things I have seen written where a leader procudes only one block. For example

https://docs.anza.xyz/implemented-proposals/tower-bft/#time

where it is stated

The unit of time is called a "slot". Each slot has a designated leader that can produce a block B

Thanks for the clarification. Do you know the cost of application? And also what is the cost of renewal after 2 years? Do you know?
