# Vivek Trivedy

## Role in This Source

Vivek Trivedy is the **author** of *The Anatomy of an Agent Harness*, published on the [[entity-langchain|LangChain]] blog. He writes from a harness-engineering practitioner perspective and articulates the framing that has become widely cited: **Agent = Model + Harness**.

## Attributed Contributions

Quotes attributed to Vivek in this vault:

- [[quote-harness-definition]] — *“If you're not the model, you're the harness.”*
- [[quote-context-engineering]] — *“Harnesses today are largely delivery mechanisms for good context engineering.”*
- [[quote-intelligence-vs-usefulness]] — *“The model contains the intelligence and the harness is the system that makes that intelligence useful.”*

Claims attributed to Vivek:

- [[claim-agent-equation]] — The definitional decomposition of an agent into model and harness.
- [[claim-long-horizon-compounds]] — That long-horizon execution requires compounding primitives.
- [[claim-harness-overfitting]] — That post-training with a fixed harness causes tool-logic overfitting.

Framework attributed to Vivek:

- [[framework-harness-derivation]] — The working-backwards methodology for deriving harness features.

Contrarian positions advanced by Vivek:

- [[contrarian-harness-optimization]] — Native harnesses aren't always best.
- [[contrarian-harness-longevity]] — Harness engineering will survive model advancements.
