# Harnesses as context delivery

## Quote

> **“Harnesses today are largely delivery mechanisms for good context engineering.”** — [[entity-vivek-trivedy|Vivek Trivedy]]

## Context

The author summarizes the primary role of modern agent [[concept-agent-harness|harnesses]] in relation to context windows. The harness's job is not to be smart — that is the model's job — but to **curate, compress, and route** information into and out of the limited context window.

This framing explains why the three anti-rot strategies — [[concept-compaction|compaction]], [[concept-tool-call-offloading|tool-call offloading]], [[concept-progressive-disclosure|progressive disclosure]] — are the dominant harness techniques of the current era. They are all about **delivering the right context at the right time**.

## Implication

When evaluating a harness, ask: *what context does this deliver, when, and how clean is it?* This is the working test for modern harness quality.
