# Context Architecture

## Skill #6 of [[framework-7-ai-skills]] — the 'crowning skill'

Described by [[entity-nate-b-jones]] as the **'crowning skill'** and one of the hardest to execute.

**Context Architecture** is the ability to build systems that supply AI agents with exactly the right information, at exactly the right time, on demand.

## The Dewey Decimal analogy

From [[quote-dewey-decimal]]: *'In a sense, context architecture is like building the Dewey Decimal System for agents.'*

## What it requires

- Distinguishing between **persistent context** (data the agent always needs) and **per-session context** (data specific to the current run).
- Structuring company data — policies, SOPs, databases — so it is **easily searchable and traversable** by agents.
- Keeping out 'dirty' or polluting data that triggers [[concept-context-degradation]].

## Adjacent literature

The 'information domain' + observability stack pattern extends this with real-time metrics, intersecting with [[concept-token-economics]].
