# Context Engineering

## Definition

**Context Engineering** is the shift from crafting isolated text instructions to *architecting the entire information state* an AI system operates within.

## Origins

The term was popularized heavily by [[entity-anthropic-d24]] in late 2025. [[entity-harrison-chase]], founder of LangChain, captured the industry mood in his Sequoia Capital interview — see [[quote-harrison-chase-context]] — saying it described what his company had been doing all along.

## What It Encompasses

- **RAG pipelines** (see [[prereq-rag-pipelines]]) for dynamic retrieval.
- **MCP servers** ([[entity-mcp]]) for vendor-agnostic data connections.
- Structuring organizational knowledge so agents can access it dynamically rather than being told everything inline.

## Why It Is Necessary But Not Sufficient

Context Engineering tells an agent **what it needs to know** to solve a problem. It does *not* tell the agent **why** it is solving the problem or how to weigh competing priorities. That gap is the entry point for [[concept-intent-engineering]].

Context Engineering is the second discipline in the three-stage progression: [[concept-prompt-engineering]] → Context Engineering → [[concept-intent-engineering]].

## Failure Mode

When organizations stop at Context Engineering, they often produce [[concept-shadow-agents]] — fragmented, team-by-team RAG and MCP deployments without unified governance. The fix is consolidating into a [[concept-unified-context-infrastructure]] (Layer 1 of the [[framework-intent-gap-layers]]).

## Enrichment Note

The enrichment overlay could not verify a specific 2025 Anthropic paper formalizing "Context Engineering" or the donation of MCP to the Linux Foundation; treat dates as speaker-stated rather than canonical.
