Context Engineering vs. Prompt Engineering: What's the Difference?

Prompt engineering is a skill. Context engineering is a system. Here's the 60-second explanation of why the difference matters at enterprise scale and why tools like Anthropic Skills, OpenSpec, and GitHub Spec Kit are the local optimization trap. Context Engineering Patterns. We define both terms, name the spec-driven tools that solve context engineering at the repo level, and show why real systemic context engineering ADRs encoded, code maps queryable, decades of legacy code in Java, .NET, Python, even ABAP all grounded is the layer enterprises actually need.

The other is a system. What you'll learn - What prompt engineering actually is and what it isn't - Why "context engineering" doesn't just mean RAG - Why Anthropic Skills, OpenSpec, and GitHub Spec Kit are the local optimization trap - How ADRs, code maps, and grounded legacy code form the systemic layer - Why enterprises need the systemic layer above their dev tools Why this matters at enterprise scale Spec-driven tools work for one repo, one developer, one greenfield project. When you scale across teams, departments, legacy systems, compliance regimes, and decades of institutional knowledge, spec-driven approaches create silos. In LEAN terms: classic muda. OutcomeOps eliminates this waste value stream flows via reusable context; working software is grounded in codified intent.
