Context Engineering

Deciding what a model sees is a bigger lever than deciding how you ask. Budgets, retrieval, ordering and compaction, and how to tell whether your pipeline is helping.

Pathaxis · Original content

Written in house, from the work rather than from a syllabus. Every example is one we would use ourselves, and every quiz question explains why its answer is right.

What you’ll learn

  • Treat the context window as a budget with competing claims
  • Decide what deserves space and what does not
  • Account for position effects when ordering material
  • Compact history without losing what mattered
  • Recognise that tool definitions are context too
  • Evaluate a retrieval pipeline rather than trusting it

Before you start

  • · Generative AI Foundations and Prompt Engineering
  • · No coding required, though examples assume you are building something

Syllabus
