Key Takeaways

  • 1.Assembly is the ordered packing of sections into one window.
  • 2.Typical order: system, tool schemas, retrieved facts, memory, recent turns, live user.
  • 3.Never drop the live user turn to save tokens.
  • 4.Each section should have a hard cap.
  • 5.Without an assembly plan, teams concatenate strings until the API errors.

Real Example

Scenario

Assembly: pack only what this turn needs.

What you would do

In Context Engineering, apply Context Assembly to this scenario: Assembly: pack only what this turn needs. Identify the inputs, run the technique, validate the output, and note one thing you would monitor in production.
