Why this lesson is worth learning
This lesson is not assembled from random fragments. It is organized as official definition + product abstraction + executable practice.
Learning Objectives
Separate system rules, task state, and live evidence into different layers
Understand why giant prompts create maintenance cost and drift
Learn to diagnose context structure instead of endlessly adding instructions
Practice Task
Take a long prompt you wrote before, split it into fixed protocol, task state, and external evidence, then define how each layer gets updated.
Editorial Review
Reviewed · DepthPilot Editorial · 2026-03-08
The lesson is grounded in official prompt-engineering and context-window guidance.
It emphasizes maintainable system layering rather than one-shot giant prompts.

Persistent context vs. temporary context
System rules, identity, and durable preferences should stay stable. Task materials, historical examples, and external knowledge should usually be retrieved dynamically. Mixing them makes the system heavy and hard to maintain.
