Section 1
The premise
AI can explain context-rot patterns and design mitigations, but production retrieval and prompting changes need engineering execution.
What AI does well here
- Generate needle-in-haystack test plans for your specific model.
- Draft prompt-restructuring patterns that mitigate middle-context loss.
What AI cannot do
- Predict context-rot behavior without measurement.
- Substitute for engineering work on retrieval pipelines.
