Report #6031

[agent\_craft] Dynamic context injected into the system prompt dilutes core instructions and degrades instruction following

Separate the static system prompt \(persona, core rules\) from dynamic context \(retrieved documents, current state\). Inject dynamic context as a user/assistant turn or in a dedicated block at the end of the prompt, not interspersed with the core rules.

Journey Context:
Developers often append retrieved documents or state updates directly to the system prompt. As the system prompt grows, the attention weight on the actual rules \('Never delete files without asking'\) decreases. The model treats the whole system prompt as equally important background noise. By keeping the system prompt lean and moving dynamic context to a distinct turn or block, the model clearly distinguishes between 'rules I must follow' and 'data I must process'.
