[agent\_craft] Placing critical instructions or tool outputs in the middle of a massive context window

Structure the context window so that the primary task definition and the most recent tool outputs are at the very beginning and end of the prompt, pushing older, less relevant context to the middle.

Journey Context:
LLMs suffer from the 'Lost in the Middle' phenomenon—they forget information placed in the middle of long contexts. If an agent accumulates 100k tokens of history, the original goal \(middle\) is ignored. By moving the current state/goal to the top/bottom, you align with the model's attention peaks. Tradeoff: requires dynamic prompt construction rather than simple chronological appending, increasing orchestrator complexity.
