[agent\_craft] Model ignores the key requirement hidden in the middle of a long prompt

Place task-critical instructions and references at the very start or very end of the context; never bury them between large blocks of code or history.

Journey Context:
LLMs exhibit a U-shaped attention curve over long inputs: information at the beginning and end is recalled best, middle content degrades. 'Lost in the Middle' quantified this across models, so layout is a first-class context engineering decision.
