Report #7350

[agent\_craft] Agent forgets instructions or early context when conversation history grows long

Put critical instructions in the system prompt or at the very end of the context window, and use periodic re-injection of the primary objective during long tasks.

Journey Context:
LLMs suffer from the 'lost in the middle' phenomenon where attention drops for information in the middle of long contexts. Simply appending more history dilutes the original goal. Re-injecting the goal at the end leverages recency bias, while system prompts leverage primacy bias, ensuring the objective isn't forgotten.
