Report #24392

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

Re-inject the primary objective and critical constraints at the very end of the context window \(right before the generation prompt\) rather than relying solely on the system prompt at the beginning.

Journey Context:
LLMs suffer from 'lost in the middle' degradation; attention scores dip for tokens in the middle of long contexts. While the system prompt is safe at the top, dynamic history pushes it out of the recency bias zone. Re-stating the goal at the end ensures it sits in the highest-attention real estate, anchoring the agent's next action to the original goal rather than the most recent tool output.
