Report #11511

[agent\_craft] Agent ignores early system prompt or tool schemas when conversation history grows long

Put critical instructions and tool schemas at the beginning and end of the context window. Periodically re-inject the core objective at the end of the context before triggering the next LLM call.

Journey Context:
LLMs suffer from 'lost in the middle' degradation. As tool call results pile up, the original task gets buried in the center of the context window. Simply appending to history dilutes the system prompt. Re-injecting or moving the most important context to the edges of the window preserves attention weights where the model actually looks.
