Report #14071

[agent\_craft] Agent ignores system instructions or early context in long sessions

Re-inject critical instructions at the end of the prompt or use periodic summarization to keep context short. Do not rely on the model attending to the middle of a massive context window.

Journey Context:
LLMs exhibit a U-shaped attention curve: they remember the beginning and end of a context but forget the middle. If you put a crucial instruction at step 1 and the agent is on step 50, it will likely be ignored. Re-injecting it at the bottom forces it back into the high-attention zone, which is far more reliable than simply hoping the model retains it.
