Report #44938

[agent\_craft] Why is my agent ignoring system instructions in long coding sessions?

Put the most critical instructions \(tool formats, safety constraints\) at the very beginning and very end of the context window. Use structured delimiters \(e.g., XML tags\) for intermediate context like file contents.

Journey Context:
LLMs exhibit 'lost in the middle' degradation. In long agentic loops, intermediate state \(scratchpads, read files\) pushes the original system prompt away from the attention horizon. Putting critical rules at the start and end ensures they fall in the high-attention regions, while intermediate context is clearly bounded to prevent instruction leakage.
