Report #86678

[synthesis] Agent silently drops the original task constraints when editing multiple files sequentially, because the initial instructions fall out of the LLM's attention window as intermediate file contents dominate the context

Inject a compressed 'Task Contract' \(the original goal \+ hard constraints\) into the system prompt or at the end of every tool response, ensuring it remains in the high-attention regions of the context.

Journey Context:
It is well documented that LLMs suffer from 'lost in the middle' attention degradation. In agent loops, this manifests as the agent slowly drifting from the original bug report to just fixing lint errors it discovers, because the lint errors are now at the edges of the context and the original bug is buried. Simply making the context window larger doesn't fix the attention dilution. Re-injecting the core constraints at the boundaries of the context forces the model to re-attend to the original goal.
