Report #83583

[synthesis] Agent loses track of the original goal or current file state after many sub-task iterations

Periodically inject a state summary prompt \(current goal, current file, last action result\) into the context, and use a sliding window or RAG for historical steps rather than keeping all raw steps in context.

Journey Context:
As agents perform long tasks \(e.g., migrating 20 files\), the context window fills with the history of previous files. The LLM's attention mechanism naturally focuses on the most recent tokens. The agent slowly forgets the original architectural constraints or the state of files modified early in the process, leading to inconsistencies. Simply increasing the context window doesn't help; it actually increases the noise. Actively managing the context to maintain a crisp, updated state summary is required.
