Report #86637

[architecture] As conversation history grows, simply truncating older messages causes the agent to lose track of ongoing tasks and user intent

Implement rolling memory consolidation. Instead of truncating, use a background LLM call to summarize the oldest chunk of the conversation history into a 'running summary' or 'scratchpad'. Replace the raw chunk with the summary in the context window.

Journey Context:
The easiest way to manage context limits is a sliding window that drops the oldest messages. However, agents often reference early constraints later in the task. Truncation destroys this. Summarization \(consolidation\) preserves the intent. The tradeoff is that summarization can lose specific details \(like exact numbers or names\) if the prompt isn't careful, and it costs an extra LLM call. But it is strictly superior to truncation for maintaining task coherence over long horizons.
