FAQ
Questions Context Window Optimizer owners ask.
- 01
How does the selection process work?
The engine uses a deterministic greedy approach. It sorts all candidate items by relevance score (descending) and then by recency (descending), adding them to the selection until the token limit is reached.
- 02
Can I reserve specific messages?
Yes, you can use select_optimal_context with the reserve_system_prompt or reserve_last_user_message flags to ensure critical information is always included.
- 03
What is the optimization score?
The optimization score is a metric returned by the selection capability that represents the aggregate relevance of the items successfully selected within your budget.
