Optimize context windows and manage token usage
Context-window management: what to put in, what to leave out, and what to do when the material exceeds the budget. Summarisation, truncation strategy and ordering effects all appear here, as does the fact that a full context window is not a free one. Cost and latency both scale with it, and recall over very long contexts is not uniform. A stem that says "we are passing the entire document set" is usually pointing at retrieval instead.
