D5 Context Management & Reliability · Paper 4

A customer support agent handles a multi-issue session. After several turns, the agent refers to 'your recent refund request' instead of the specific $247.83 refund for order #8891. The conversation history is being summarised between turns to manage context length. What is the most effective fix?

• A.Store the full conversation in an external database and retrieve only the relevant turns on demand.
• B.Extract transactional facts into a persistent case facts block outside the summarised history.
• C.Instruct the model to preserve every amount, date, and order number verbatim whenever it summarises earlier turns.
• D.Increase the context window size so that summarisation can be avoided entirely for the whole session.

Show answer & explanations

Correct answer: B

A: This adds infrastructure complexity without addressing the core issue of which facts must persist in every prompt.

B: This directly addresses the progressive summarisation trap by ensuring critical numerical and transactional data is never condensed.

C: Prompt-based instructions for summarisation are unreliable — the model will still compress details probabilistically.

D: This postpones the problem but does not solve it — eventually the context will fill, and summarisation will still destroy specifics.
