An enterprise assistant's system prompt carries 25 departmental procedures (expense filing, visa letters, data-access requests and so on). Most requests use one procedure or none. Costs are high, and answers sometimes apply the wrong department's procedure. What is the most appropriate change?

Answer: B — Package the procedures as Skills, so only short descriptions are always present and full text loads when relevant

(b) is right: progressive disclosure keeps every procedure available while loading only the relevant one, cutting tokens and removing the distraction that causes wrong-procedure answers. (a) reduces the cost of the repeated prefix but not the confusion from irrelevant procedures. (c) forces users to pick the right assistant and multiplies maintenance. (d) trims tokens but keeps all 25 procedures competing for attention and may lose needed detail.
