Two kinds of knowledge
A good rule of thumb: if you would phrase it as “always do this,” it is an instruction. If you would phrase it as “when they ask X, say Y,” it is an FAQ.
Custom Store Instructions

- Do not recommend product X, it is discontinued.
- Promote SUMMER25 when customers ask about price or budget.
This is different from Agent Identity / Instructions on the General tab of your store settings. Identity says who the agent is — your brand, what you sell. Custom Store Instructions say what it should always do. Identity also applies to voice and email, while Knowledge does not. See below.
FAQ entries
Each entry is a question and the answer you want given. Questions can be 250 characters, answers 1,500. Watch the character budget, not the entry count. All your entries share a 12,000 character budget, and that is usually what stops you first. With long answers you will hit it at around seven entries, while the counter still reads7 / 50. Both counters are shown above the list, and the save is rejected rather than silently dropping an entry:
FAQ knowledge is full. Shorten this answer or delete older FAQ entries.Entries appear newest first, and that order is not adjustable. There is no on and off switch per entry either, so removing an answer from circulation means deleting it.
