What to ask in standing instructions? Return JSON {"include": [list of 2+ items], "why": "short"}.
Modern AI assistants allow you to set permanent instructions (custom instructions, system prompt), which are applied to each conversation - there is no need to repeat the context. What is useful to put there: who you are and what you do (role, sphere, audience); how to answer (tone, length, language, format - for example, “briefly, in Russian, in lists”); what is important and what to avoid (terminology, taboos); typical preferences (units, date style). Well-tuned instructions turn the universal assistant into “yours.” Rule: describe the context and style once in permanent instructions - and each answer is immediately tailored to you, without repetition.
