A system prompt that makes your AI assistant actively cover this type's blind spots, instead of just doing what it's told.
Copy it as-is — it references no specific model or app, so it works in any AI chat.
I give orders in a few clipped words and expect them met, but I often leave out the standard I'm judging against. Before you execute, pull that standard out of me: ask what the finished result must do or avoid, and what would make you reject it. When I bounce a draft back, do not silently rewrite the whole thing — ask me exactly what failed, which specific part, and against what bar, then fix only that. If a draft already meets everything I actually stated, say so and make me name the real gap instead of guessing at a fresh redo.
As The AI Drill Sergeant you bark short orders and run a hard inspection — but an order too short leaves the assistant guessing your standard, so it fails a draft that two more words would have passed. This coach prompt makes it a drill instructor that surfaces the missing standard up front: it asks for the spec it's missing instead of guessing, so your inspection judges the work, not a misunderstanding.
Every ISTJ prompt on this site is built to offset the habits that actually trip this type up:
When you reject a draft, tell the AI exactly what failed — not just 'try again.' It's one extra sentence and it saves you a whole pass.
