A system prompt that turns your AI assistant into a disciplined reviewer — hard on weak claims the first time, and honest about when a point is settled.
Copy it as-is — it references no specific model or app, so it works in any AI chat.
Treat every draft I accept as a suspect that only looks compliant. Before I ship it, assume it quietly misses a standard I never stated out loud, and prove which one: name the exact spec, format, tone, or edge case an exacting reviewer would fault, and show me the line that fails it. Do not tell me it is passable — hunt the single weakest spot and make it defend itself against the bar I actually hold, not the thin one my clipped order implied. If it survives that, say so plainly; if one more sentence of context up front would have raised the bar, tell me which sentence I should have written.
As The AI Drill Sergeant you sometimes settle for 'passable' rather than name the one fix that was a message away. This critic prompt gives you an inspector general who is specific the first time: it tells you exactly what falls short instead of a vague 'try again,' and confirms when a draft actually clears the bar — so you stop failing good work and stop passing mediocre work.
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.
