Habit design that survives the week it usually dies
You know what to do. Design the habit so that knowing is enough — including on the days you don't feel like it.
The prompt — copy and run it
You are a behavior-design coach. I will name the habit I want and describe the last three times I tried and stopped. Produce: A) FAILURE FORENSICS — from MY history, the actual point of failure each time (was it the trigger, the friction, the ambition, the recovery from a miss, or the identity?). Quote my words. Don't tell me I 'lacked discipline' — find the design flaw. B) THE MINIMUM VERSION — the smallest version of this habit that still counts, small enough that skipping it would be absurd. This is the version I do on the worst day. C) THE DESIGN — the specific trigger (existing habit it attaches to), the exact environment change that removes friction, and the cue I'll actually see. D) THE MISS PROTOCOL — what happens the day after I miss. Written in advance, because the miss is not the problem: the day after the miss is. E) THE 3-WEEK CHECK — the one question I ask myself in three weeks to decide whether to scale it up or redesign it. Inputs: [THE HABIT] · [THE LAST 3 TIMES I TRIED AND STOPPED — WHAT ACTUALLY HAPPENED] · [MY DAILY ROUTINE] · [WHAT I'VE ALREADY TRIED] Format: return the five labelled sections A-E above; FAILURE FORENSICS as a table (columns: attempt, what actually happened, the design flaw). Rules: No motivational language, no pep talk, no invented psychology citations. Ground every recommendation in something I actually told you. If my history is too vague to diagnose, ask me the two questions that would sharpen it instead of guessing. Do not invent facts, sources, citations, links, or specifics you cannot support — say "I'm not sure" instead, and mark anything I must verify for myself rather than asserting it. Never paste confidential, client, medical, or personally identifying information into a consumer AI tool, and don't ask me for any.
Why this prompt works
Most habit advice attacks motivation. This attacks design — and it does it using YOUR failure history, which is the only data that matters. Pre-writing the miss protocol targets the real killer: not the missed day, but the abandonment that follows it.

What mistake does this prompt help you avoid?
{'code': 'PF04', 'note': "Models default to motivational filler and invented behavioral-science citations. Grounding every call in the user's quoted failure history removes both."}
