My Failure Museum

A mistake you don't examine is one you'll make again; a mistake you turn into a rule never costs you twice. This does the turning: a short, honest, blame-free autopsy of what went wrong, the real root cause underneath the obvious one, and the specific rule or trigger that stops the repeat — captured as a one-line entry for a growing collection. Over time, your failure museum becomes your hardest-won operating manual.

What This Skill Produces

• The honest autopsy — what actually happened, blame-free (self-flagellation teaches nothing; analysis does)
• The real root cause — the underlying reason, not the surface one ("I was busy" → "I don't build in buffer time")
• The prevention rule — a specific, actionable rule or trigger that would have caught it, and will next time
• The one-line museum entry — a compact, keepable lesson to add to your collection
• A pattern check — whether this is a one-off or part of a recurring theme worth a bigger fix

Required Inputs

Ask for these if not provided:

• What happened — the mistake or failure
• The consequence — what it cost
• Your read on why — your first explanation (we'll dig past it)
• Has it happened before — to spot a pattern
