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
Framework: Autopsy Without Blame, Extract The Rule
- Examine, don't flagellate. Approach it like an investigator, not a judge — blame shuts down learning; curiosity opens it.
- Dig past the surface cause. "I forgot" or "I was busy" is rarely the real cause — find the system or habit underneath ("no reminder system," "I over-commit").
- Extract a specific rule. Convert the root cause into an actionable rule or trigger ("before saying yes, check the calendar"; "always CC myself"). Vague resolutions don't work; specific rules do.
- Write the one-liner. Compress it into a single memorable entry for the museum — short enough to actually reread.
- Check the pattern. If this echoes past failures, name the recurring theme — that's the higher-leverage fix.
Output Format
Failure: [what happened] · cost: [consequence]
Autopsy (blame-free): [what actually happened]. Real root cause: [the underlying system/habit, past the surface]. Prevention rule: [specific, actionable rule or trigger]. 📓 Museum entry (one line): "[compact lesson]." Pattern? [one-off / part of a recurring theme → the bigger fix].
Quality Checks
- The autopsy is honest but blame-free
- It digs past the surface cause to the real one
- The prevention is a specific rule/trigger, not a vague resolution
- It produces a compact, keepable one-line entry
- It checks whether this is part of a pattern
Anti-Patterns
- Self-flagellation dressed as reflection.
- Stopping at the surface cause ("I was careless").
- A vague resolution ("I'll be more careful") instead of a rule.
- Missing the recurring pattern.
Example Trigger Phrases
- "I messed up — help me actually learn from it."
- "I keep making the same mistake. Why, and how do I stop?"
- "Turn this failure into a lesson I'll remember."
- "Do a blame-free post-mortem on my screw-up."
- "Add this to my list of lessons — what's the rule?"
