My Failure Museum

Q: How do I know the My Failure Museum output is good?

The skill verifies itself against its own 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.

Turn a mistake into a reusable lesson — a short, unsentimental 'here's what happened and the rule so it doesn't happen again' entry you can actually keep. Use when asked help me learn from this mistake, I keep making the same error, capture this lesson, or turn this failure into something useful. Produces an honest, blame-free autopsy of what happened, the real root cause (not the surface one), the specific rule or trigger that prevents a repeat, and a one-line entry for your growing 'failure museum' — because unexamined mistakes repeat and examined ones compound into wisdom.

🗣 Say this to your agent

“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?”

What to give it

▸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

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓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

⚠️ What it refuses to do

**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.**
