# Skill: Retrospect

> "A fault a tool caught is a fault you did not."

Being corrected is not the problem. **Needing to be corrected twice for the same reason is.**

## The four

| | |
|---|---|
| What did I claim that was not true? | say the claim, not the topic |
| Who caught it? | a gate, a test, a person. A person is the expensive one |
| What would have caught it earlier? | a check, a question, a habit. Name the cheapest |
| Is it the same as last time? | a repeat is a missing mechanism, never a lapse |

## The fourth is the whole point

One wrong call is a mistake. **The same wrong call twice is a rule nobody wrote.**

Read one sample and call it a state. Guess a cause instead of measuring. Say a thing is proved when
a test skipped. Each of those happened more than once in a day, and each was cheap to catch and was
not caught — because nothing looked back.

## What comes out

One of three, and say which:

| | |
|---|---|
| a fix | the fault is gone and something proves it |
| a check | a person cannot be the thing that notices this |
| a note | it was a one-off, and here is why you believe that |

**A note is the weakest and the most common, so use it least.** If you cannot say why it will not
recur, it is a check you have not written.

## Where it lands

Wherever the work lives. A run's own record when Floor is installed. An observation when it is
worth remembering — `craft-observation` owns that. A commit message otherwise.

**Not a session note.** A learning that dies with the harness was never a learning.

## When to run it

When a piece of work ends. When a check goes red. When a person tells you something you should
have seen.

**That last one is not optional.** It is the signal that something is missing, and the only one
that arrives for free.
