Skill name
One or two lines on what this is for, and what goes wrong without it.
1. The first rule
State the rule, then why it exists. If it has never gone wrong in practice, it is advice rather than a skill — cut it.
Show the wrong thing next to the right thing:
bad() <- what this breaks
good() <- why this is safe
2. The next rule
Use a table when there are cases to enumerate:
| Case | What to do |
|---|---|
| ... | ... |
Checklist
- The thing to verify, phrased so it can be answered yes or no
- One per rule above
