# Screen a post before it goes up

Judge a post against each rule on its own. `decide` asks one narrow question per rule.

*The post calls the author an idiot. decide says true and exits 0.*

```
question="Does this post insult someone?"

cat <<'EOF' |
The author is an idiot and this take is lazy.
EOF
thinkthen decide "$question"
```

*Output*

```
true
```

*exit 0: yes*

*The post is not spam. decide says false and exits 1.*

```
question="Is this post spam?"

cat <<'EOF' |
The author is an idiot and this take is lazy.
EOF
thinkthen decide "$question"
```

*Output*

```
false
```

*exit 1: no*
