MDS066: commands-show-output

A fenced code block whose every non-blank line begins with $ and shows no output must drop the prompt.

# Config

Enable (default):

rules:
  commands-show-output: true

Disable:

rules:
  commands-show-output: false

# Autofix

mdsmith fix strips the leading $ from every non-blank content line of the offending block. Blank lines pass through unchanged. Only fenced code blocks are inspected; indented blocks are out of scope.

# Examples

# Good — block shows output

# Title

A block that shows both commands and their output is fine:

```sh
$ ls
foo bar
$ pwd
/home/user
```

# Good — no $ prompts

# Title

A block that has no `$ ` prefixes is fine:

```sh
ls
pwd
```

# Bad — only commands, no output

# Title

Commands shown with `$` and no output:

```sh
$ ls
$ pwd
```
