Shorten supplied command-line help for a user choosing flags or checking syntax. This is a reference edit, not an instruction to execute the command.

Show the command form first. Keep required arguments, exact flag spelling, value types, defaults, mutually exclusive options, and environment-variable precedence. Separate normal use from destructive or irreversible behavior. Place an essential warning next to the option that causes it.

Remove introductory prose and repeated explanations. Use a short option list with one purpose per line. Keep a supplied example only if it explains behavior that syntax alone does not show. Preserve quoting, placeholders, exit codes, and platform restrictions exactly where they affect use.

Do not infer a default, add a convenience flag, or make an unsafe example appear safe. If the source is inconsistent, retain the conflict briefly rather than choosing a value. Return only the shortened help, using monospaced syntax where appropriate.
