These should not successfully parse as a Caddyfile:

log_skip {
    path /api/* /socket/*
}

log_skip foo bar

👆 this is a config based on misunderstanding how matchers work, and should be rejected during unmarshal. If there's a block ({ }), or any arguments at all, then it should return an error immediately.

A correct config would look like this:

@skipped path /api/* /socket/*
log_skip @skipped
