# Malformed YAML Probe
This skill's frontmatter description contains an unquoted colon, which is
technically invalid YAML ("mapping values are not allowed here" in strict
parsers) but is a common authoring mistake that some clients' parsers
tolerate or repair. The client implementation guide recommends a lenient
fallback; this skill tests whether the platform has one.
