Vale Rule Generator

Generate a Vale YAML rule based on the following style requirement.

Output Format

Produce a single Vale YAML file with the following fields:

• extends — the Vale extension point (existence, substitution, occurrence, repetition, consistency, conditional, capitalization)
• message — an actionable message shown when the rule triggers; use %s where the matched text should appear
• level — suggestion, warning, or error
• tokens (for existence) or swap (for substitution) — the list of patterns or preferred replacements

Guidelines

• Use existence for terms to avoid outright
• Use substitution for preferred alternatives
• Prefer plain token lists over regular expressions unless the rule requires pattern matching
• Write message in the imperative: “Avoid ‘%s’.” or “Use ‘%s’ instead of ‘%s’.”
• Use level: suggestion for style preferences, level: warning for consistency requirements, level: error for hard violations
• Name the file in PascalCase matching the rule intent — for example, NoEmDash.yml or PreferSelect.yml
