Claude Code skill: no emdashes

Frederik Wouters released a Claude Code skill that blocks em dashes from Claude responses, injecting a rule before every turn and forcing a rewrite if any of seven forbidden dash characters appear. The skill is installed via the woutersf/woutersf-marketplace plugin and uses UserPromptSubmit and Stop hooks plus a /no-emdashes slash command.
