no emdashes - ever!!

Blocks em dashes from Claude responses. Injects the rule before every turn and forces a rewrite if one slips through.

Background and the why behind it: Claude skill: no emdashes.

Install

install from woutersf-marketplace

/plugin marketplace add woutersf/woutersf-marketplace

/plugin install no-emdashes@woutersf-marketplace

How it works

• Stop hook: scans the response; if a forbidden character is found, blocks Claude and forces a rewrite
• /no-emdashes: slash command for an on-demand check
