No-em-dash hook
A PostToolUse hook that blocks em dashes from being written to files.
A deterministic gate. The model cannot talk its way past it. Register in settings.json:
{
"hooks": {
"PostToolUse": [
{
"matcher": "Edit|Write|MultiEdit",
"hooks": [
{
"type": "command",
"command": "node .claude/hooks/no-emdash.mjs"
}
]
}
]
}
}The script greps the edited file for em and en dashes and exits non-zero with a message if it finds any, which feeds the failure back to the model as a correction.
