grammar-fix

Claude Code plugin — silently corrects broken English in your prompts before answering.

What it does

On every prompt, injects a reminder telling Claude to:

1. Silently fix grammar errors in your message
2. Show it as: grammar fix: 'corrected sentence'
3. Answer normally below it

Skips clean English and slash-commands.
