I’m not a native English speaker, and I write a lot of prompts in English. Auto-correction is useful, but it doesn’t really teach you much because the mistake disappears for you. So I made Prompt English Coach plugin . It does not rewrite your prompt before Claude sees it. Claude still gets exactly what you typed. It also does not pollute the main Claude context in the non-blocking modes. The feedback is shown after Claude finishes answering, so you can safely use it without the coach note becoming part of the prompt Claude is responding to. Modes which can be used:
gentle : one short hint after Claude answers
coach : suggested version + a few quick explanations after Claude answers
gate : blocks the prompt only when there is a meaningful grammar or clarity issue, so you have to rewrite it yourself
strict : same blocking idea, but with fuller feedback Example: Your prompt: “I doesn’t need explanation.” Hint in the end:
- Suggested version: “I don’t need an explanation.”
- Focus: Use “don’t” with “I”, Add “an” before “explanation”. The main idea is deliberate practice, not invisible auto-correct. It’s open source / MIT: https://github.com/awkoy/prompt-english-coach How to install, run two commands into your session: /plugin marketplace add awkoy/prompt-english-coach /plugin install prompt-english-coach@prompt-english-coach Disclosure: I built this plugin. It is free and open source, with no paid plan or referral link. I’d be happy to hear feedback, ideas, or feature requests from people who use Claude Code daily, especially around the default mode and whether gate mode feels useful or annoying =) submitted by /u/Working-Forever-7106
