Prompt Spellcheck

Not yet reviewed

A Claude Code plugin that fixes spelling mistakes and typos in your prompt before the model reads it.

How to install

This mod is not in the official Claude directory, so you load it straight from its source on GitHub. modsforClaude.com is an unofficial community site: we do not host, repackage or install anything. Read the source and the review on this page first.

In the terminal

Clone the repository and start Claude Code with the mod. It stays loaded for that session.

git clone https://github.com/ljmerza/prompt-spellcheck
claude --plugin-dir ./prompt-spellcheck

In the desktop app

Clone the repository into a folder you keep:

git clone https://github.com/ljmerza/prompt-spellcheck ~/claude-mods/prompt-spellcheck

Add that folder to CLAUDE_CODE_PLUGIN_DIRS in the env block of ~/.claude/settings.json, then start a new session in the Code tab. On Windows, with your own user name:

"env": {
  "CLAUDE_CODE_PLUGIN_DIRS": "C:\\Users\\you\\claude-mods\\prompt-spellcheck"
}

On macOS and Linux:

"env": {
  "CLAUDE_CODE_PLUGIN_DIRS": "~/claude-mods/prompt-spellcheck"
}

Already loading other mods this way? Add the folder to the same value, separated by ; on Windows or : on macOS and Linux.

Claude Code plugin that fixes spelling mistakes and typos in your prompt before the model reads it.

you type: look uo claude code mods woth tests
model reads: look up claude code mods with tests
toast: ✎ spellcheck: uo→up, woth→with

When you press Enter, the plugin sends the prompt to a small, fast model (Haiku) with instructions to fix spelling only. Wording, punctuation, code, paths, URLs, flags and ticket keys stay as typed. The corrected text replaces the prompt, and a toast lists what changed.
