Rule-based proofreading for Japanese business text: finds and fixes AI-style phrasing (stock phrases, monotonous sentence endings, overused symbols and Markdown, English-calque grammar) with line, column and a fix hint. It checks wording, not authorship, and rarely flags plain model output. A transform_llm_output hook checks every final Japanese answer and only reports by default; opt-in enforce mode rewrites flagged answers with the user's own model and delivers the rewrite only if numbers, names, URLs, code and negation survive and the score drops under the threshold.

## Good to know before installing

No network calls of its own; enforce mode sends each flagged answer to the user's configured model (one extra call, a second only when the first rewrite fails the checks or stays over the threshold; extra cost and up to 25 s delay); a read-only post_tool_call hook notes turns with MEDIA: lines so attachments from other plugins are kept; reports stay in process memory on local surfaces only. Disclosure — no network calls of its own; mode report (default) only logs scores; opt-in mode enforce sends each flagged final answer (with finding excerpts) to the user's configured model via ctx.llm (1–3 calls, up to 25 s delay) and replaces the delivered and stored answer when its preservation checks pass, which do not prove meaning is unchanged; reads plugins.hook_callback_timeout via a private read-only Hermes helper; eval/ dev scripts ship in the tree but are never loaded.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install ja-writing-guard
```

2. Said no? Turn it on later:

```bash
hermes plugins enable ja-writing-guard
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
