Community (non-official) plugin that rewrites Hermes terminal commands through RTK (rtk-ai/rtk, Apache-2.0) before execution, so the model sees compact output instead of raw command spam — cutting tokens on common dev commands. Adds a fail-open pre_tool_call hook (2s timeout, unexpected exits leave the command untouched), an optional desktop pane, and update scripts.

## Good to know before installing

Every terminal tool command is passed to the rtk binary found on PATH (rtk-ai/rtk, installed separately) and replaced with rtk's rewrite before approval and execution; fail-open when rtk is missing or errors. Community mirror of upstream's hooks/hermes/rtk-rewrite, not affiliated with rtk-ai. scripts/update.sh downloads the pinned RTK release binary (v0.49.0, checksum-verified).

From the plugin's catalog listing.

## 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 rtk-rewrite
```

2. Said no? Turn it on later:

```bash
hermes plugins enable rtk-rewrite
```

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
