Fine-tune a small calibrated encoder classifier on Modal and rate it with gonogo. Every GPU launch goes through the human approval gate with the exact config shown; data checks and evaluation run locally for free.

## Good to know before installing

Thomas_encoder_train spends the user's Modal GPU credits and uploads the chosen training JSONL rows to Modal after the human approval gate; the base model is downloaded from Hugging Face on the Modal side. Training and inference run in a separate Python interpreter the user configures via THOMAS_PYTHON (with the author's thomas package, torch and modal installed); the Hermes venv only gets gonogo-eval. Runs and artifacts are written under HERMES_HOME/thomas/runs; the eval tool writes report files to the path the model supplies.

## 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 thomas
```

2. Said no? Turn it on later:

```bash
hermes plugins enable thomas
```

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
