# Gerhard Hermes architecture

## Identity

Gerhard Rug is the first priority Hermes agent in Agent0.

Gerhard's identity file is:

```text
agents/gerhard-hermes/SOUL.md
```

Inside the container, Hermes home is:

```text
/opt/data
```

So Gerhard reads his soul at:

```text
/opt/data/SOUL.md
```

## Container mounts

Gerhard is expected to mount:

```text
./agents/gerhard-hermes   -> /opt/data
./agents/gerhard-workspace -> /workspace
../gutasktool             -> /opt/gutasktool
./shared/knowledge        -> /knowledge
${HOME}/.ssh              -> /root/.ssh
```

`/opt/gutasktool` is read-write so Gerhard can improve gutasktool, commit, and push to Gitea when instructed or when a task requires it.

`/knowledge` is the shared library. It is not Hermes memory. It is version-controlled institutional knowledge.

## Environment

Gerhard receives local credentials from Agent0's host-local `.env` via Docker Compose.

Expected variables include:

- `API_URL`
- `CONTENT_API_KEY`
- `AGENT_ID`
- `AGENT_NAME`
- `AGENT_PASSWORD`
- provider keys such as `ANTHROPIC_TOKEN` when needed

Do not commit these values.

## gutask access

Gerhard has a wrapper at:

```text
/opt/data/bin/gutask
```

The wrapper runs:

```bash
python3 /opt/gutasktool/gutasktool/cli.py "$@"
```

Use the absolute path in cron prompts because container `PATH` may vary:

```bash
/opt/data/bin/gutask orient --agent "$AGENT_ID"
```

## Scheduled orientation

The desired source of truth for Gerhard scheduled jobs is:

```text
agents/gerhard-hermes/cron/desired-jobs.json
```

Hermes live cron runtime state is stored in `cron/jobs.json` and should remain ignored because it mutates as jobs run.

On wake, Gerhard should:

1. Read `/opt/data/SOUL.md`.
2. Read `/knowledge/README.md` and relevant shared knowledge files.
3. Run `/opt/data/bin/gutask orient --agent "$AGENT_ID"`.
4. Use the returned task orientation as current work context.
5. Keep final reports short, in Gerhard voice.

## Runtime state

Do not version Hermes runtime state unless explicitly reviewed.

Examples to keep ignored:

- `agents/gerhard-hermes/state.db*`
- `agents/gerhard-hermes/sessions/`
- `agents/gerhard-hermes/logs/`
- `agents/gerhard-hermes/gateway_state.json`
- `agents/gerhard-hermes/channel_directory.json`
- `agents/gerhard-hermes/cron/jobs.json`
- `agents/gerhard-hermes/cron/output/`
