# iolaus

Personal agents for Daedalus — powered by [Pallas](https://git.helu.ca/r/pallas).

Iolaus is a pure agent project: Python agent definitions + YAML configuration.
The runtime (serving, registry, health checks, multimodal support) lives in Pallas.

## Architecture

## Configuration

### `agents.yaml` — Deployment Topology

Single source of truth for agent names, ports, dependencies, host, and namespace.
Read by Pallas at startup.

```yaml
name: iolaus
version: "1.0.0"
host: puck.incus
namespace: ca.helu.iolaus
registry_port: 24000

agents:
  shawn:
    module: agents.shawn
    port: 24001
    title: Shawn
    description: "Personal general assistant — calendar, contacts, email, and daily life management"
    depends_on: [research]
  # ...
```

To deploy a different agent group, swap `agents.yaml` — no code changes needed.
Override the config path with `PALLAS_AGENTS_CONFIG` env var.

### `fastagent.config.yaml` — LLM + Model Capabilities

Committed to the repo. Contains LLM provider settings and explicit model capability
declarations.

```yaml
default_model: openai.Qwen3.5-35B-A3B-UD-Q4_K_XL.gguf

model_capabilities:
  vision: false
  context_window: 40960
  max_output_tokens: 8192
```

The `model_capabilities` section declares capabilities explicitly rather than
inferring from the model name. Exposed in the registry for Daedalus to use when
routing requests.

### `news:` — Mikael News Agent Configuration

Top-level block in `fastagent.config.yaml`, consumed by `agents/mikael.py` at
startup. Edits take effect on restart — no code changes needed to tweak
topics or sources.

```yaml
news:
  topics:
    - Canadian federal politics
    - Generative AI and LLM research
    # ... add/remove freely
  preferred_sources:          # seeded into queries, not exclusive
    - reuters.com
    - apnews.com
    - cbc.ca
  avoided_sources:            # excluded via -site: AND post-filtered by host
    - foxnews.com
    - breitbart.com
    - dailymail.co.uk
  default_lookback_hours: 24
  max_items_per_topic: 5
```

Mikael excludes `avoided_sources` from search results with `-site:` operators
*and* post-filters by hostname as a second line of defence. It will never
summarize or cite content from an avoided source, even if another outlet
syndicates the claim.

### `fastagent.secrets.yaml` — API Keys and Tokens

Gitignored — never commit. Place in the repo root alongside `fastagent.config.yaml`.

```yaml
openai:
  api_key: "your-key-here"

mcp:
  servers:
    angelia:
      headers:
        Authorization: "Bearer your-token"
    kairos:
      headers:
        Authorization: "Bearer your-token"
    periplus:
      headers:
        Authorization: "Bearer your-token"
    nike:
      headers:
        Authorization: "Bearer your-token"
    # ...
```

## Quickstart

```bash
# 1. Install dependencies (Python 3.13 required)
source ~/env/iolaus/bin/activate
pip install -e .

# 2. Configure secrets
cp fastagent.secrets.yaml.example fastagent.secrets.yaml
# Edit: set api_key and service tokens

# 3. Start all agents
iolaus

# 4. Verify
curl http://localhost:24001/mcp

# 5. Start a single agent
iolaus --agent shawn
```

## Daedalus Integration

Daedalus connects to agents via the MCP Python SDK's `streamable_http_client`.

Registry endpoint: `http://puck.incus:24000/.well-known/mcp/server.json`

The registry includes model capabilities on each agent entry:

```json
{
  "capabilities": {
    "model": "Qwen3.5-35B-A3B-UD-Q4_K_XL.gguf",
    "vision": false,
    "context_window": 40960,
    "max_output_tokens": 8192
  }
}
```

## Deployment (systemd)

```bash
# 1. Copy project to /srv/iolaus
sudo cp -r . /srv/iolaus
sudo chown -R iolaus:iolaus /srv/iolaus

# 2. Install into venv
cd /srv/iolaus
source ~/env/iolaus/bin/activate
pip install -e .

# 3. Configure secrets
cp fastagent.secrets.yaml.example fastagent.secrets.yaml
# Fill in API keys and tokens

# 4. Install and start systemd service
sudo cp systemd/iolaus.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now iolaus
sudo systemctl status iolaus
```

## Notes

- **Python 3.13** required (`fast-agent-mcp` pins `>=3.13`)
- **Runtime:** [Pallas](https://git.helu.ca/r/pallas) — `pallas-mcp @ git+ssh://git@git.helu.ca:22022/r/pallas.git`
- **Transport:** StreamableHTTP (`/mcp`) throughout — not SSE
- **LLM:** OpenAI-compatible API at `http://nyx.helu.ca:22079/v1` (personal Qwen model)
- **Logging:** Console output — stdout → syslog → Alloy → Loki in production
- **Port scheme:** registry at 24000, personal agents 24001–24049, sub-agents 24050–24099
