kind field inside the brain_provider object in your config.json. Three providers are available out of the box, covering everything from fully deterministic operation to cloud-scale LLM inference.
Provider Overview
- rules
- ollama
- openai-compatible
The
rules provider uses a built-in, deterministic decision engine — no LLM is required. It is the fastest way to get the runtime running and is well-suited for environments where you want predictable, auditable behaviour without any external model dependency.Because
rules makes no network calls, it works fully offline and requires no additional credentials or services.Configuration Schema
All brain provider configurations share a common shape. The table below lists every supported field.| Field | Required for | Type | Description |
|---|---|---|---|
kind | all | string | Provider type: rules, ollama, or openai-compatible |
base_url | ollama, openai-compatible | string | Base URL of the inference API |
model | ollama, openai-compatible | string | Model identifier to request |
api_key_env | openai-compatible | string | Name of the env var that holds the API key |
Using a Docker-Hosted Brain Provider
When the Wattetheria stack runs inside Docker and your AI gateway or Ollama instance is a process on the host machine, you must use Docker’s special hostname in place oflocalhost or 127.0.0.1:
host.docker.internal resolves automatically on Docker Desktop (macOS and Windows). On Linux, add extra_hosts: ["host.docker.internal:host-gateway"] to the relevant service in your Compose file.Using the Supervision Console
You do not have to editconfig.json by hand to change the brain provider. The supervision console at http://127.0.0.1:7777/supervision includes a dedicated UI card for this purpose. Changes made through the console are written directly to the deploy .env file and take effect on the next restart — no file editing required.
Validating the Brain Provider
After any change to the brain provider — whether viaconfig.json, the .env, or the supervision console — run the diagnostics command to confirm that the runtime can reach the model and that agent attach status is current:
CLI Brain Commands
Thewattetheria brain sub-command lets you invoke the brain provider directly from the command line for testing and introspection. Both commands operate against the runtime state directory.
Use propose-actions to ask the brain to generate a set of candidate agent actions based on current runtime state:
humanize-night-shift to produce a human-readable summary of agent activity over a given time window (in hours):
