goat

A personal assistant backend. It stores facts in Postgres or SQLite, fills them from importers on a schedule, and answers questions about them over Slack, MCP, SMS, or a terminal REPL.

Facts carry two timestamps: when the fact is about, and when goat learned it. Re-running an importer with unchanged data writes nothing.

Install

uv add "goat-butler @ git+https://github.com/phin-tech/goat"

Extras: postgres, agent (pydantic-ai), cli, mcp, slack, sms, weather, migrations, and all for every one of them. SQLite needs none.

uv add "goat-butler[all] @ git+https://github.com/phin-tech/goat"

To work on goat itself:

git clone https://github.com/phin-tech/goat
cd goat
uv sync
uv run pytest

The suite runs against both SQLite and Postgres. Postgres comes from docker compose up -d.

Start a shed

A shed is one deployment: a directory with a shed.py that builds a Shed, and a .env holding the credentials. goat init writes both.

uv run goat init ~/my-shed
cd ~/my-shed
uv sync
goat migrate
goat ingest
goat repl

Defaults to SQLite, so this runs with no database server and no API key. Set a model provider key in .env for goat brief and the REPL's ask.

.env can hold 1Password references instead of secrets. goat resolves them at startup via the op CLI, so the file is safe to read aloud or paste:

OPENROUTER_API_KEY=op://Private/OpenRouter/credential

Commands

What goes where

goat holds the mechanism: the store, importers, delivery, tools, the CLI. A shed holds the values: coordinates, model, credentials, prompt, schedule. OpenMeteoImporter lives in goat because a latitude is a constructor argument. The latitude lives in your shed.
