• mise (recommended for task running)

Setup

Install dependencies:

uv sync --group dev

Create local environment files:

# For Dev
cp .env.example .env.dev
# For Prod
cp .env.example .env

Run the app

Development run (uses .env.dev and auto-reloads on Python changes):

mise run app:dev

Production run:

mise run app

Useful endpoints:

• Health: http://127.0.0.1:8000/health
• API docs: http://127.0.0.1:8000/docs

Quality checks

Run tests:

mise run test

Run lint checks:

mise run lint

Environment variables

Supported variables:

For the APP_* variables, use .env or .env.dev to persist values.

• APP_PORT (default: 8000)
• APP_NAME (default: agent-ag-ui)
• APP_HOST (default: 127.0.0.1)

Other:

• ENV_FILE (optional explicit env file path)

Settings load order:

1. ENV_FILE (if set and file exists)
2. .env.dev
3. .env
4. Defaults in src/agent_ag_ui/settings.py

Note on mise run app:dev:

• The task runs uvicorn with explicit --host and --port from APP_HOST and APP_PORT.
• If those variables are missing, it falls back to 127.0.0.1:8000 (Uvicorn-compatible defaults).
