7. Opt-Out Feature

Users can control whether they are tagged in bot-generated messages (summaries, answers) by sending Direct Messages (DMs) to the bot:

| Command | Description | | :-------- | :--------------------------------------------------------------------------------- | | opt-out | Opt-out of being tagged. Your name will be displayed as text instead of a mention. | | opt-in | Opt-in to being tagged (default). | | status | Check your current opt-out status. |

Note: This only affects messages generated by the bot. It does not prevent other users from tagging you manually.

🚀 Production Deployment

1. Create Production Environment File: Copy .env.example to .env.prod and configure your production secrets.

   cp .env.example .env.prod
   

2. Start Services:

   docker compose -f docker-compose.prod.yml up -d
   

This configuration includes:

• Automatic restart policies (restart: always)

Developing

Setup

Install dependencies using uv:

uv sync --all-extras --dev

Development Commands

The project uses Poe the Poet for task automation with parallel execution:

# Run all checks (format, then parallel lint/typecheck/test)
uv run poe check

# Individual tasks
uv run poe format     # Format code with ruff
uv run poe lint       # Lint code with ruff
uv run poe typecheck  # Type check with pyright
uv run poe test       # Run tests with pytest

# List all available tasks
uv run poe

The check command runs formatting first, then executes linting, type checking, and testing in parallel for faster execution.
