This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Build & Run Commands

# Install dependencies
pip install -r requirements.txt

# Run the bot (requires .env with DISCORD_TOKEN and AI provider key)
python -m daemon_boyfriend

# Run with Docker
docker-compose up -d

# Syntax check all Python files
python -m py_compile src/daemon_boyfriend/**/*.py

Architecture

This is a Discord bot that responds to @mentions with AI-generated responses (multi-provider support).

Provider Pattern

The AI system uses a provider abstraction pattern:

• services/providers/base.py defines AIProvider abstract class with generate() method
• services/providers/openai.py, openrouter.py, anthropic.py, gemini.py implement the interface
• services/ai_service.py is the factory that creates the correct provider based on AI_PROVIDER env var
• OpenRouter uses OpenAI's client with a different base URL
• Gemini uses the google-genai SDK

Cog System

Discord functionality is in cogs/:

• ai_chat.py - @mention handler (responds when bot is mentioned)

Cogs are auto-loaded by bot.py from the cogs/ directory.

Configuration

All config flows through config.py using pydantic-settings. The settings singleton is created at module load, so env vars must be set before importing.

Web Search

The bot can search the web for current information via SearXNG:

• services/searxng.py provides SearXNGService for web queries
• ai_chat.py uses a two-step approach: first asks AI if search is needed, then provides results as context
• Search is triggered automatically when the AI determines the query needs current information
• Configured via SEARXNG_URL, SEARXNG_ENABLED, and SEARXNG_MAX_RESULTS env vars

Key Design Decisions

• ConversationManager stores per-user chat history in memory with configurable max length
• Long AI responses are split via split_message() in ai_chat.py to respect Discord's 2000 char limit
• The bot responds only to @mentions via on_message listener
• Web search uses AI to decide when to search, avoiding unnecessary API calls for general knowledge questions

Environment Variables

Required: DISCORD_TOKEN, plus one of OPENAI_API_KEY, OPENROUTER_API_KEY, ANTHROPIC_API_KEY, or GEMINI_API_KEY depending on AI_PROVIDER setting.

Optional: SEARXNG_URL for web search capability.
