+# Tech Stack & Build
+
+## Language & Runtime
+
+- Python 3.11+
+
+## Core Frameworks & Libraries
+
+| Layer | Technology |
+|---|---|
+| Web framework | Flask 3.x + Flask-CORS |
+| ORM / Database | SQLAlchemy 2.x (MySQL via PyMySQL, SQLite for dev) |
+| Real-time comms | `websockets` library (standalone server on port 8765) |
+| Caching | Redis 5.x client + hiredis |
+| LLM integration | OpenAI-compatible API (default provider: Qwen/通义千问 via DashScope) |
+| Embedding | `sentence-transformers` with `BAAI/bge-small-zh-v1.5` (local, optional) |
+| NLP | jieba (Chinese word segmentation), scikit-learn (TF-IDF) |
+| Feishu SDK | `lark-oapi` 1.3.x (event subscription 2.0, long-connection mode) |
+| Data validation | pydantic 2.x, marshmallow |
+| Auth | JWT (`pyjwt`), SHA-256 password hashing |
+| Monitoring | psutil (in-process), Prometheus + Grafana (Docker) |
+
+## Configuration
+
+- All config loaded from environment variables via `python-dotenv` → `src/config/unified_config.py`
+- Singleton `UnifiedConfig` with typed dataclasses (`DatabaseConfig`, `LLMConfig`, `ServerConfig`, etc.)
+- `.env` file at project root (see `.env.example` for all keys)
+
+## Common Commands
+
+```bash
+# Install dependencies
+pip install -r requirements.txt
+
+# Initialize / migrate database
+python init_database.py
+
+# Start the full application (Flask + WebSocket + Feishu long-conn)
+python start_dashboard.py
+
+# Start only the Feishu bot long-connection client
+python start_feishu_bot.py
+
+# Run tests
+pytest
+
+# Code formatting
+black .
+isort .
+
+# Linting
+flake8
+mypy .
+```
+
+## Deployment
+
+- Docker + docker-compose (MySQL 8, Redis 7, Nginx, Prometheus, Grafana)
+- Nginx reverse proxy in front of Flask (port 80/443 → 5000)
+- Default ports: Flask 5000, WebSocket 8765, Redis 6379, MySQL 3306
+
+## Code Quality Tools
+
+- `black` for formatting (PEP 8)
+- `isort` for import sorting
+- `flake8` for linting
+- `mypy` for type checking
