Replace litellm with direct OpenAI and Anthropic SDKs - #11
Merged
Conversation
Remove litellm dependency due to security concerns and replace with direct openai and anthropic SDK integrations as optional extras. - Add OpenAITranslator for OpenAI, Ollama, and Gemini (via OpenAI-compatible APIs) - Add AnthropicTranslator with thinking config mapping for reasoning effort - Extract shared helpers (_shared.py): prompt builders, retry decorator, JSON parsing, model name extraction, content validation - Add calculate_usage_cost() to cost.py (replaces litellm's completion_cost) - Add SDK presence checks to doctor.py diagnostics - Make openai/anthropic installable as extras: tinbox[openai], tinbox[anthropic] - Update factory to lazy-import translators based on ModelType - All 284 tests pass at 84% coverage
- Convert all str+Enum classes to StrEnum (Python 3.12+) - Use astral-sh/setup-uv in CI for faster installs - All ruff checks now pass (UP042 resolved)
