 """
 Constants and configuration for Claude Code OpenAI Wrapper.
-
-Single source of truth for tool names, models, and other configuration values.
-
-Usage Examples:
-    # Check if a model is supported
-    from src.constants import CLAUDE_MODELS
-    if model_name in CLAUDE_MODELS:
-        # proceed with request
-
-    # Get default allowed tools
-    from src.constants import DEFAULT_ALLOWED_TOOLS
-    options = {"allowed_tools": DEFAULT_ALLOWED_TOOLS}
-
-    # Use rate limits in FastAPI
-    from src.constants import RATE_LIMIT_CHAT
-    @limiter.limit(f"{RATE_LIMIT_CHAT}/minute")
-    async def chat_endpoint(): ...
-
-Note:
-    - Tool configurations are managed by ToolManager (see tool_manager.py)
-    - Model validation uses graceful degradation (warns but allows unknown models)
-    - Rate limits can be overridden via environment variables
