-- Added `AdapterType.OPENAI` to `ToolsSchema`, enabling custom OpenAI-specific tools (e.g. `tool_search`) in Chat Completions,Responses, and Realtime adapters.
+- `ToolsSchema` now accepts `custom_tools` for OpenAI LLM services (`OpenAILLMService`, `OpenAIResponsesLLMService`, `OpenAIResponsesHttpLLMService`, and `OpenAIRealtimeLLMService`), letting you pass provider-specific tools like `tool_search` alongside standard function tools.
