TLDR: We are introducing a new tool_calls attribute on AIMessage. tools I recently followed the community advice to resolve the conflict between args_schema and ToolRuntime by adding a runtime: ToolRuntime field to my Pydantic schema Hi all, While declaring a tool, I’m using the args_schema field to annotate each argument of the tool properly. """ user_id: str @tool def get_user_location(runtime: ToolRuntime[Context]) -> str: Agents go beyond simple model-only tool binding by facilitating: Multiple tool calls in sequence (triggered by a single prompt) Parallel tool calls when After create a graph, I can set context when use invoke(), but for function astream_events, there is not params for context, is there a workaround i can follow? I recently followed the community advice to resolve the conflict between args_schema and ToolRuntime by adding a runtime: ToolRuntime field to my Pydantic I’m trying to access my LangGraph state from inside a tool using ToolRuntime. You can find a list of all models that support tool calling. My state is defined as: class BasicChatState (TypedDict): user_query: Optional [str] Additionally, I rewrote the convert_mcp_tool_to_langchain_tool function to remove parameters from the inputSchema during the conversion process and re-inject those 詳細ã®è¡¨ç¤ºã‚’試ã¿ã¾ã—ãŸãŒã€ã‚µã‚¤ãƒˆã®ã‚ªãƒ¼ãƒŠãƒ¼ã«ã‚ˆã£ã¦åˆ¶é™ã•れã¦ã„ã‚‹ãŸã‚表示ã§ãã¾ã›ã‚“。 LangChain is an open source framework with pre-built agent architectures and standard integrations for any model or tool. ã¯ã˜ã‚ã« å‰å›žã¨å‰ã€…回ã§tool callingã¨toolã®å®Ÿè¡Œã‚’行ã„ã¾ã—ãŸã€‚ ãªã‚“ã‹ã€å«Œãªæ„Ÿã˜ã—ã¾ã›ã‚“ã§ã—ãŸï¼Ÿ ã“れã€äººãŒtool callingã—ãŸã‹ã©ã†ã‹ã‚’判別ã—ãªã„ã‹ã‚“ã‚„ã‚“ ã¨ã„ㆠTool Calling ã¨ã¯ãªã«ã‹ï¼Ÿ LangChainã§ã¯ã€LLMï¼ˆå¤§è¦æ¨¡è¨€èªžãƒ¢ãƒ‡ãƒ«ï¼‰ã‹ã‚‰å¤–部機能(関数ãªã©ï¼‰ã‚’呼ã³å‡ºã™æ©Ÿèƒ½ã‚’「Tool Callingã€ã¨å‘¼ã³ã¾ã™ã€‚ Tool Callingã¯ã€LLM㌠ãŸã¨ãˆã°ã€ã€ŒGitHub Toolkitsã€ã«ã¯ã€ã€ŒGitHub ã®å•題を検索ã™ã‚‹ãŸã‚ã®Toolã€ã€Œãƒ•ァイルをèªã¿å–ã‚‹ãŸã‚ã®Toolã€ã€Œã‚³ãƒ¡ãƒ³ãƒˆã™ã‚‹ãŸã‚ã®Toolã€ãªã©ãŒå«ã¾ã‚Œã¦ã„ã¾ã™ã€‚ ã“ã®ã‚¬ã‚¤ãƒ‰ã§ã¯ã€LangChainã§ãƒ©ãƒ³ã‚¿ã‚¤ãƒ 値をツールã«ãƒã‚¤ãƒ³ãƒ‰ã™ã‚‹æ–¹æ³•を説明ã—ã¾ã™ã€‚ ユーザーIDãªã©ã®ãƒ‘ãƒ©ãƒ¡ãƒ¼ã‚¿ã‚’å®‰å…¨ã«æ‰±ã†å¿…è¦æ€§ã‚„ã€LLMãŒç‰¹å®šã®ãƒ„ール引数を生æˆã—ãªã„よã†ã« LangChainã‚„AWS Bedrockãªã©ã®LLMフレームワークã¨é€£æºã—ã€Difyã‚„Langflowã®ã‚ˆã†ãªãƒŽãƒ¼ã‚³ãƒ¼ãƒ‰ãƒ„ールã¨ã‚‚çµ±åˆå¯èƒ½ã€‚ APIを利用ã—ã¦ã‚«ã‚¹ã‚¿ãƒ ワークフãƒãƒ¼ã‚’ LangChainã¯ã€ãƒ‰ã‚ュメント分æžã‚„è¦ç´„ã€ãƒãƒ£ãƒƒãƒˆãƒœãƒƒãƒˆã€ã‚³ãƒ¼ãƒ‰è§£æžãªã©ã€ã•ã¾ã–ã¾ãªãƒ¦ãƒ¼ã‚¹ã‚±ãƒ¼ã‚¹ã«å¯¾å¿œã™ã‚‹æ©Ÿèƒ½ã‚’æä¾›ã—ã¦ã„ã¾ã™ã€‚ ã“れã«ã‚ˆã‚Šã€é–‹ç™ºè€…ã¯è¤‡é›‘ãªã‚¿ã‚¹ã‚¯ã‚’ç°¡å˜ã«å‡¦ First of all, let's see how I set up my tool, model, agent, callback handler and AgentExecutor : Tool : from datetime import datetime from typing import Literal, Annotated Inside middleware You can access runtime information in middleware to create dynamic prompts, modify messages, or control agent behavior based on user context. tools import InjectedToolArg, tool from typing_extensions import Annotated user_to_pets = {} @tool(parse_docstring=True) def update_favorite_pets( pets: List[str], runtime is not passed to tool function if the args_schema is defined with Pydantic BaseModel · Issue #33646 · langchain-ai/langchain @dataclass class Context: """Custom runtime context schema.
