It enables selective approval workflows where certain tools\n * require human intervention while others can execute automatically.\n *\n * A invocation result that has been interrupted by the middleware will have a `__interrupt__`\n * property that contains the interrupt request.\n *\n * ```ts\n * import { type HITLRequest, type HITLResponse } from \"langchain\";\n * import { type Interrupt } from \"langchain\";\n *\n * const result = await agent.invoke(request);\n * const interruptRequest = result.__interrupt__?.[0] as Interrupt<HITLRequest>;\n *\n * // Examine the action requests and review configs\n * const actionRequests = interruptRequest.value.actionRequests;\n * const reviewConfigs = interruptRequest.value.reviewConfigs;\n *\n * // Create decisions for each action\n * const resume: HITLResponse = {\n *   decisions: actionRequests.map((action, i) => {\n *     if (action.name === \"calculator\") {\n *       return { type: \"approve\" };\n *     } else if (action.name === \"write_file\") {\n *       return {\n *         type: \"edit\",\n *         editedAction: { name: \"write_file\", args: { filename: \"safe.txt\", content: \"Safe content\" } }\n *       };\n *     }\n *     return { type: \"reject\", message: \"Action not allowed\" };\n *   })\n * };\n *\n * // Resume with decisions\n * await agent.invoke(new Command({ resume }), config);\n * ```\n *\n * ## Features\n *\n * - **Selective Tool Approval**: Configure which tools require human approval\n * - **Multiple Decision Types**: Approve, edit, or reject tool calls\n * - **Asynchronous Workflow**: Uses LangGraph's interrupt mechanism for non-blocking approval\n * - **Custom Approval Messages**: Provide context-specific descriptions for approval requests\n *\n * ## Decision Types\n *\n * When a tool requires approval, the human operator can respond with:\n * - `approve`: Execute the tool with original arguments\n * - `edit`: Modify the tool name and/or arguments before execution\n * - `reject`: Provide a manual response instead of executing the tool\n *\n * @param options - Configuration options for the middleware\n * @param options.interruptOn - Per-tool configuration mapping tool names to their settings\n * @param options.interruptOn[toolName].allowedDecisions - Array of decision types allowed for this tool (e.g., [\"approve\", \"edit\", \"reject\"])\n * @param options.interruptOn[toolName].description - Custom approval message for the tool. Can be either a static string or a callable that dynamically generates the description based on agent state, runtime, and tool call information\n * @param options.interruptOn[toolName].argsSchema - JSON schema for the arguments associated with the action, if edits are allowed\n * @param options.descriptionPrefix - Default prefix for approval messages (default: \"Tool execution requires approval\"). Only used for tools that do not define a custom `description` in their InterruptOnConfig.\n *\n * @returns A middleware instance that can be passed to `createAgent`\n *\n * @example\n * Basic usage with selective tool approval\n * ```typescript\n * import { humanInTheLoopMiddleware } from \"langchain\";\n * import { createAgent } from \"langchain\";\n *\n * const hitlMiddleware = humanInTheLoopMiddleware({\n *   interruptOn: {\n *     // Interrupt write_file tool and allow edits or approvals\n *     \"write_file\": {\n *       allowedDecisions: [\"approve\", \"edit\"],\n *       description: \"⚠️ File write operation requires approval\"\n *     },\n *     // Auto-approve read_file tool\n *     \"read_file\": false\n *   }\n * });\n *\n * const agent = createAgent({\n *   model: \"openai:gpt-4\",\n *   tools: [writeFileTool, readFileTool],\n *   middleware: [hitlMiddleware]\n * });\n * ```\n *\n * @example\n * Handling approval requests\n * ```typescript\n * import { type HITLRequest, type HITLResponse, type Interrupt } from \"langchain\";\n * import { Command } from \"@langchain/langgraph\";\n *\n * // Initial agent invocation\n * const result = await agent.invoke({\n *   messages: [new HumanMessage(\"Write 'Hello' to output.txt\")]\n * }, config);\n *\n * // Check if agent is paused for approval\n * if (result.__interrupt__) {\n *   const interruptRequest = result.__interrupt__?.[0] as Interrupt<HITLRequest>;\n *\n *   // Show tool call details to user\n *   console.log(\"Actions:\", interruptRequest.value.actionRequests);\n *   console.log(\"Review configs:\", interruptRequest.value.reviewConfigs);\n *\n *   // Resume with approval\n *   const resume: HITLResponse = {\n *     decisions: [{ type: \"approve\" }]\n *   };\n *   await agent.invoke(\n *     new Command({ resume }),\n *     config\n *   );\n * }\n * ```\n *\n * @example\n * Different decision types\n * ```typescript\n * import { type HITLResponse } from \"langchain\";\n *\n * // Approve the tool call as-is\n * const resume: HITLResponse = {\n *   decisions: [{ type: \"approve\" }]\n * };\n *\n * // Edit the tool arguments\n * const resume: HITLResponse = {\n *   decisions: [{\n *     type: \"edit\",\n *     editedAction: { name: \"write_file\", args: { filename: \"safe.txt\", content: \"Modified\" } }\n *   }]\n * };\n *\n * // Reject with feedback\n * const resume: HITLResponse = {\n *   decisions: [{\n *     type: \"reject\",\n *     message: \"File operation not allowed in demo mode\"\n *   }]\n * };\n * ```\n *\n * @example\n * Production use case with database operations\n * ```typescript\n * const hitlMiddleware = humanInTheLoopMiddleware({\n *   interruptOn: {\n *     \"execute_sql\": {\n *       allowedDecisions: [\"approve\", \"edit\", \"reject\"],\n *       description: \"🚨 SQL query requires DBA approval\\nPlease review for safety and performance\"\n *     },\n *     \"read_schema\": false,  // Reading metadata is safe\n *     \"delete_records\": {\n *       allowedDecisions: [\"approve\", \"reject\"],\n *       description: \"⛔ DESTRUCTIVE OPERATION -
