Implementation Reference
- src/tools/TaskFlowTools.ts:595-598 (handler)The MCP tool handler function for 'delete_task' that extracts requestId and taskId from arguments and delegates to TaskFlowService.deleteTask.
async delete_task(args: any) { const { requestId, taskId } = args ?? {}; return service.deleteTask(String(requestId), String(taskId)); }, - Core implementation in TaskFlowService: loads task data, verifies request and task exist and task not done, removes task from array, saves file, generates progress table.
public async deleteTask(requestId: string, taskId: string) { await this.loadTasks(); const req = this.getRequest(requestId); if (!req) return { status: "error", message: "Request not found" }; const taskIndex = req.tasks.findIndex((t) => t.id === taskId); if (taskIndex === -1) return { status: "error", message: "Task not found" }; if (req.tasks[taskIndex].done) return { status: "error", message: "Cannot delete completed task" }; req.tasks.splice(taskIndex, 1); await this.saveTasks(); const progressTable = formatTaskProgressTableForRequest(req); return { status: "task_deleted", message: `Task ${taskId} has been deleted.\n${progressTable}` }; } - JSON Schema definition for delete_task input parameters: requires requestId and taskId.
delete_task: { type: "object", properties: { requestId: { type: "string" }, taskId: { type: "string" }, }, required: ["requestId", "taskId"], }, - src/tools/TaskFlowTools.ts:221-234 (registration)Tool metadata registration: defines name, description, and inputSchema for the delete_task tool.
