Implementation Reference
- The core handler function that executes the linear_assignIssue tool. Validates input with isAssignIssueArgs type guard and delegates to LinearService.assignIssue.
export function handleAssignIssue(linearService: LinearService) { return async (args: unknown) => { try { if (!isAssignIssueArgs(args)) { throw new Error("Invalid arguments for assignIssue"); } return await linearService.assignIssue(args.issueId, args.assigneeId); } catch (error) { logError("Error assigning issue", error); throw error; } }; } - The MCP tool definition (schema) for linear_assignIssue, including input and output schemas.
