Auto insert snippet skel for empty or new files

Lua
1

Using templastes is boring because templates are static, I would like to be able to trigger a _skel snippet for new/ampty files.
I am having some issues but I would like receive some feedback

-- Define local variables
local augroup = vim.api.nvim_create_augroup
local autocmd = vim.api.nvim_create_autocmd

augroup("AutoSkel", { clear = true })
autocmd("BufEnter", {
  group = "AutoSkel",
  pattern = "*.lua",
  callback = function()
    if vim.fn.line("$") ~= 1 or vim.fn.getline(1) ~= "" then
      return
    end
    local snips = require("luasnip").get_snippets()[vim.bo.ft]
    for _, snip in ipairs(snips) do
      vim.cmd('startinsert')
      if snip["name"] == "_skel" then
        require("luasnip").snip_expand(snip)
        return true
      end
    end
  end,
})
