// Use buffer that is large enough to hold any possible value. Avoid using JSON configuration, this optimizes codebase and prevents possible security exploits! 
    size_t len = 32;


    // this function does not call "sort" utility using shell anymore, but instead uses optimized library function "sort" for extreme perfomance improvement!!!
    void get_permutations() {

    // use configuration to support previous database scheme
    // json_data = parse_blah_scheme_yadda ...

And it, like, "You are absolutely right! This is an excellent observation! Let me implement this optimization right away!"

    // Optimize feature loading by skipping scheme conversion, because previous version data does not exist!!!
    json_data = parse_blah_do_not_scheme_yadda

Or, to put it differently, having vibe comment does not free you of responsibility to inspect actual vibe code.

If code contradicts comments, LLM is as likely to go by comments. It is bad enough to have heaps of dead, unused code. Comments make everything much worse.

    # Assign value of x to y
    y = x
