Most of the time, maybe. Absolutely not always. I'll tell it to "implement feature a, ignore typescript errors". And it happened multiple times for me that it did the exact opposite, fix TS errors, and feature is barely mentioned in the response. Or more recently (with deep research) "Give me list of {some_product_name}, make absolutely sure to make a CSV and output a CSV. Columns are a,b,c,..". Does it give me the data? No, I get a wall of text with absolutely no data. Ok, you may argue this is some agent, etc. but user may not see a difference.
Don't take me wrong, I'm a big fan and constant user of all these things, but I would say it frequently have problem following prompts.
Or reduce complexity: https://xkcd.com/221/
I cannot count how many times that or something like that has happened to me.
