I tried vibe coding a BMP decoder not too long ago with the rationale being “what’s simpler than BMP?”

What I got was an absolute mess that did not work at all. Perhaps this was because, in retrospect, BMP is not actually all that simple, a fact that I discovered when I did write a BMP decoder by hand. But I spent equal time vibe coding and real coding. At the end of the real coding session, I understood BMP, which I see as a benefit unto itself. This is perhaps a bit cynical but my hot take on vibe coders is that they place little value on understanding things.

Mind explaining the process you tried? As someone who’s generally not had any issue getting LLMs to sort out my side projects (ofc with my active involvement as well), I really wonder what people who report these results are trying. Did you just open a chat with claude code and try to get a single context window to one shot it?

Just out of curiousity (as someone fairly familiar with the BMP spec, and also PNG incidentally): what did you find to be the trickiest/most complex aspects?
