If you say "AI tools", some vibe-coders try to equivocate between tools that generate the whole program for you and, like, an editor that uses an scoring algorithm to decide which method to show at the top of an autocomplete list. But if you say "vibe coding", some vibe-coders try to claim that what they're doing technically isn't vibe coding because they applied some non-zero amount of testing or review during the process.

If you ask "did you build this using Codex or Claude", it removes most of the wiggle room. And it's worded pretty neutrally, so it will often get vibe-coders who aren't technically using either of those tools to say something like, "Actually, I've built a custom harness for DeepSeek..." instead of an outright denial.
