Claude Code memory helps the AI remember context within its own sessions. But it’s still one model’s view of what “should” be consistent. VibeDrift doesn’t rely on any AI’s memory or opinion. It looks at the code that actually exists in your repo and measures what the majority of files do vs which files break from that pattern. It’s also deterministic, meaning same codebase, same score every time, which matters if you want to track drift over time or gate PRs in CI.
