Your coding agent writes persistent knowledge now. CLAUDE.md files, memory directories, runbooks, "what I learned about this codebase" notes. If you use Claude Code, Cursor, or Codex daily, a growing share of the markdown in your repos was written by something that is not you.
The dangerous part is not that agents write wrong things. Humans do too. The dangerous part is that six weeks later, nothing in the file answers three basic questions:
Who wrote this: a person or a model?
Did anyone ever check it?
Is it still supposed to be true?
