Agent Discovery Failure: Generated Agents Not Recognized or Loadable

Bug Description
Suddenly Claude Code will not recognize agents. I can have it generate a test agent. It will create the file, but it will not show up in /agents and it will not be usable. I've tried clearing all the files, uninstall, reinstall, local and global, different versions. Everything short of an os reinstall. Nothing helps.
