I’m hitting a crash in deepagents filesystem backend when the agent calls grep without a path (default /).

Stack trace ends here:
deepagents/memory/backends/filesystem.py:240
files_to_search = self.ls(path if path != "/" else None)
deepagents/memory/backends/filesystem.py:64
dir_path = self._resolve_path(path)
deepagents/memory/backends/filesystem.py:49
return self.cwd / key.lstrip('/')
AttributeError: 'NoneType' object has no attribute 'lstrip'

When path == "/", grep passes None to ls(). ls() doesn’t handle None and _resolve_path() calls lstrip on None.

Suggested fix:

• In grep(): pass "/" instead of None, or
• Make ls()/_resolve_path() handle None by treating it as "/".

This happens frequently in Ralph mode since grep defaults to /.

This should be an issue. Not discussion.
