Description

When file operations (read_file, write_file, edit_file) access paths outside WORKDIR, the permission check correctly returns:
Path escapes workspace
However, the agent bypasses the restriction by switching to the bash tool to directly access files outside the workspace.
The current permission mechanism only validates individual file tools and does not prevent equivalent operations through other tools.

Research direction

Start by tracing permission checks for read_file, write_file, edit_file, and the bash tool, focusing on how WORKDIR boundaries are enforced. Verify that equivalent bash file operations cannot escape WORKDIR, then exercise both the file tools and bash path cases to confirm the restriction is consistent.
