What

Claude Code's file tools, as used in a remote sandbox (an isolated environment where commands run), behave more strictly:

  • write and edit: refuse any path inside a read-only folder, saying it "is inside read-only directory".
  • read: accepts view_range for files over the size limit, instead of only telling you to use Bash to read a slice.
  • glob: always rejects absolute patterns and asks for a relative one, even where they were allowed before, and caps how many files it scans.
Why

These tools are harder to use against folders or paths they should not touch.
