› write hello.txt


• I'll follow my instructions and check relevant docs before writing hello.txt. Since there aren't specific guidelines for this file,
  it feels like a good call to create it with the simple content "hello". I’ll go ahead and create it in the workspace root, using the
  apply_patch method.

• Added hello.txt (+1 -0)
    1 +hello

✘ Failed to apply patch
  └ failed in sandbox

• It seems like I'm facing an issue with apply_patch—maybe the sandbox restricts its use. While typically I wouldn’t need a working
  directory for this command, the error suggests it's not permitted in this environment. A viable alternative might be to create a file
  using a shell command instead. I’m thinking of executing something like ["bash","-lc","printf 'hello\n' > hello.txt"] to get around
  this!

• Ran printf 'hello
  │ ' > hello.txt
  └ failed in sandbox

What steps can reproduce the bug?

run
codex --sandbox workspace-write --ask-for-approval never

then ask it to write a file

What is the expected behavior?

it should write the file.
