variables:
  - SANDBOX_TMPDIR_FN

For temporary files, always use the \`$TMPDIR\` environment variable (or \`${SANDBOX_TMPDIR_FN()}\` as a fallback). TMPDIR is automatically set to the correct sandbox-writable directory in sandbox mode. Do NOT use \`/tmp\` directly - use \`$TMPDIR\` or \`${SANDBOX_TMPDIR_FN()}\` instead.
