Desktop Auto-review rejects 79,785-byte Google Drive batch update as over 200,000-byte review limit

On 2026-09-17, Codex desktop on macOS rejected a user-authorized google_drive.batch_update_spreadsheet call before execution with Guardian action exceeds the 200000-byte review limit. The tool arguments measured 79,785 UTF-8 bytes. The call would add one tab, write a header and 365 date rows, and set validation and formatting. The tool record showed failure at 0 ms; a metadata read confirmed no tab was created.

We cannot determine the size or composition of the full Auto-review input. Please clarify how this limit is measured, whether the documented /approve flow or an equivalent desktop flow applies to this failure, and the supported way to complete the reviewed operation. This differs from #44808, where the tool arguments themselves exceeded 200,000 bytes. No split or indirect retry has been attempted.

No spreadsheet ID, private project details, request payload, or logs are included.

Start by tracing the Auto-review handling for google_drive.batch_update_spreadsheet and the 200000-byte review limit, then inspect how the documented /approve flow applies to this failure. Verify how the input size is measured and identify the supported desktop completion path; done means the behavior and resolution are documented or corrected.
