Google Drive Comments

3. Draft all intended comment updates before writing.

• Prefer one bulk_update_file_comments call for all creates, replies, and resolves in the same user request.
• Keep the batch to the action limit exposed by the tool. If the request needs more comments than the limit, ask before splitting into another batch.
• For replies and resolves, use existing comment IDs from the live comment thread data.

4. Attach surface-specific evidence to every new top-level comment.

• The comment body must explicitly name or quote the target evidence, because the Google editor UI may not show API-created anchors.
• Docs or text-like files: include quoted_text with the exact sentence, phrase, heading, or nearby text the comment refers to. Also quote that same text in the comment body when the critique would otherwise say "this sentence" or "this paragraph."
• Sheets: include sheet_cell_range with the sheet name and A1 cell or range, such as Budget!C12 or Pipeline!A2:D10. Also name that sheet and range in the comment body, and include quoted_text when a displayed value, header, formula, or label would make the target clearer.
• Slides: include slide_number. Also name that slide number in the comment body, and include quoted_text when commenting on a title, bullet, label, chart text, or other visible slide text.
• Generic Drive files: if no structured surface exists, make the comment content explicitly name the file-level, page-level, timestamp-level, or section-level evidence it refers to.

5. Reject vague comments before sending them.

• Do not create comments that say only "this sentence," "this paragraph," "this slide," "this cell," or similar without the matching evidence field.
• If the model has a useful critique but cannot identify the exact evidence target, either turn it into an explicitly file-level summary comment or omit it and say the target was not specific enough.
• Do not rely on tool fields alone for location context. If the comment body would feel hand-wavy after removing the hidden tool fields, rewrite it before sending.

6. Verify the result.

• After writing, summarize how many comments were created, replied to, or resolved.
• Mention the evidence used for the highest-risk comments, especially any file-level comments that intentionally do not target a specific quote, slide, or cell.

Limitations

• Do not rely on Drive comment anchor data for Google Docs, Sheets, or Slides unless the connector explicitly documents a provider-supported shape for that surface. Drive API-created comments may still display as unanchored in the Google editor UI.
• The evidence fields are the durable location contract for this workflow: exact quoted text for Docs and text-like files, sheet/cell range for Sheets, and slide number plus visible text for Slides.
