Google Sheets

<!-- Generated by scripts/gen-agent-skills.mjs; do not edit. -->

Use gog for Google Sheets operations. Read ../gog/SKILL.md first for shared auth, output, safety, and live-write rules.

Safe start

gog auth list --check --json --no-input
gog schema sheets --json
gog --readonly --account user@example.com sheets get SHEET_ID 'Sheet1!A1:D20' --json --wrap-untrusted

• Select the account explicitly with --account.
• Use --json --wrap-untrusted for agent-readable Google content.
• Use --readonly when the task must not mutate Google data.
• Use --no-input in automation and --dry-run before supported writes.
• Confirm the exact account, object, and mutation before any write or delete.
