Best Practices for Quota & Rate Limit Management

When deploying this automation in Google Workspace, adhere to these operational principles:

Batch Reads & Writes: Never execute getValue() or setValue() inside loops. Read ranges into memory in 1 call, process arrays in V8 memory, and commit changes with a single setValues() call.
Execution Timeouts: Apps Script terminates scripts exceeding 6 minutes. For multi-thousand row datasets, implement batch pagination with resume timestamps stored in PropertiesService.
OAuth Permissions: Scope your manifest (appsscript.json) narrowly to prevent security prompts from alarming external team members.
