Gws Apps Script

Security checks for vulnerabilities and agentic risk

Overview

This skill is a concise Google Apps Script CLI reference with expected project management powers, including a clearly mentioned overwrite operation users should handle carefully.

Install only if you intend to let an agent operate your Google Apps Script projects through `gws`. Treat `projects.updateContent` as an overwrite operation: confirm the target project and keep a backup or source-controlled copy before using it.
