gog is a comprehensive, production-grade CLI tool for Google Workspace automation that unifies 20+ Google services (Gmail, Calendar, Drive, Docs, Sheets, Slides, Forms, Meet, Chat, Contacts, Tasks, Classroom, YouTube, Analytics, Search Console, Admin, Groups, Keep, Photos, Maps, Apps Script) into a single binary. It excels at task-first workflows: searching and sanitizing mail, resolving calendar names, auditing Drive sharing, editing Docs, appending Sheet tables, building Slides from Markdown, managing Workspace users, and performing encrypted backups. The architecture is a modular monolith with clean internal package boundaries for each service domain. Key entry points are cmd/gog/main.go and the Kong-based command tree in internal/cmd. Primary data flows: command invocation -> account/client resolution -> authenticated Google API client creation -> API execution -> structured output (JSON, plain TSV, or human-readable tables). External dependencies include Google APIs, OAuth2, keyring backends (macOS Keychain, Windows Credential Manager, Linux Secret Service, encrypted file), MCP for agent integration, and age encryption for backups. The codebase demonstrates exceptional craftsmanship in cross-platform secret storage, Gmail push notification processing, sed-style Docs editing with UTF-16 index tracking, atomic Docs request batching, encrypted backup with Git shard checkpointing, email open tracking with versioned key rotation and bot detection, and build-time safety profile compilation to hash-based allow/deny switches. Active development with recent commits, comprehensive test coverage (unit + integration + live tests), and modern dependency versions.
