GroundEffect
Use this skill when the user asks about email, calendar, or Gmail/Google Calendar management via GroundEffect CLI. Triggers include "search my email", "list recent emails", "check my calendar", "what's on my calendar", "show my meetings", "calendar tomorrow", "calendar next week", "create a calendar event", "manage groundeffect accounts", "sync status", "start the daemon", "groundeffect", "groundeffect command", "draft email", "save draft", "save as draft", "create draft", "send email".
Best use case
GroundEffect is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

# GroundEffect CLI GroundEffect provides local-first email and calendar management with semantic search capabilities. All data is synced locally and searchable offline. ## Quick Reference ### Email Commands ```bash groundeffect email search "query" # Search emails with natural language groundeffect email list # List recent emails groundeffect email show <id> # Show single email groundeffect email thread <thread_id> # Show email thread groundeffect email send --to X --subject "X" --body "X" # Send email groundeffect email send --to X --subject "X" --body "X" --html # Send HTML email groundeffect email send --to X --subject "X" --body "X" --save-as-draft # Save as draft groundeffect email attachment <email_id> <filename> # Get attachment groundeffect email folders # List IMAP folders ``` ### Draft Commands ```bash groundeffect email draft create --from X --to X --subject "X" --body "X" # Create draft groundeffect email draft create --from X --to X --subject "X" --body "X" --reply-to <email_id> # Reply draft groundeffect email draft list --from X # List drafts groundeffect email draft show --from X --draft-id <id> # Show draft groundeffect email draft update --from X --draft-id <id> --body "X" # Update draft groundeffect email draft send --from X --draft-id <id> # Send draft groundeffect email draft delete --from X --draft-id <id> # Delete draft ``` ### Calendar Commands ```bash groundeffect calendar events # List events by date range (no query needed) groundeffect calendar events --from 2026-01-07 --to 2026-01-08 --human # Tomorrow's events groundeffect calendar search "query" # Search events with semantic search groundeffect calendar list # List calendars groundeffect calendar show <event_id> # Show event details groundeffect calendar create --summary "X" --start "ISO" --end "ISO" # Create event ``` **Calendar Events vs Calendar Search**: - Use `calendar events` when the user asks "what's on my calendar tomorrow/next week" (date-based, no query) - Use `calendar search` when the user asks "find meetings about project X" (semantic search) ### Account Commands ```bash groundeffect account list # List all accounts groundeffect account show <email|alias> # Show account details groundeffect account add # Add new Google account groundeffect account delete <email|alias> # Remove account groundeffect account configure <email|alias> # Update settings ``` ### Sync Commands ```bash groundeffect sync status # Check sync status groundeffect sync reset <email|alias> # Reset synced data groundeffect sync extend <email|alias> # Sync older emails groundeffect sync download-attachments <email|alias> # Download pending attachments ``` ### Daemon Commands ```bash groundeffect daemon install # Install launchd daemon (auto-start at login) groundeffect daemon uninstall # Remove launchd daemon groundeffect daemon status # Check if daemon running groundeffect daemon restart # Restart daemon ``` ### Config Commands ```bash groundeffect config settings # View/modify daemon settings groundeffect config add-permissions # Add Claude Code permissions groundeffect config remove-permissions # Remove Claude Code permissions ``` ## Important Guidelines **DRAFTS**: When the user asks to "save as draft", "draft an email", or "save this draft", ALWAYS use the `groundeffect email draft create` command to save it to Gmail drafts. Do NOT save email drafts to markdown files - use Gmail's native draft system so the user can access, edit, and send drafts from any device. **SENDING**: When composing an email, use `groundeffect email send --save-as-draft` to save to Gmail drafts, or add `--confirm` to send immediately. Without these flags, the command returns a preview. ## Usage Notes - **CLI binary**: `groundeffect` - **Output format**: JSON by default, use `--human` for readable output - **Date format**: Use YYYY-MM-DD for date parameters - **Account references**: Use email address or alias interchangeably - **Help**: Add `--help` to any command for detailed options ## Detailed Documentation For complete command documentation with all flags and examples, read the appropriate reference file: - **Email**: `references/email-commands.md` - search, list, show, thread, send (HTML support), attachment, folders, drafts - **Calendar**: `references/calendar-commands.md` - search, list, show, create - **Accounts**: `references/account-commands.md` - list, show, add, delete, configure - **Sync**: `references/sync-commands.md` - status, reset, extend, download-attachments - **Daemon**: `references/daemon-commands.md` - install, uninstall, status, restart - **Config**: `references/config-commands.md` - settings, add-permissions, remove-permissions ## Common Workflows See `examples/common-workflows.md` for step-by-step usage patterns.
