porteden

Use porteden for calendar management across multiple accounts. Use -jc flags for AI-optimized output.

If porteden is not installed: brew install porteden/tap/porteden (or go install github.com/porteden/cli/cmd/porteden@latest).

Setup (once)

  • Browser login (recommended): porteden auth login — opens browser, credentials stored in system keyring
  • Direct token: porteden auth login --token <key> — stored in system keyring
  • Verify: porteden auth status
  • If PE_API_KEY is set in the environment, the CLI uses it automatically (no login needed).

Common commands

  • List calendars: porteden calendar calendars -jc
  • Events today (or --tomorrow, --week): porteden calendar events --today -jc
  • Events custom range: porteden calendar events --from 2026-02-01 --to 2026-02-07 -jc
  • All events (auto-pagination): porteden calendar events --week --all -jc
  • Search events: porteden calendar events -q "meeting" --today -jc
  • Events by contact: porteden calendar by-contact "user@example.com" -jc (or --name "John Smith")
  • Get single event: porteden calendar event <eventId> -jc
  • Create event: porteden calendar create --calendar <id> --summary "Meeting" --from "..." --to "..." --location "Room A" --attendees "a@b.com,c@d.com"
  • Update event: porteden calendar update <eventId> --summary "New Title" (also: --from, --to, --location)
  • Update attendees: porteden calendar update <eventId> --add-attendees "new@example.com" (or --remove-attendees; add --notify to send notifications)
  • Delete event: porteden calendar delete <eventId> (add --no-notify to skip attendee notifications)
  • Respond to invite: porteden calendar respond <eventId> accepted (or: declined, tentative)

Event Status Values

  • confirmed - Accepted/scheduled
  • tentative - Maybe attending
  • needsAction - Requires response from user
  • cancelled - Event was cancelled

Time Formats

  • All times use RFC3339 UTC format: 2026-02-01T10:00:00Z
  • For all-day events, use midnight-to-midnight with --all-day flag
  • JSON output includes startUtc, endUtc, durationMinutes fields

Notes

  • Credentials persist in the system keyring after login. No repeated auth needed.
  • Set PE_PROFILE=work to avoid repeating --profile.
  • -jc is shorthand for --json --compact: filters noise, truncates descriptions, limits attendees, reduces tokens.
  • Use --all to auto-fetch all pages; check meta.hasMore and meta.totalCount in JSON output.
  • Manual pagination: --limit 100 --offset 0, then --offset 100, etc.
  • by-contact supports partial matching: "@acme.com" for email domain, --name "Smith" for name.
  • Confirm before creating, updating, or deleting events.
  • "invalid calendar ID": Get IDs with porteden calendar calendars -jc.
  • Environment variables: PE_API_KEY, PE_PROFILE, PE_TIMEZONE, PE_FORMAT, PE_COLOR, PE_VERBOSE.
What it does

The capability, in one paragraph

PortEden Calendar fronts both Google Calendar and Microsoft 365 calendars behind one command. The agent writes `porteden calendar events --today` and gets the same JSON shape regardless of which backend the profile points at. The skill covers the full event lifecycle — list, search by date or contact, create, update, delete, respond to invitations (accepted/declined/tentative), and propose new times. Attendee email addresses, location strings, and meeting body content all run through PortEden's redaction policy before they reach the agent context.
Why it matters

Calendars are dense with PII you wouldn't paste into ChatGPT on purpose: attendee identities, location strings that double as office addresses or hospital wards, meeting bodies that contain client names and case numbers. PortEden Calendar lets the agent triage and schedule without the body content ever leaving your network in plaintext.

How it works

A few flags, predictable output

01

Cross-backend normalization

Google Calendar resourceIds and Microsoft Graph eventIds are wrapped in PortEden's google: / microsoft: prefix scheme. Commands work on either with no agent-side branching.

02

Date-aware filters

--today, --this-week, --next-week, --since, and --until are time-zone aware (PE_TIMEZONE). RFC3339 UTC strings always work as the explicit fallback.

porteden calendar events --today -jc
porteden calendar events --since 2025-12-01T00:00:00Z --until 2025-12-31T23:59:59Z -jc
03

Attendee-based search

events search --contact <email> returns every event involving that attendee across all calendars in the profile — useful for triaging recurring meetings or rescheduling around a vacation.

Install

Five minutes, three commands

1

Install the PortEden CLI

Grok Build skills delegate every API call to the porteden binary. Install once with Homebrew or Go — the agent runtime invokes it on your behalf.

brew install porteden/tap/porteden
# or
go install github.com/porteden/cli/cmd/porteden@latest
2

Authenticate

Browser-based login is recommended — credentials are written to your OS keyring. Token-based login is available for headless environments.

porteden auth login
# headless / CI
porteden auth login --token <PE_API_KEY>
porteden auth status
3

Add porteden-calendar to your Grok Build skills directory

Grok Build loads SKILL.md files from .grok/skills/. Drop the canonical SKILL.md into that directory and Grok picks it up on next session.

mkdir -p .grok/skills/porteden-calendar
curl -fsSL https://porteden.com/skills/grok-build/porteden-calendar/SKILL.md \
-o .grok/skills/porteden-calendar/SKILL.md
