Gog Calendar

gog-calendar

Use gog (gogcli) for Google Calendar: agenda (events list) and keyword search across calendars.

Output rule (tokens vs reliability)

gogcli stdout should stay parseable; prefer --plain / --json and put hints to stderr. oai_citation:0‡GitHub

• Default to --plain for read-only listing you only summarize (cheaper tokens):
  • agenda listing (today / next days / range)
  • calendars list
• Use --json only when structure is required:
  • aggregating results across calendars (cross-calendar keyword search)
  • deduping / sorting / extracting IDs for follow-up calls
  • any write workflow where exact fields matter
• In automation runs, add --no-input (fail instead of prompting). oai_citation:1‡GitHub

Calendar exclusions (post-processing)

Users may explicitly exclude certain calendars from searches/agenda (e.g., “National holidays”).
When answering, you MUST:

1. Query broadly (e.g., events --all or iterate all calendars for search),
2. Then filter out excluded calendars in post-processing.

How to determine excluded calendars:

• First, check the user’s preferences/memory for an explicit “exclude calendars” list.
• If none is provided, apply a conservative default filter for obvious noise calendars:
  • calendars whose name/summary contains: holiday, holidays, national holidays (and localized equivalents)
• Never filter out user-owned calendars unless explicitly excluded.

Filtering rule:

• If you have calendar metadata (from gog calendar calendars), filter by calendar name/summary.
• If you only have events output, filter by matching event’s calendarId to the excluded calendarIds resolved from the calendars list.

Always mention filtering briefly if it materially changes the answer:

• “(Filtered out: National holidays)”

Agenda (always cross-calendar, then filter)

For “what’s on my calendar today / tomorrow / this week / between X and Y”:

• MUST query all calendars:
  • gog calendar events --all --from <date_or_iso> --to <date_or_iso> --plain
• Then apply calendar exclusions (above).
• Do not answer “nothing scheduled” unless you ran the command for the correct window and applied filtering.

Examples:

• Today: gog calendar events --all --from 2026-02-04 --to 2026-02-05 --plain
• Next 7 days: gog calendar events --all --from 2026-02-04 --to 2026-02-11 --plain

Output formatting:

• sort by start time
• group by day
• show: time range, summary, location (calendar name only if it helps)

Keyword search across calendars (best-effort, aggregate, then filter)

Calendar event queries are scoped to a calendarId (API is /calendars/{calendarId}/events), so keyword search must iterate calendars and aggregate results. oai_citation:2‡Google for Developers

Default window:

• if user didn’t specify a range: next 6 months from today (inclusive)
• if user specified date/range: use it

Workflow (do not skip):

1. List calendars (need IDs + names for filtering):
   • gog calendar calendars --json
2. Build the set of excluded calendarIds from the exclusions rule.
3. For EACH non-excluded calendarId, search (JSON required for merge/dedupe):
   • gog calendar search "<query>" --calendar <calendarId> --from <from> --to <to> --max 50 --json --no-input
4. Aggregate all matches across calendars (do NOT stop on first match unless user asked).
5. Deduplicate by (calendarId, eventId), sort by start time.
6. Report results and explicitly mention the searched window (and any filters applied).

If nothing found in default window:

• say: “No events found in the next 6 months ( → ). Want me to search further (e.g., 12 months) or within specific dates?”

Fallback if user is sure it exists:

• ask/derive an approximate date and list around it (then filter):
  • gog calendar events --all --from <date-7d> --to <date+7d> --plain
• then match by title tokens locally (casefold + token overlap)

Writes (create/update/delete/RSVP)

Before any write action:

• summarize exact intent (calendar, title, start/end, timezone, attendees, location)
• ask for explicit “yes”
• then run the command
