+#+TITLE: Delete Calendar Event Workflow
+#+AUTHOR: Craig Jennings & Claude
+#+DATE: 2026-02-01
+
+* Overview
+
+Workflow for deleting calendar events via gcalcli with explicit confirmation.
+
+* Triggers
+
+- "delete the meeting"
+- "cancel my appointment"
+- "remove the event"
+- "clear my calendar for..."
+
+* Prerequisites
+
+- gcalcli installed and authenticated
+- Event must exist on calendar
+
+* Note: Calendar Visibility
+
+Events can only be deleted from Google calendars via gcalcli. DeepSat (work) and Proton calendar events are visible in =~/.emacs.d/data/{dcal,pcal}.org= but cannot be modified from here.
+
+* Workflow Steps
+
+** 1. Parse User Request
+
+Extract:
+- Which event (title, partial match, or date hint)
+- Date context (if provided)
+
+Examples:
+- "Delete the dentist appointment" → search for "dentist"
+- "Cancel tomorrow's meeting" → search tomorrow's events
+- "Remove the 3pm call" → search by time
+
+** 2. Search for Event
+
+#+begin_src bash
+# Search by title
+gcalcli --calendar "Calendar Name" search "event title"
+
+# Or list events for a date
+gcalcli --calendar "Calendar Name" agenda "date" "date 11:59pm"
+#+end_src
+
+** 3. Handle Multiple Matches
+
+If search returns multiple events:
+
+#+begin_example
+Found 3 events matching "meeting":
+
+1. Team Meeting - Feb 3, 2026 at 9:00 AM
+2. Project Meeting - Feb 4, 2026 at 2:00 PM
+3. Client Meeting - Feb 5, 2026 at 10:00 AM
+
+Which event do you want to delete? (1-3)
+#+end_example
+
+** 4. Display Full Event Details
+
+Show the event that will be deleted:
+
+#+begin_example
+Event to Delete:
+================
+Event: Team Meeting
+When: Monday, Feb 3, 2026 at 9:00 AM
+Duration: 1 hour
+Location: Conference Room A
+Description: Weekly sync
+Calendar: Work
+#+end_example
+
+** 5. Explicit Confirmation
+
+Ask clearly:
+
+#+begin_example
+Delete this event? (yes/no)
+#+end_example
+
+*Do NOT delete until user explicitly confirms with "yes".*
+
+** 6. Execute Delete
+
+gcalcli delete requires interactive confirmation. Since Claude can't interact with the prompt, pipe "y" to confirm:
+
+#+begin_src bash
+echo "y" | gcalcli --calendar "Calendar Name" delete "Event Title"
+#+end_src
+
+Use a date range to narrow matches and avoid deleting the wrong event:
+
+#+begin_src bash
+echo "y" | gcalcli --calendar "Calendar Name" delete "Event Title" 2026-02-14 2026-02-15
+#+end_src
+
+** 7. Verify
+
+Confirm the event is gone:
+
+#+begin_src bash
+gcalcli --calendar "Calendar Name" search "Event Title"
+#+end_src
+
+Report success:
+
+#+begin_example
+Event "Team Meeting" has been deleted from your calendar.
+#+end_example
+
+* gcalcli Delete Command
+
+** Basic Delete (pipe confirmation)
+
+gcalcli delete prompts interactively, which fails in non-interactive shells. Always pipe "y" to confirm:
+
+#+begin_src bash
+echo "y" | gcalcli delete "Event Title"
+#+end_src
+
+** With Date Range (preferred — avoids accidental matches)
+
+#+begin_src bash
+echo "y" | gcalcli delete "Event Title" 2026-02-14 2026-02-15
+#+end_src
+
+** Calendar-Specific Delete
+
+#+begin_src bash
+echo "y" | gcalcli --calendar "Craig" delete "Meeting" 2026-02-14 2026-02-15
+#+end_src
+
+** Skip All Prompts (dangerous)
+
+#+begin_src bash
+gcalcli delete "Event Title" --iamaexpert
+#+end_src
+
+*Warning:* =--iamaexpert= skips all prompts and deletes every match. Avoid unless the search is guaranteed to match exactly one event.
+
+* Handling Multiple Events
+
+If the search pattern matches multiple events, gcalcli may:
+- Delete all matching events (dangerous!)
+- Prompt for each one (interactive mode)
+
+*Best practice:* Use specific titles or search first, then delete by exact match.
+
+* Recurring Events
+
+*Warning:* Deleting a recurring event deletes ALL instances.
+
+For recurring events:
+1. Warn the user that all instances will be deleted
+2. Ask for confirmation specifically mentioning "all occurrences"
+3. Consider if they only want to delete one instance (not supported by simple delete)
+
+#+begin_example
+This is a recurring event. Deleting it will remove ALL occurrences.
+
+Delete all instances of "Weekly Standup"? (yes/no)
+#+end_example
+
+* Error Handling
+
+** Event Not Found
+- Verify spelling
+- Try partial match
+- Check date range
+- May have already been deleted
+
+** Delete Failed
+- Check calendar permissions
+- Verify event exists
+- Try with --calendar flag
+
+** Wrong Event Deleted
+- Cannot undo gcalcli delete
+- Would need to recreate the event manually
+
+* Safety Considerations
+
+1. *Always show full event details* before asking for confirmation
+2. *Never delete without explicit "yes"* from user
+3. *Warn about recurring events* before deletion
+4. *Verify deletion* by searching after
+5. *Read-only calendars* (like Christine's) cannot have events deleted
+
+* Read-Only Calendars
+
+Some calendars are read-only:
+
+| Calendar                  | Can Delete? |
+|---------------------------+-------------|
+| Craig                     | Yes         |
+| Christine                 | Yes         |
+| Todoist                   | Yes         |
+| Craig Jennings (TripIt)   | No          |
+| Holidays in United States | No          |
+| Craig Proton              | No          |
+
+If user tries to delete from read-only calendar:
+
+#+begin_example
+Cannot delete from "Craig Proton" - this is a read-only calendar.
+#+end_example
