Apple Calendar Ops

Read, create, update, and delete Apple Calendar events via CalDAV. Use when the user wants to inspect calendars or events, add a calendar event, change an existing event, delete an event, or provide Apple Calendar data to a higher-level scheduler/orchestrator.

This skill is the Apple Calendar operation layer.

It handles stable calendar reads and writes. It does not do high-level scheduling, cross-system planning, or task prioritization.

Core boundary

Use this skill for concrete Apple Calendar operations:

• list calendars
• fetch events in a time range
• create an event
• update an event
• delete an event

Do not use this skill to decide how the day should be planned. That belongs to a higher-level task/orchestrator.

Operating rules

Default stance:

• reads are safe
• writes should be dry-run-friendly
• updates/deletes should prefer explicit event ids
• fuzzy title matching may help locate events, but should not be the only basis for risky writes

Credentials should come from /home/agent/.openclaw/workspace/secrets.json.

Read references/boundary.md before changing the skill's scope. Read references/event-contract.md before writing or consuming event JSON.

Quick start

Read calendars

bash

python3 /home/agent/.openclaw/workspace/skills/apple-calendar-ops/scripts/calendar_fetch.py --list-calendars

Read events

bash

python3 /home/agent/.openclaw/workspace/skills/apple-calendar-ops/scripts/calendar_fetch.py \
  --start 2026-03-12T00:00:00+08:00 \
  --end 2026-03-13T00:00:00+08:00

Create event

bash

python3 /home/agent/.openclaw/workspace/skills/apple-calendar-ops/scripts/calendar_create.py \
  --calendar "Calendar" \
  --title "Example event" \
  --start 2026-03-12T14:00:00+08:00 \
  --end 2026-03-12T15:00:00+08:00 \
  --dry-run

Scripts

• scripts/calendar_common.py — shared config, secret loading, and JSON helpers
• scripts/calendar_fetch.py — list calendars and fetch events
• scripts/calendar_create.py — create an event
• scripts/calendar_update.py — update an event
• scripts/calendar_delete.py — delete an event

References

• references/boundary.md — scope and non-goals
• references/event-contract.md — normalized event shape for all scripts

First-version goal

Version 1 should make Apple Calendar readable and safely writable.

That means:

• reliable read access for scheduler inputs
• explicit create/update/delete flows
• machine-readable output
• conservative handling of risky writes
