- Manage local or remote ICS calendar sources to inspect upcoming meetings, summarize work hours, and add, update, or delete calendar events when users need a quick operational view of their schedule.
ICS Manager
Read or edit .ics files from a local path or HTTP(S) URL.
Setup (one-time only)
uv run scripts/check_dependencies.py --install
# Set ICS_SOURCE and optional ICS_RANGE_START/ICS_RANGE_DAYS in .env or ~/.config/ics-manager/.env
Do NOT run
check_dependencies.pyon every invocation.uv runresolves dependencies automatically. Only run it once during initial setup or when the environment may be broken.
Commands
All operations go through scripts/ics_manager.py:
| Command | Key flags | Notes |
|---|---|---|
| list-events | --source (repeatable), --start, --end, --contains, --format json | Default window: active configured range, else 14 days |
| summarize-hours | --source (repeatable), --group-by day\|week, --contains | Aggregates event durations across all sources |
| overview | --source (repeatable), --start, --end, --contains, --format json | Count, total hours, busiest day, per-source counts — use this instead of combining list-events + summarize-hours |
| add-event | --source, --summary, --start, --end | Local files only |
| update-event | --source, --uid, --summary | Local files only |
| delete-event | --source, --uid | Local files only; .bak backup written by default |
Remote URLs are read-only. Use --uid for update/delete.
ICS_SOURCE can contain multiple calendars separated by commas or new lines. You can also repeat --source on read commands:
uv run scripts/ics_manager.py overview \
--source ~/calendar/work.ics \
--source ~/calendar/team.ics
To make Scrum check-ins default to the current sprint window, set these once in .env:
ICS_RANGE_START=2026-05-01
ICS_RANGE_DAYS=14
With that configuration, list-events, overview, and summarize-hours automatically use the active 14-day window starting from the configured anchor. You only need --start or --end when overriding the default sprint window.
Efficiency rules
- One command per task: use
overviewwhen the user asks for a schedule summary or total hours; only calllist-eventswhen full event details are needed. - Never run the same command twice: do not call
list-events --format jsonfollowed bylist-eventsin plain format; pick one. - Prefer configured sprint defaults: when
ICS_RANGE_START/ICS_RANGE_DAYSare set, use that active window without asking for a start date again. - Skip setup: do not call
check_dependencies.pybefore each command.
