List Calendars

Critical Rules

• Read cross-cutting behaviors first: skills/shared/references/cross-cutting.md
• Read-only — never create, modify, or delete calendars

Context Files

Read these files before starting:

• skills/shared/references/cross-cutting.md — provider detection, error handling
• skills/shared/references/providers.md — CLI commands for listing calendars

Workflow

1. Detect Providers

Follow provider detection from cross-cutting.md. Stop if no provider is available.

2. List Calendars

Google Calendar:

gcalcli list

Microsoft 365:

TOKEN=$(az account get-access-token --resource https://graph.microsoft.com --query accessToken -o tsv)
curl -s -H "Authorization: Bearer $TOKEN" \
  "https://graph.microsoft.com/v1.0/me/calendars?\$select=name,color,isDefaultCalendar,canEdit"

3. Format Output

Present as a table grouped by provider:

## Calendars

### Google Calendar
| Calendar | Access |
|----------|--------|
| Personal | owner |
| Work | reader |
| Holidays in US | reader |

### Microsoft 365
| Calendar | Default | Color |
|----------|---------|-------|
| Calendar | Yes | Blue |
| Birthdays | No | Purple |

If only one provider is configured, omit the provider header grouping.
