# Cronofy Management Skill

Manage and analyze Cronofy calendar API resources including calendars, events, and scheduling.

## API Conventions

### Authentication
All API calls use Bearer OAuth access token, injected automatically.

### Base URL
`https://api.cronofy.com/v1`

### Core Helper Function

```bash
#!/bin/bash

cronofy_api() {
    local method="$1"
    local endpoint="$2"
    local data="${3:-}"

    if [ -n "$data" ]; then
        curl -s -X "$method" \
            -H "Authorization: Bearer $CRONOFY_ACCESS_TOKEN" \
            -H "Content-Type: application/json" \
            "https://api.cronofy.com/v1${endpoint}" \
            -d "$data"
    else
        curl -s -X "$method" \
            -H "Authorization: Bearer $CRONOFY_ACCESS_TOKEN" \
            "https://api.cronofy.com/v1${endpoint}"
    fi
}
```

## Output Rules
- Target ≤50 lines per script output
- Use `jq` to extract only needed fields
- Never dump full API responses

## Phase 1: Discovery

```bash
#!/bin/bash
echo "=== Account Info ==="
cronofy_api GET "/account" \
    | jq '{account_id: .account.account_id, email: .account.email, scope: .account.scope}'

echo ""
echo "=== Calendars ==="
cronofy_api GET "/calendars" \
    | jq -r '.calendars[] | "\(.calendar_id[0:16])\t\(.calendar_name[0:30])\t\(.provider_name)\t\(.calendar_primary)\t\(.calendar_readonly)"' \
    | column -t | head -15

echo ""
echo "=== Upcoming Events ==="
cronofy_api GET "/events?from=$(date +%Y-%m-%d)&to=$(date -d '7 days' +%Y-%m-%d)&tzid=Etc/UTC" \
    | jq -r '.events[] | "\(.start.date // .start.time[0:16])\t\(.summary[0:30])\t\(.event_status)\t\(.attendees | length // 0) attendees"' \
    | head -15

echo ""
echo "=== Linked Profiles ==="
cronofy_api GET "/profiles" \
    | jq -r '.profiles[] | "\(.profile_id[0:16])\t\(.profile_name)\t\(.provider_name)\t\(.profile_connected)"' \
    | head -10
```

## Phase 2: Analysis

### Calendar Health

```bash
#!/bin/bash
echo "=== Event Summary (next 7 days) ==="
cronofy_api GET "/events?from=$(date +%Y-%m-%d)&to=$(date -d '7 days' +%Y-%m-%d)&tzid=Etc/UTC" \
    | jq '{
        total_events: (.events | length),
        by_status: (.events | group_by(.event_status) | map({(.[0].event_status): length}) | add),
        all_day: [.events[] | select(.start.date != null)] | length
    }'

echo ""
echo "=== Events Per Day ==="
cronofy_api GET "/events?from=$(date +%Y-%m-%d)&to=$(date -d '7 days' +%Y-%m-%d)&tzid=Etc/UTC" \
    | jq -r '.events[] | (.start.date // .start.time[0:10])' | sort | uniq -c | sort -k2

echo ""
echo "=== Free/Busy Overview ==="
cronofy_api POST "/free_busy" "{\"required_duration\": {\"minutes\": 30}, \"available_periods\": [{\"start\": \"$(date +%Y-%m-%dT%H:%M:%SZ)\", \"end\": \"$(date -d '1 day' +%Y-%m-%dT%H:%M:%SZ)\"}], \"participants\": [{\"members\": [{\"sub\": \"acc_id\"}], \"required\": \"all\"}]}" \
    | jq '{available_slots: (.available_periods | length)}' 2>/dev/null || echo "Free/busy: use availability endpoint for slot queries"
```

### Profile Sync Health

```bash
#!/bin/bash
echo "=== Profile Connection Status ==="
cronofy_api GET "/profiles" \
    | jq -r '.profiles[] | "\(.profile_name)\t\(.provider_name)\tconnected:\(.profile_connected)"' | head -10

echo ""
echo "=== Calendar Sync Summary ==="
cronofy_api GET "/calendars" \
    | jq '{
        total_calendars: (.calendars | length),
        by_provider: (.calendars | group_by(.provider_name) | map({(.[0].provider_name): length}) | add),
        primary: [.calendars[] | select(.calendar_primary == true)] | length,
        readonly: [.calendars[] | select(.calendar_readonly == true)] | length
    }'

echo ""
echo "=== Calendar Permissions ==="
cronofy_api GET "/calendars" \
    | jq -r '.calendars[] | "\(.calendar_name[0:25])\tprimary:\(.calendar_primary)\treadonly:\(.calendar_readonly)\tdeleted:\(.calendar_deleted)"' \
    | head -15
```

## Output Format

```
=== Account: <email> ===
Profiles: <n>  Calendars: <n>

--- Events (7d) ---
Total: <n>  Confirmed: <n>  Tentative: <n>
All-Day: <n>

--- Calendar Sync ---
By Provider: Google: <n>, Microsoft: <n>
Primary: <n>  Read-Only: <n>
```

## Anti-Hallucination Rules

1. **NEVER assume resource names** — always discover via CLI/API in Phase 1 before referencing in Phase 2.
2. **NEVER fabricate metric names or dimensions** — verify against the service documentation or `--help` output.
3. **NEVER mix CLI commands between service versions** — confirm which version/API you are targeting.
4. **ALWAYS use the discovery → verify → analyze chain** — every resource referenced must have been discovered first.
5. **ALWAYS handle empty results gracefully** — an empty response is valid data, not an error to retry.

## Counter-Rationalizations

| Shortcut | Counter | Why |
|----------|---------|-----|
| "I'll skip discovery and check known resources" | Always run Phase 1 discovery first | Resource names change, new resources appear — assumed names cause errors |
| "The user only asked for a quick check" | Follow the full discovery → analysis flow | Quick checks miss critical issues; structured analysis catches silent failures |
| "Default configuration is probably fine" | Audit configuration explicitly | Defaults often leave logging, security, and optimization features disabled |
| "Metrics aren't needed for this" | Always check relevant metrics when available | API/CLI responses show current state; metrics reveal trends and intermittent issues |
| "I don't have access to that" | Try the command and report the actual error | Assumed permission failures prevent useful investigation; actual errors are informative |

## Common Pitfalls
- **Date format**: Use `YYYY-MM-DD` for date-only events, ISO 8601 for timed events
- **Timezone**: Always specify `tzid` parameter for event queries
- **Event status**: `confirmed`, `tentative`, `cancelled`
- **Rate limits**: 30 requests/minute per access token
- **Pagination**: Events endpoint uses `pages.next_page` for cursor pagination
