Booking Notifications (Dual-Channel)

Automated booking notifications via two channels:

Channel	Delivery	Format	Use Case
Telegram	Scheduled	HTML	Interactive commands, daily digest, search
Pushover	Real-time	Plain text	Emergency alerts with custom sound (dune)

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

Mandatory Preflight

Step 1: Check Sync Script Exists

ls -la "$HOME/.claude/plugins/marketplaces/cc-skills/plugins/calcom-commander/scripts/sync.ts" 2>/dev/null || echo "SCRIPT_NOT_FOUND"

Step 2: Verify Environment (Required)

echo "CALCOM_OP_UUID: ${CALCOM_OP_UUID:-NOT_SET}"
echo "TELEGRAM_BOT_TOKEN: ${TELEGRAM_BOT_TOKEN:+SET}"
echo "TELEGRAM_CHAT_ID: ${TELEGRAM_CHAT_ID:-NOT_SET}"
echo "HAIKU_MODEL: ${HAIKU_MODEL:-NOT_SET}"

All must be SET. If any are NOT_SET, run the setup command first.

Step 3: Verify Pushover (Optional)

echo "PUSHOVER_APP_TOKEN: ${PUSHOVER_APP_TOKEN:+SET}"
echo "PUSHOVER_USER_KEY: ${PUSHOVER_USER_KEY:+SET}"
echo "PUSHOVER_SOUND: ${PUSHOVER_SOUND:-dune}"
echo "WEBHOOK_RELAY_URL: ${WEBHOOK_RELAY_URL:-NOT_SET}"

If NOT_SET: Pushover is optional. Telegram-only operation still works. To enable, see pushover-setup.md.

Step 4: Verify Cal.com CLI Binary

ls -la "$HOME/.claude/plugins/marketplaces/cc-skills/plugins/calcom-commander/scripts/calcom-cli/calcom" 2>/dev/null || echo "BINARY_NOT_FOUND"

If BINARY_NOT_FOUND: Build it:

cd "$HOME/.claude/plugins/marketplaces/cc-skills/plugins/calcom-commander/scripts/calcom-cli" && bun install && bun run build

Notification Channels

Telegram (Scheduled Sync)

6h polling via launchd. Sends HTML-formatted messages for:

Category	Examples
NEW BOOKING	New interview scheduled, new consultation booked
CANCELLATION	Booking cancelled by attendee, host cancelled
UPCOMING	Booking starting in 1 hour, today's schedule
RESCHEDULED	Booking moved to new time, date changed

Pushover (Real-Time Webhook)

Instant notifications via Cloud Run webhook relay:

Event	Priority	Sound	Must Acknowledge?
New booking	2 (Emergency)	dune	Yes
Rescheduled	2 (Emergency)	dune	Yes
Cancelled	0 (Normal)	dune	No

Webhook Relay

The webhook relay is a lightweight Cloud Run service that bridges Cal.com webhooks to Pushover. See webhook-relay.md for deployment.

Running Manually

cd ~/own/amonic && bun run "$HOME/.claude/plugins/marketplaces/cc-skills/plugins/calcom-commander/scripts/sync.ts"

Sync Behavior

1. Fetches bookings from Cal.com API (last 6h window)
2. Compares against last-known state (file-based)
3. Detects new bookings, cancellations, and reschedules
4. Sends Telegram notification (HTML) for each change
5. Sends Pushover notification (plain text) if credentials configured
6. Updates state file for next sync cycle
7. Circuit breaker prevents cascade failures on API errors

mise Configuration (Agnostic Wiring)

Any repository can adopt these notifications by adding to

.mise.local.toml

:

[env]
# Required (Telegram)
CALCOM_OP_UUID = "<1password-uuid>"
TELEGRAM_BOT_TOKEN = "<bot-token>"
TELEGRAM_CHAT_ID = "<chat-id>"

# Optional (Pushover dual-channel)
PUSHOVER_APP_TOKEN = "<pushover-app-token>"
PUSHOVER_USER_KEY = "<pushover-user-key>"
PUSHOVER_SOUND = "dune"
WEBHOOK_RELAY_URL = "https://calcom-pushover-webhook-XXXXX.us-central1.run.app/"

Post-Change Checklist

• YAML frontmatter valid (no colons in description)
• Trigger keywords current
• Path patterns use $HOME not hardcoded paths
• Pushover graceful degradation verified (works without Pushover creds)

Post-Execution Reflection

After this skill completes, reflect before closing the task:

0. Locate yourself. — Find this SKILL.md's canonical path before editing.
1. What failed? — Fix the instruction that caused it.
2. What worked better than expected? — Promote to recommended practice.
3. What drifted? — Fix any script, reference, or dependency that no longer matches reality.
4. Log it. — Evolution-log entry with trigger, fix, and evidence.

Do NOT defer. The next invocation inherits whatever you leave behind.
