Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.01344 |
| Opus 5 | $0.00014 | $0.00672 |
| Sonnet 5 | $0.00005 | $0.00269 |
| Haiku 4.5 | $0.00003 | $0.00134 |
Grade A, and why
booking-notify scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Booking Notifications (Dual-Channel)
Automated booking notifications via two channels:
| Channel | Delivery | Format | Use Case |
|---|---|---|---|
| Telegram | Scheduled | HTML | Interactive commands, daily digest, search |
| Pushover | Real-time | Plain text | Emergency alerts with custom sound (dune) |
Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
Mandatory Preflight
Step 1: Check Sync Script Exists
ls -la "$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

What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

booking-notify is a skill published in the GitHub repository terrylica/cc-skills (72 stars, last pushed today), licensed MIT. It adds 27 tokens to every session and 1,344 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
