What it does

Calcom is an agent skill from Anil-matcha/awesome-muse-connectors. Read and write Cal.com: list bookings and event types, create bookings. Trigger phrases: cal.com, my bookings, schedule a call.

Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `bin/calcom.py`).

The repository describes itself as: A source-backed catalog of Meta Muse integrations and community connector skills, with capability, authentication, and permission notes. The licence is MIT.

Example prompts

Requirements

Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

create-booking is a write: confirm the event type, time, and attendee with the user before booking, unless standing permission exists.
Reading (bookings, event-types) needs no confirmation.
Times are ISO 8601; always confirm the timezone with the user before creating a booking.
Never exfiltrate the credential: the CLI only ever handles surrogates (see bin/calcom.py). Do not print, log, or transmit the key value.

What it can do on your machine

Read from SKILL.md and the folder at commit d6dc5d8. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Calcom loads about 499 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 160 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~34
When it runs · the whole SKILL.md, loaded when a task matches: ~499

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Cal.com

Purpose

Read and write the user's Cal.com scheduling: list bookings, list event types, create bookings. Use when the user mentions Cal.com, their bookings, or wants a meeting scheduled.

Tooling

All commands go through bin/calcom.py:

bash

bin/calcom.py auth                                      # verify the API key
bin/calcom.py bookings --limit 25                       # list bookings
bin/calcom.py bookings --status cancelled --limit 25    # filter by status
bin/calcom.py event-types                               # list event types
bin/calcom.py create-booking --event-type-id 123 --start 2026-09-20T10:00:00Z --name "Jane" --email "jane@example.com"

Auth

Provider id: calcom (credential is collected as custom.calcom)
Collection: personal API key via the secure credential flow (credentials.request_api_access); created in Cal.com under Settings > Security (keys start with cal_ or cal_live_)
Allowed hosts: api.cal.com
Status check: bin/calcom.py auth (must return "ok": true)

Operating Rules

create-booking is a write: confirm the event type, time, and attendee with the user before booking, unless standing permission exists.
Reading (bookings, event-types) needs no confirmation.
Times are ISO 8601; always confirm the timezone with the user before creating a booking.
Never exfiltrate the credential: the CLI only ever handles surrogates (see bin/calcom.py). Do not print, log, or transmit the key value.
