Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: api.cal.com.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

About this skill

What it does

This skill enables AI agents to interact directly with the Cal.com scheduling platform through its API. It allows agents to programmatically manage appointments, check availability, and integrate booking workflows into automated processes.

When to use it

  • Automating client onboarding by instantly creating calendar events for new sign-ups.
  • Building a chatbot that checks real-time slot availability before confirming meetings.
  • Syncing external CRM data with Cal.com calendars to prevent double-booking.
  • Triggering follow-up emails or tasks immediately after a scheduled call concludes.

Key capabilities

  • Direct API access to the Cal.com platform for scheduling operations.
  • Programmatic creation and management of calendar events.
  • Real-time availability checking within automated agent workflows.

Example prompts

  • "Create a new meeting slot for tomorrow at 2 PM with [email protected]."
  • "Check if I have any open slots this Friday between 10 AM and 12 PM."
  • "Cancel the appointment scheduled for next Tuesday and notify the user."

Tips & gotchas

Ensure your AI agent has valid authentication credentials before attempting to create or modify events. Always verify time zone settings in your Cal.com account to avoid scheduling conflicts across different regions.
