What this skill does
Cal.com — Printing Press CLI Prerequisites: Install the CLI This skill drives the cal-com-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: cal-com-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer): If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. When to Use This CLI Reach for cal-com-pp-cli whenever an agent needs to read or mutate a Cal.com calendar without burning context on the multi-call dance the API requires for booking and rescheduling. The local store makes 'what's on my calendar', 'when am I free', 'who is overloaded', and 'where are my conflicts' near-instant offline answers. The composed book and reschedule next commands are the right tools for transactional bookings; the endpoint-mirror coverage is there for everything else. Unique Capabilities These capabilities aren't available in any other tool for this API. Composed booking flows book — Schedule an attendee onto one of your event types in a single composed call — slot check, optional reservation, create, optional confirm. For the host scripting an attendee onto their calendar (admin onboarding, recruiter pre-fill, test fixtures). For the normal flow where the attendee picks their own time, share a URL from link list instead. slots find — Find first available slots across multiple event-type IDs in one call, ranked by start time. Use this when you don't know which event type fits — let the caller pick from a ranked merged list. …
