Calendar Agent Skill is an independent project. It is not affiliated with Apple,
Google, Proton, the IETF, or any calendar provider. Product names are used only to
describe interoperability.

The Python runtime installs separately licensed dependencies, including icalendar,
recurring-ical-events, python-dateutil, requests, defusedxml and keyring. Their
licenses and notices remain in their installed distributions. Dependency artifacts
are downloaded from PyPI, not bundled as project-owned code.
