A read-only CLI and agent skill for querying the macOS Apple Calendar (EventKit SQLite) store via permissionless database snapshots without triggering TCC automation errors, with explicit UTC and local timestamps that guard against reference-date time conversion mistakes. Use it when an agent needs to inspect available calendars, search events by text, or retrieve date-bounded schedules on a local Mac without interactive permission prompts. Verified by 31 offline pytest cases in GitHub Actions CI and seven machine-checkable store invariants in `selftest`; requires macOS with an active Calendar store for live execution.
