Conciseness

The body is code-first and dense with no conceptual padding, but the opening line "Use EventKit for calendar and reminder authorization, CRUD, recurrence, alarms, and system editors" duplicates the frontmatter description, and the Contents TOC adds trimmable overhead — minor instances that could be trimmed, fitting anchor 4 rather than the every-token-earns-its-place anchor 5.

Actionability

Five executable Swift snippets (requestFullAccessToEvents, allowsContentModifications guard, explicit TimeZone, batched commit, single-store usage) in copy-paste-ready WRONG/CORRECT form cover the common failure cases, matching the anchor-5 fully-executable example.

Workflow Clarity

The 5-step Workflow ends with an explicit verification step ("Observe store changes and verify denied/restricted access, recurrence edits, timezone changes, and external modifications"), a Review Checklist provides checkpoints, and the batch-save checklist item specifies a full error-recovery feedback loop (reset(), discard invalidated EKObjects, refetch, retry) — satisfying the anchor-5 criteria including the batch-operation feedback-loop requirement.

Progressive Disclosure

The body is a lean overview with details split into two real, verified, one-level-deep reference files (references/core-implementation.md, references/eventkit-patterns.md), each linked with topic-scoped routing ("Read [core implementation details] for authorization, events, reminders…"), matching the anchor-5 clear-overview pattern; the sibling cross-link between the two references does not bury content two levels deep.

Specificity

"Creates, reads, edits, and presents calendar events or reminders" lists multiple concrete actions with comprehensive coverage, matching the anchor-5 pattern; deletion and other operations are additionally covered via "event/reminder CRUD" in the trigger clause, so the anchor-4 minor-gaps example is a worse fit.

Completeness

It clearly answers "what" ("Creates, reads, edits, and presents calendar events or reminders with EventKit and EventKitUI") and "when" ("Use for authorization, event/reminder CRUD, calendars, recurrence, alarms, change observation, event editors, viewers, calendar choosers, or SwiftUI wrappers") with concrete trigger phrases, exactly matching the anchor-5 example structure.

Trigger Term Quality

The "Use for" clause covers many natural terms (calendars, recurrence, alarms, reminders, event editors, SwiftUI wrappers) but misses common user phrasings like "schedule", "appointments", or platform keywords (iOS/macOS), fitting anchor 4 rather than the comprehensive anchor 5.

Distinctiveness Conflict Risk

The EventKit/EventKitUI calendar-and-reminders niche with framework-specific triggers (recurrence rules, calendar choosers, change observation) is clearly distinct with minimal conflict risk against other skills.
