88%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A high-quality reference body: executable Swift for every core CloudKit surface, hard numeric limits, expert-level gotchas, and a workflow with genuine feedback loops and a safety rule against blind full resyncs. Its main costs are mild duplication between the error table, the error-handling switch, and the checklist, and a longer-than-necessary main body relative to its well-signposted reference file.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and expert-facing: tables, executable Swift, hard limits ('Max 1 MB per record (excluding CKAsset data)', 'Max 1024 keys, 1 MB total'), and gotchas, with almost no teaching of concepts Claude already knows. It falls short of anchor 5 because the CKError table and the handleCloudKitError switch restate the same strategies, and the Review Checklist duplicates earlier sections; better than anchor 3 because the padding is deliberate structure, not explanation. | 4 / 5 |
Actionability | Fully executable, copy-paste-ready Swift covering the common cases: CRUD, all three subscription types with notification handling, a complete CKSyncEngineDelegate, SwiftData ModelConfiguration, the NSUbiquitousKeyValueStore change-reason switch, account-status gating, and a concrete three-way merge. Placeholders like mergeValues/markSynced are inherently app-specific logic, which does not reduce executability of the covered cases. Matches anchor 5. | 5 / 5 |
Workflow Clarity | The Workflow section sequences setup verification, durable local change, token/state persistence, adversarial testing ('Test offline edits, partial failure, rate limiting, token expiry, conflict, account loss, zone deletion, and relaunch'), and error classification with a rerun-the-same-scenario feedback loop and an explicit guard ('Never restart a full sync blindly after partial success'), backed by a Review Checklist. Matches anchor 5's explicit validation and feedback loops. | 5 / 5 |
Progressive Disclosure | A real, one-level-deep bundle file (references/cloudkit-patterns.md) exists and is signposted twice with its contents enumerated (shares, assets, batch operations, Dashboard), and the TOC makes navigation easy. Falls short of anchor 5 because the ~480-line body inlines substantial detail (full conflict-merge code, the full KVO observer, error table plus switch) that could have been split into the reference; still well above anchor 3's 'buried references'. | 4 / 5 |
