92%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.
Excellent body content: a concise, well-sequenced overview with explicit verification steps, a review checklist, and a clean one-level-deep reference structure where every cited file exists and is signaled with when-to-read guidance. The only weakness is actionability — the body offers strong API-level decision rules but no executable examples, leaving minor gaps for tasks like setting up a @ModelActor or testing a migration.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and assumes Claude's competence — it names @ModelActor, PersistentIdentifier, FetchDescriptor, and autosave without explanation, and every line is a rule, decision, or pointer rather than padding. The Contents list is navigation structure, not over-explanation, so it does not warrant the minor-trimming penalty of a 4. | 5 / 5 |
Actionability | Guidance is concrete and API-specific ("Use `@Query` when a SwiftUI view owns a live query... Use `FetchDescriptor` for imperative, reusable, paginated, or actor-owned fetches"; "pass stable identifiers or `PersistentIdentifier` values across isolation boundaries rather than live model objects"), but the body contains no executable snippets (e.g., a minimal @ModelActor or migration setup) and verification advice like "test it with a copy of representative data" gives no method. Not 3: the decision rules name exact APIs and outcomes; not 5: guidance is decision-oriented rather than copy-paste ready, which is acceptable for an instruction-only skill but leaves minor gaps. | 4 / 5 |
Workflow Clarity | The five-step workflow is clearly sequenced with a conditional migration step ("If the schema changes, define a migration and test it with a copy of representative data"), explicit verification ("Build and verify create, fetch, update, delete, relaunch persistence, failure handling"), failure/rollback expectations in the migration section, and a 10-item review checklist. The destructive-operation cap does not apply because validation steps are explicitly present. | 5 / 5 |
Progressive Disclosure | The body is a lean overview and all seven referenced files (references/custom-stores-history-and-cloudkit.md, performance-predicates-and-modeling.md, containers-undo-previews-and-errors.md, indexing.md, swiftdata-queries.md, predicate-pitfalls.md, core-data-coexistence.md) exist in the bundle, are one level deep, and are clearly signaled with when-to-read guidance (e.g., "Read [Predicate Pitfalls](references/predicate-pitfalls.md) before debugging optional relationships, captured values, enums, or unsupported expressions") plus a consolidated References section. | 5 / 5 |
