Quality

Content

92%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is lean, fully executable, and clearly organized for applying the actor-persistence pattern; its only weak spot is progressive disclosure, since everything lives inline in one file with no reference split.

Suggestions

Split the detailed ViewModel integration and/or anti-patterns into a reference file (e.g., references/advanced-patterns.md) and link to it from the overview to improve progressive disclosure.

Merge the redundant 'When to Activate' and 'When to Use' sections into a single trigger section to tighten conciseness further.

Consider a brief validation note (e.g., confirming Codable round-trip or handling decode failures) for write-heavy usage, though current single-item atomic operations do not strictly require it.

DimensionReasoningScore

Conciseness

The body is lean and code-driven, assumes Claude's competence (no 'what is an actor' explanation), and every section earns its place; minor overlap between 'When to Activate' and 'When to Use' is not enough to drop below 3.

3 / 3

Actionability

Provides complete, executable Swift code for the actor repository, usage, and @Observable ViewModel integration that is copy-paste ready, not pseudocode.

3 / 3

Workflow Clarity

The pattern application is unambiguous and clearly sequenced (when to activate -> core pattern -> usage -> best practices -> anti-patterns), and single-item save/delete with .atomic writes are not destructive batch operations requiring validation feedback loops.

3 / 3

Progressive Disclosure

The skill is well-organized into sections but is a single monolithic file (~145 lines, over the 50-line simple-skill threshold) with no external references or detail/overview split, so it does not reach the one-level-deep reference structure of a 3.

Description

57%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is specific and distinctive about its Swift-actors persistence niche, but it omits an explicit 'Use when...' trigger clause, which caps both completeness and trigger_term_quality at 2.

Suggestions

Add an explicit 'Use when...' clause listing trigger situations (e.g., building offline-first apps, replacing DispatchQueue-based synchronization, needing thread-safe local storage).

Mention concrete repository operations (save, delete, find, loadAll) to lift specificity from architecture-description to listed actions.

Add common user-facing variations like 'Swift concurrency', 'local storage', or 'data races' to broaden natural keyword coverage.

DimensionReasoningScore

Specificity

Names the domain ('Thread-safe data persistence in Swift using actors') and concrete mechanism ('in-memory cache with file-backed storage'), but describes an architecture rather than listing multiple specific actions like save/find/delete, so it is not a 3.

2 / 3

Completeness

Clearly answers 'what' (actor-based persistence with cache + file backing) but provides no explicit 'when to use it' clause; per the guidelines a missing 'Use when...' caps completeness at 2.

2 / 3

Trigger Term Quality

Includes natural domain terms ('Swift', 'actors', 'thread-safe', 'data persistence', 'data races') a developer would say, but lacks common variations and has no 'Use when...' trigger phrasing, keeping it below 3.

2 / 3

Distinctiveness Conflict Risk

The combination 'Swift actors thread-safe persistence' is a clear niche with distinct triggers unlikely to conflict with other skills.
