Quality

Discovery

40%

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 identifies a clear technical niche with specific framework names (Avalonia, Zafiro, ReactiveUI), making it distinctive. However, it lacks explicit trigger guidance ('Use when...') and doesn't enumerate the specific actions or patterns it covers, limiting Claude's ability to know when to select it.

Suggestions

Add a 'Use when...' clause specifying triggers like 'when creating ViewModels in Avalonia', 'implementing multi-step wizards', or 'using ReactiveUI patterns'

List specific concrete actions such as 'create reactive ViewModels', 'implement wizard navigation flow', 'set up property bindings', 'configure reactive commands'

Include common term variations users might say: 'MVVM', 'reactive UI patterns', 'step-by-step wizard', 'Avalonia desktop app'

Dimension	Reasoning	Score
Specificity	Names the domain (Avalonia, Zafiro, ReactiveUI) and mentions 'ViewModel and Wizard creation patterns' as actions, but doesn't list specific concrete actions like 'create reactive commands', 'implement wizard navigation', or 'bind properties'.	2 / 3
Completeness	Describes what (ViewModel and Wizard patterns) but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill.	1 / 3
Trigger Term Quality	Includes relevant technical terms (ViewModel, Wizard, Avalonia, Zafiro, ReactiveUI) that users familiar with these frameworks would use, but missing common variations like 'MVVM', 'reactive programming', 'WPF-like', or 'cross-platform UI'.	2 / 3
Distinctiveness Conflict Risk	The combination of Avalonia + Zafiro + ReactiveUI is a very specific niche that is unlikely to conflict with other skills; these are distinct framework names that clearly identify when this skill applies.	3 / 3

Implementation

57%

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

This skill excels at organization and progressive disclosure, providing a clean overview that points to detailed guides. However, it critically lacks actionability - there are no code examples, concrete patterns, or executable guidance in the main skill file. The content reads more like a table of contents than a skill that teaches Claude how to perform tasks.

Suggestions

Add at least one concrete, executable code example showing a basic ViewModel pattern with ReactiveUI and Zafiro

Include a minimal working example of IEnhancedCommand usage that Claude can reference immediately

Add a quick-start code snippet for the most common use case (e.g., creating a simple ViewModel with a command)

Dimension	Reasoning	Score
Conciseness	The content is lean and efficient, listing core principles without over-explaining concepts Claude would already know. Every section serves a purpose with no padding or unnecessary context.	3 / 3
Actionability	The skill provides no concrete code examples, commands, or executable guidance. It only describes concepts and points to other files without showing any actual implementation patterns.	1 / 3
Workflow Clarity	Core principles are listed in a logical order suggesting a workflow, but there are no explicit steps, validation checkpoints, or sequences for implementing these patterns.	2 / 3
Progressive Disclosure	Excellent structure with a clear overview and well-signaled one-level-deep references to detailed guides. Navigation is easy with clearly labeled links to specific topics.	3 / 3
