Creates XAML unit tests for GitHub issues in the Controls.Xaml.UnitTests project. Tests XAML parsing, compilation (XamlC), and source generation. Use when testing XAML-specific behavior, not UI interactions.

Quality

Content

100%

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

A tight, actionable skill body: concrete build/test commands, an explicit verification workflow, and clean one-level-deep reference to the conventions file. No verbosity or redundant concept explanations.

Dimension	Reasoning	Score
Conciseness	Lean body with no concept explanations Claude already knows (no 'what is XAML' preamble); every section (When to Use, Required Input, Workflow, Output) earns its place.	3 / 3
Actionability	Provides fully executable commands ('dotnet build ... -c Debug --no-restore -v q', 'dotnet test ... --filter ... --no-build') with specific paths and a copy-paste output template.	3 / 3
Workflow Clarity	Four clearly sequenced steps with explicit verification checkpoints (Step 3 'Verify Tests Compile and Run', Step 4 'Verify Test Behavior' with expected PASS/FAIL outcomes); the task is test creation, not destructive/batch work, so the feedback-loop cap does not apply.	3 / 3
Progressive Disclosure	No bundle files exist; the body is a well-organized overview that points one level deep to the authoritative conventions file (`.github/instructions/xaml-unittests.instructions.md`), clearly signaled in Step 1 and the References section.	3 / 3
	Total	12 / 12 Passed

Description

100%

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

A concise, well-targeted description that names concrete capabilities, supplies an explicit 'Use when' trigger, and cleanly distinguishes itself from UI-testing skills. No fluff, third-person voice, and within a reasonable length.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions ('Tests XAML parsing, compilation (XamlC), and source generation') rather than vague language, matching the score-3 anchor.	3 / 3
Completeness	Explicitly states both what it does ('Creates XAML unit tests... Tests XAML parsing, compilation (XamlC), and source generation') and when to use it via an explicit 'Use when testing XAML-specific behavior, not UI interactions' clause.	3 / 3
Trigger Term Quality	Covers natural domain terms a user would say ('XAML unit tests', 'XamlC', 'source generation', 'UI interactions') with good variation; not merely generic jargon.	3 / 3
Distinctiveness Conflict Risk	Clear niche (XAML unit tests in a specific project) with an explicit contrast against UI-interaction testing, making conflict with sibling skills unlikely.	3 / 3
	Total	12 / 12 Passed
