Discovery
67%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 has a solid structure with an explicit 'Use when...' clause and identifies the Angular domain, but lacks concrete action verbs and specific enough trigger terms to clearly distinguish it from other UI-related skills. The capabilities listed are more like categories than specific actions, which reduces its effectiveness for skill selection among many options.
Suggestions
Add more specific concrete actions, e.g., 'Implements skeleton loaders, error boundary components, empty state placeholders, and async pipe patterns in Angular templates'.
Include more natural trigger terms users would say, such as 'spinner', 'loading indicator', 'error handling in Angular', 'Observable', 'RxJS', 'ngIf/ngSwitch', or '.component.ts'.
Strengthen distinctiveness by specifying Angular version context (e.g., 'Angular 14+') and mentioning Angular-specific patterns like 'signals', 'standalone components', or 'async pipe' to differentiate from React/Vue UI skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Angular UI) and mentions some areas (loading states, error handling, data display), but these are more categories than concrete actions. It doesn't list specific actions like 'create skeleton loaders', 'implement error boundaries', or 'build data tables'. | 2 / 3 |
Completeness | Clearly answers both 'what' (modern Angular UI patterns for loading states, error handling, and data display) and 'when' (Use when building UI components, handling async data, or managing component states) with an explicit 'Use when...' clause. | 3 / 3 |
Trigger Term Quality | Includes some relevant terms like 'Angular', 'UI components', 'loading states', 'async data', 'component states', but misses common variations users might say such as 'spinner', 'skeleton loader', 'error message', 'Observable', 'RxJS', 'ngIf', 'Angular template', or specific Angular version references. | 2 / 3 |
Distinctiveness Conflict Risk | While 'Angular' provides some specificity, terms like 'UI components', 'async data', and 'component states' are broad enough to overlap with other frontend framework skills (React, Vue) or general UI pattern skills. The description could conflict with a generic 'UI components' or 'frontend patterns' skill. | 2 / 3 |

Implementation
64%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a solid, highly actionable Angular UI patterns skill with excellent executable code examples and clear CORRECT/WRONG comparisons. Its main weaknesses are redundancy (same patterns repeated in anti-patterns section), monolithic structure that could benefit from splitting into referenced files, and lack of an explicit workflow sequence with validation checkpoints for building components end-to-end.
Suggestions
Remove the Anti-Patterns section and consolidate CORRECT/WRONG examples inline with each pattern section to eliminate redundancy and save ~40 lines.
Extract detailed patterns (forms, dialogs, error components) into separate referenced files and keep SKILL.md as a concise overview with links.
Remove the generic 'When to Use' and 'Limitations' boilerplate sections — they add no actionable information specific to this skill.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is fairly comprehensive but includes significant redundancy — the same patterns (loading states, error handling, button disabling) are shown multiple times in slightly different forms (main sections + anti-patterns section). Some content like the boilerplate 'When to Use' and 'Limitations' sections add no value. The decision tree and table are efficient, but overall the document could be tightened by ~30%. | 2 / 3 |
Actionability | Every pattern includes fully executable, copy-paste-ready Angular code with modern syntax (signals, @if/@for/@defer, standalone components). The examples are complete components with proper imports, dependency injection, and error handling — not pseudocode. The CORRECT/WRONG comparisons make guidance unambiguous. | 3 / 3 |
Workflow Clarity | The loading state decision tree provides a clear sequence for choosing UI states, and the checklist at the end is valuable. However, there are no explicit validation checkpoints or feedback loops for the overall component-building workflow — it's more a collection of patterns than a sequenced process. The checklist helps but lacks a 'verify' step. | 2 / 3 |
Progressive Disclosure | The content is well-structured with clear headers and sections, but it's a monolithic ~300-line document with no references to external files for detailed patterns. The form patterns, dialog patterns, and anti-patterns sections could be split into separate files. The 'Integration with Other Skills' section references other skills but doesn't link to them. | 2 / 3 |
