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 clearly. However, it stays at a category level rather than listing concrete actions, and the trigger terms are somewhat generic for frontend development, which could cause overlap with other UI-related skills.
Suggestions
Add more specific concrete actions, e.g., 'Implements skeleton loaders, error boundaries, retry logic, and reactive data tables using Angular signals and RxJS Observables.'
Include more distinctive Angular-specific trigger terms like 'Observable', 'RxJS', 'ngIf/ngFor', 'Angular signals', 'Angular pipes', '.component.ts' to reduce conflict risk with other framework 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' (Angular UI patterns for loading states, error handling, 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 signals', or specific Angular version references. | 2 / 3 |
Distinctiveness Conflict Risk | While 'Angular' narrows the scope, terms like 'UI components', 'async data', and 'component states' are broad enough to overlap with other frontend framework skills or general UI pattern skills. It could conflict with React or Vue UI pattern skills if the trigger terms aren't specific enough. | 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, actionable Angular UI patterns reference with modern, executable code examples covering loading states, error handling, forms, and dialogs. Its main weaknesses are redundancy (the same anti-patterns are shown multiple times) and length — the content would benefit from splitting detailed component implementations into separate files and trimming repeated demonstrations. The checklist is a nice touch but the skill reads more as a pattern catalog than a guided workflow.
Suggestions
Remove the anti-patterns section or consolidate it with the inline CORRECT/WRONG examples already present in each section to eliminate redundancy.
Extract the full form component and dialog service into separate reference files (e.g., FORMS.md, DIALOGS.md) and link to them from the main skill to improve progressive disclosure.
Remove the generic 'When to Use' and 'Limitations' boilerplate sections — they add no actionable information beyond what the description already conveys.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is fairly well-structured but contains significant redundancy — the same patterns (loading states, error handling, button disabling) are demonstrated multiple times in slightly different forms, and the anti-patterns section largely repeats earlier examples. The boilerplate 'When to Use' and 'Limitations' sections add no value. At ~350 lines, this could be tightened considerably. | 2 / 3 |
Actionability | All guidance is backed by fully executable, copy-paste-ready Angular component code using modern patterns (signals, standalone components, new control flow syntax). Examples include complete component classes with dependency injection, template markup, and error handling — not pseudocode. | 3 / 3 |
Workflow Clarity | The loading state decision tree provides a clear sequence, and the checklist at the end is useful. However, there are no explicit validation checkpoints or feedback loops for the overall component-building workflow — it's more a catalog of patterns than a sequenced process. The checklist is good but lacks a 'verify' step. | 2 / 3 |
Progressive Disclosure | The content is well-sectioned with clear headers and a logical progression from loading → errors → buttons → forms → dialogs. However, at this length, several sections (e.g., the full form component, dialog service) would benefit from being split into separate reference files. The references to other skills at the bottom are minimal and lack links. No bundle files exist to offload detail. | 2 / 3 |
