Discovery
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.
This is a strong, well-crafted skill description that clearly identifies its domain (Android Kotlin coroutines), lists specific capabilities, and includes an explicit 'Use when' clause with natural trigger terms. It uses proper third-person voice and covers both the 'what' and 'when' dimensions effectively. The description is concise yet comprehensive enough to distinguish it from other Android or Kotlin skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Write correct coroutine scopes, Flow collection, and dispatcher injection' — these are distinct, concrete technical capabilities in the Kotlin coroutines/Android domain. | 3 / 3 |
Completeness | Clearly answers both 'what' (write correct coroutine scopes, Flow collection, dispatcher injection in Android) and 'when' (explicit 'Use when' clause covering suspend functions, StateFlow vs SharedFlow choice, and injecting Dispatchers for testability). | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'suspend functions', 'StateFlow', 'SharedFlow', 'Dispatchers', 'coroutine scopes', 'Flow collection', 'testability'. These cover the main terms an Android developer would use when seeking help with coroutines. | 3 / 3 |
Distinctiveness Conflict Risk | Highly specific niche — Android Kotlin coroutines with explicit mention of StateFlow, SharedFlow, Dispatchers, and coroutine scopes. Unlikely to conflict with general Android skills or other coding skills due to the precise domain terminology. | 3 / 3 |

Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is concise and well-structured, effectively communicating Android concurrency rules without unnecessary explanation. Its main weakness is the lack of concrete, executable code examples — showing a DispatcherProvider implementation, a correct Flow collection pattern, or a viewModelScope usage example would significantly improve actionability. The anti-patterns section is a nice touch but would benefit from showing the correct alternative in code.
Suggestions
Add executable code examples for key patterns: DispatcherProvider interface/implementation, Flow collection with repeatOnLifecycle, and viewModelScope coroutine launch
Include a brief before/after code snippet in the Anti-Patterns section showing the wrong pattern vs. the correct one (e.g., GlobalScope vs. viewModelScope)
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Very lean and efficient. Every line conveys a specific rule or pattern without explaining what coroutines, Flow, or dispatchers are. Assumes Claude's competence with Android/Kotlin concepts. | 3 / 3 |
Actionability | Provides specific guidance (use viewModelScope, inject DispatcherProvider, use collectAsStateWithLifecycle) but lacks any executable code examples. No concrete code snippets showing DispatcherProvider injection, Flow collection patterns, or correct scope usage that would be copy-paste ready. | 2 / 3 |
Workflow Clarity | For a guidelines-style skill, the rules are clearly stated and organized into sections. However, there's no sequenced workflow for implementing these patterns (e.g., steps to set up DispatcherProvider, wire it through DI, and test). The skill describes what to do but not the order of operations. | 2 / 3 |
Progressive Disclosure | Clean overview structure with well-organized sections and a single-level reference to implementation details. Content is appropriately brief in the main file with a clear pointer to the reference file for the dispatcher pattern. | 3 / 3 |
