Discovery
89%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 skill description with excellent trigger terms and clear 'Use when' guidance that makes it easy for Claude to select appropriately. The main weakness is that it describes the integration components rather than listing specific concrete actions the skill enables. The technology-specific focus makes it highly distinctive and unlikely to conflict with other skills.
Suggestions
Add specific concrete actions like 'configure Auth0 tenant, implement biometric login flows, set up universal links/app links, handle authentication callbacks'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (React Native/Expo authentication) and mentions key components (biometric support, react-native-auth0 SDK, native deep linking), but doesn't list multiple concrete actions like 'configure login flows, implement biometric unlock, set up callback URLs'. | 2 / 3 |
Completeness | Explicitly answers both what (integrates react-native-auth0 SDK with native deep linking for biometric auth) and when ('Use when adding authentication to React Native or Expo mobile apps') with clear trigger guidance at the start. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'authentication', 'React Native', 'Expo', 'mobile apps', 'iOS/Android', 'biometric', 'Auth0', 'deep linking' - these are all terms developers naturally use when seeking this functionality. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with specific technology stack (React Native/Expo + Auth0 + biometric + deep linking) that clearly differentiates it from generic auth skills or web authentication skills. | 3 / 3 |
Total | 11 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is an exemplary skill file that demonstrates excellent token efficiency while providing comprehensive, actionable guidance. The workflow is clearly sequenced with platform-specific instructions, and the progressive disclosure pattern appropriately separates quick-start content from detailed references. The Common Mistakes table adds significant value for error prevention.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient, providing only necessary information without explaining concepts Claude already knows. Each section delivers actionable content without padding or unnecessary context about what Auth0 or React Native is. | 3 / 3 |
Actionability | Provides fully executable, copy-paste ready code examples for every step including installation commands, configuration files, and TypeScript components. The code is complete and specific, not pseudocode. | 3 / 3 |
Workflow Clarity | Clear 6-step numbered workflow with explicit sequencing. Each step builds on the previous one logically. The 'Common Mistakes' table serves as implicit validation checkpoints, and testing instructions are explicit in Step 6. | 3 / 3 |
Progressive Disclosure | Excellent structure with a concise quick start in the main file and clear one-level-deep references to detailed documentation (Setup Guide, Patterns Guide, API Reference). Navigation is well-signaled with descriptive links. | 3 / 3 |
Total | 12 / 12 Passed |
