Quality
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 that clearly identifies its niche (Auth0 SDK for Android authentication) and includes an explicit 'Use when' trigger clause. The trigger terms are excellent for developer-oriented queries. The main weakness is that the specific capabilities could be more granular—listing concrete actions like 'configure login screens, handle token refresh, implement biometric prompts' rather than feature categories.
Suggestions
Add more concrete action verbs describing specific tasks, e.g., 'configure login flows, implement biometric prompts, manage token storage, handle session refresh' to improve specificity.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Android authentication) and some actions (adding authentication, biometric-protected credentials, MFA), but doesn't list multiple concrete actions like 'configure login flows, store tokens, handle session refresh'. The capabilities are more like feature areas than specific actions. | 2 / 3 |
Completeness | Explicitly answers both what ('adding authentication to Android applications with Web Auth, biometric-protected credentials, and MFA, integrates com.auth0.android:auth0 SDK') and when ('Use when adding authentication to Android applications'). The 'Use when' clause is present and clear. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms: 'authentication', 'Android', 'Kotlin', 'Java', 'Web Auth', 'biometric', 'MFA', 'auth0', 'SDK', 'credentials'. These are terms a developer would naturally use when seeking help with Android authentication. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with a clear niche: Android-specific, Auth0 SDK-specific, with biometric and MFA focus. Very unlikely to conflict with generic auth skills, web auth skills, or iOS auth skills due to the specific platform and SDK references. | 3 / 3 |
Total | 11 / 12 Passed |
Implementation
85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured, highly actionable skill with excellent workflow clarity including validation checkpoints, error recovery loops, and user escalation paths. The progressive disclosure is strong with clear references to detailed documentation files. The main weakness is moderate verbosity in agent instruction blocks, which while useful, could be more concise given Claude's ability to infer behavioral patterns.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient with good use of tables and structured sections, but includes some verbose agent instructions and explanatory text that could be tightened. The build verification section with its extensive troubleshooting list and the detailed agent instruction blocks add significant length, though most content earns its place. | 2 / 3 |
Actionability | Provides fully executable Kotlin code for login/logout, specific gradle dependency lines, concrete build commands (`./gradlew assembleDebug`), and a version-fetching command (`gh api`). The code examples are copy-paste ready with proper imports and callback handling. | 3 / 3 |
Workflow Clarity | The 5-step workflow is clearly sequenced with explicit validation (build & verify step), error recovery loops with specific failure patterns and fixes, and a failcheck mechanism after 5-6 iterations. The credential confirmation gate at step 2 prevents proceeding without required configuration. | 3 / 3 |
Progressive Disclosure | Clean overview with well-signaled one-level-deep references to setup.md, integration.md, and api.md. The main file provides a quick start while detailed documentation is appropriately split into reference files with specific anchor links for common use cases. | 3 / 3 |
Total | 11 / 12 Passed |
