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 term coverage and clear 'when to use' guidance. Its main weakness is that it describes topic coverage rather than concrete actions—it says what it knows about rather than what it does. Adding specific action verbs (e.g., 'Look up API details, provide usage examples, explain configuration') would strengthen the specificity dimension.
Suggestions
Add concrete action verbs describing what the skill does, e.g., 'Provides API references, code examples, and configuration guidance from official Rails documentation.'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description names the domain (Rails documentation) and lists many specific topic areas (ActiveRecord, routing, controllers, etc.), but it describes what it *covers* rather than what concrete actions it performs. It doesn't specify actions like 'look up API references', 'provide code examples', or 'explain configuration options'. | 2 / 3 |
Completeness | Clearly answers both 'what' (official Rails documentation) and 'when' with an explicit 'Use when asked about any Rails-specific topic' clause followed by a comprehensive list of trigger topics. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger terms users would say: 'Rails', 'ActiveRecord', 'routing', 'controllers', 'views', 'mailers', 'jobs', 'Action Cable', 'Action Text', 'Active Storage', 'migrations', 'validations', 'callbacks', 'associations', 'caching', 'security'. These are all terms Rails developers naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Clearly scoped to Rails-specific topics with 'Official Rails documentation' establishing a distinct niche. The extensive list of Rails-specific terms (ActiveRecord, Action Cable, Active Storage, etc.) makes it unlikely to conflict with general programming or other framework skills. | 3 / 3 |

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 reference index skill that serves as a topic map for Rails documentation. Its greatest strength is its organization — clean categorical grouping with clear one-line descriptions for each reference file. The main weakness is the lack of any inline actionable content (no quick-reference code snippets or common patterns), though this is somewhat mitigated by the skill's nature as a documentation index.
Suggestions
Consider adding a brief 'Quick Reference' section at the top with the 3-5 most commonly needed Rails patterns (e.g., common migration commands, route definitions, or validation syntax) to provide immediate actionable value before directing to reference files.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is purely a topic map with no unnecessary explanation. It doesn't explain what Rails is, what MVC means, or how ActiveRecord works — it trusts Claude already knows these concepts and just provides navigation to reference files. | 3 / 3 |
Actionability | The skill provides clear pointers to reference files with brief descriptions of what each covers, but contains no executable code, commands, or concrete examples itself. It's a directory/index rather than actionable guidance, though the descriptions are specific enough to guide file selection. | 2 / 3 |
Workflow Clarity | This is a reference/lookup skill rather than a multi-step workflow skill. The single task — finding the right Rails documentation for a given topic — is unambiguous with clear categorical organization. No destructive or batch operations are involved, so no validation checkpoints are needed. | 3 / 3 |
Progressive Disclosure | Excellent progressive disclosure structure: a concise overview/topic map at the top level with well-organized categories and one-level-deep references to specific guide files. Each reference has a brief description signaling its content, making navigation easy. | 3 / 3 |
