rails-presenter
Creates presenter objects for view formatting using SimpleDelegator pattern with TDD. Use when extracting view logic from models, formatting data for display, creating badges/labels, or when user mentions presenters, view models, formatting, or display helpers.

Validation for skill structure
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 well-crafted skill description that excels across all dimensions. It provides specific concrete actions, includes natural trigger terms developers would use, explicitly states both what the skill does and when to use it, and carves out a distinct niche around the presenter pattern with SimpleDelegator.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Creates presenter objects', 'view formatting', 'SimpleDelegator pattern', 'TDD', 'extracting view logic from models', 'formatting data for display', 'creating badges/labels'. | 3 / 3 |
Completeness | Clearly answers both what ('Creates presenter objects for view formatting using SimpleDelegator pattern with TDD') and when ('Use when extracting view logic from models, formatting data for display, creating badges/labels, or when user mentions presenters, view models, formatting, or display helpers'). | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'presenters', 'view models', 'formatting', 'display helpers', 'badges/labels', 'view logic'. These cover common variations of how developers discuss this pattern. | 3 / 3 |
Distinctiveness Conflict Risk | Clear niche targeting the presenter/decorator pattern specifically with SimpleDelegator and TDD context. The combination of 'presenter', 'SimpleDelegator', and 'view formatting' creates a distinct trigger profile unlikely to conflict with general formatting or model skills. | 3 / 3 |

Implementation
77%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 skill with excellent TDD workflow clarity and fully executable code examples. The main weakness is moderate verbosity - the BasePresenter code (marked as 'already exists') and extensive common methods section could be externalized or trimmed. The skill effectively teaches the presenter pattern with proper validation checkpoints.
Suggestions
Remove or minimize the BasePresenter code block since it 'already exists' - a brief reference is sufficient
Move 'Common Presenter Methods' section to a separate PRESENTER_PATTERNS.md reference file to reduce main skill length
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient but includes some redundancy - the BasePresenter code block is shown even though it 'already exists', and the common presenter methods section duplicates patterns already demonstrated in the main example. Some tightening possible. | 2 / 3 |
Actionability | Excellent executable code throughout - complete RSpec examples, full presenter implementation, controller usage patterns, and copy-paste ready snippets. All code is concrete and runnable, not pseudocode. | 3 / 3 |
Workflow Clarity | Clear 4-step TDD workflow (RED-GREEN) with explicit validation checkpoints - 'Run spec to confirm RED', 'Run spec to confirm GREEN'. The checklist at the end provides additional verification. Sequence is unambiguous. | 3 / 3 |
Progressive Disclosure | Content is well-organized with clear sections, but the 'Common Presenter Methods' section adds significant length that could be in a separate reference file. The skill is somewhat monolithic at ~200 lines when it could reference external examples. | 2 / 3 |
