Validation for skill structure
Discovery
50%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
The description effectively communicates specific capabilities for GIF-related operations and occupies a clear niche. However, it critically lacks explicit trigger guidance ('Use when...') which would help Claude know when to select this skill, and could benefit from more natural user-facing keywords.
Suggestions
Add a 'Use when...' clause with trigger scenarios like 'Use when the user wants to search for GIFs, download animated images, or extract frames from GIF files'
Include common trigger terms users might say: 'animated images', 'giphy', 'tenor', '.gif files', 'GIF frames', 'convert GIF to image'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'Search GIF providers', 'download results', 'extract stills/sheets'. These are clear, actionable capabilities. | 3 / 3 |
Completeness | Describes what the skill does but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. | 1 / 3 |
Trigger Term Quality | Includes relevant terms like 'GIF', 'CLI/TUI', 'download', 'stills/sheets', but missing common variations users might say like 'animated images', 'giphy', 'tenor', or file extensions like '.gif'. | 2 / 3 |
Distinctiveness Conflict Risk | Very specific niche combining GIF searching, downloading, and frame extraction via CLI/TUI. Unlikely to conflict with other skills due to the unique combination of GIF-specific operations. | 3 / 3 |
Total | 9 / 12 Passed |
Implementation
87%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-crafted skill that efficiently documents a CLI tool. It excels at conciseness and actionability with concrete, executable examples throughout. The workflow could be slightly more explicit about how the pieces connect, but for a straightforward CLI tool, the organization is effective.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. No unnecessary explanations of what GIFs are or how CLI tools work. Every line provides actionable information with minimal prose. | 3 / 3 |
Actionability | Provides concrete, copy-paste ready commands throughout. Examples cover the full workflow from search to download to extraction with specific flags and options. | 3 / 3 |
Workflow Clarity | The workflow is implied (Search → preview → download → extract) but not explicitly sequenced with steps. For a CLI tool this is acceptable, but the relationship between commands could be clearer for multi-step operations. | 2 / 3 |
Progressive Disclosure | Well-organized sections that logically group related functionality. For a simple CLI tool skill under 50 lines, the structure is appropriate with clear headers and no need for external file references. | 3 / 3 |
Total | 11 / 12 Passed |
Validation
72%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
