Discovery
67%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 is concise and specific about its capabilities, clearly identifying a niche around GIF searching, downloading, and frame extraction via CLI/TUI. Its main weaknesses are the lack of an explicit 'Use when...' clause and limited trigger term coverage for natural user language variations.
Suggestions
Add a 'Use when...' clause, e.g., 'Use when the user wants to search for GIFs, download animated images, extract frames or sprite sheets from GIF files.'
Include more natural trigger terms and variations such as 'animated images', '.gif', 'Giphy', 'Tenor', 'sprite sheet', 'frame extraction' to improve keyword coverage.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: search GIF providers, download results, extract stills/sheets. Also mentions CLI/TUI as the interface mechanism. | 3 / 3 |
Completeness | Clearly answers 'what does this do' (search, download, extract), but lacks an explicit 'Use when...' clause or trigger guidance for when Claude should select this skill. | 2 / 3 |
Trigger Term Quality | Includes relevant terms like 'GIF', 'CLI/TUI', 'download', 'stills', 'sheets', but misses common user variations like 'animated images', '.gif files', 'sprite sheet', 'frame extraction', or specific provider names (e.g., Giphy, Tenor). | 2 / 3 |
Distinctiveness Conflict Risk | The combination of GIF providers, CLI/TUI interface, downloading, and still/sheet extraction is a very specific niche unlikely to conflict with other skills. | 3 / 3 |
Total | 10 / 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 strong, concise skill that provides highly actionable CLI examples organized into clear sections. Its main weakness is that the multi-step workflow (search → preview → download → extract) is mentioned but not explicitly walked through as a sequenced process with intermediate checks. Overall it's an effective reference for using gifgrep.
Suggestions
Consider adding a brief end-to-end workflow example that chains the search → download → extract steps sequentially, showing how to verify each step's output before proceeding to the next.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Very lean and efficient. No unnecessary explanations of what GIFs are or how CLI tools work. Every line provides actionable information—commands, flags, or environment variables. The brief contextual notes (e.g., 'Kitty/Ghostty only') are essential constraints, not padding. | 3 / 3 |
Actionability | Nearly every section provides concrete, copy-paste-ready commands. The quick start section alone gives five executable examples covering different use cases. Flags, environment variables, and output formats are all specified concretely. | 3 / 3 |
Workflow Clarity | The opening line mentions a 'Search → preview → download → extract' workflow, but the steps aren't sequenced with explicit validation or checkpoints. The sections are organized by feature rather than as a guided workflow, so a user must mentally assemble the pipeline. For a non-destructive CLI tool this is acceptable but not exemplary. | 2 / 3 |
Progressive Disclosure | For a simple CLI tool skill under 50 lines, the content is well-organized into clearly labeled sections (Quick start, TUI, Download, Stills, Providers, Output, Environment). No external references are needed and the structure supports easy scanning and discovery. | 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.
