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 is concise and specific about its capabilities—searching GIF providers, downloading, and extracting stills/sheets via CLI/TUI. However, it completely lacks a 'Use when...' clause, which is critical for Claude to know when to select this skill. Adding explicit trigger guidance and more natural user-facing keywords would significantly improve it.
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 GIFs.'
Include natural trigger terms users might say, such as 'animated images', '.gif', 'giphy', 'tenor', 'extract frames', 'sprite sheet', 'GIF thumbnail'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: search GIF providers, download results, and extract stills/sheets. Also mentions CLI/TUI as the interface, adding specificity. | 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. Per rubric guidelines, a missing 'Use when...' clause caps completeness at 2, and since the 'when' is entirely absent, this scores 1. | 1 / 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', 'giphy', 'tenor', or 'thumbnail extraction'. | 2 / 3 |
Distinctiveness Conflict Risk | The combination of GIF searching, downloading from providers via CLI/TUI, and extracting stills/sheets is a very specific niche that is unlikely to conflict with other skills. | 3 / 3 |

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, concise skill that provides highly actionable CLI examples organized into logical sections. Its main weakness is that the multi-step workflow (search → preview → download → extract) is mentioned but not explicitly sequenced with validation steps, which would help Claude chain operations reliably. Overall, it's an effective reference for using gifgrep.
Suggestions
Expand the 'Search → preview → download → extract' workflow into a numbered sequence with explicit validation (e.g., check download path exists before running `gifgrep still`), which would improve workflow clarity for chained operations.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient. Every line provides actionable CLI commands or essential configuration details. No unnecessary explanations of what GIFs are or how CLI tools work—it assumes Claude's competence throughout. | 3 / 3 |
Actionability | Nearly every section provides concrete, copy-paste-ready commands with specific flags and arguments. The quick start, download, stills/sheets, and output sections all give executable examples with real flag combinations. | 3 / 3 |
Workflow Clarity | The opening line mentions a 'Search → preview → download → extract' workflow, but the steps aren't sequenced with explicit validation checkpoints. The sections are organized by feature rather than as a clear multi-step process, and there's no error handling or verification guidance (e.g., checking if download succeeded before extracting stills). | 2 / 3 |
Progressive Disclosure | For a simple, single-file skill under 50 lines with no bundle files, the content is well-organized into clearly labeled sections that are easy to scan. Each section is focused and appropriately sized, making navigation straightforward. | 3 / 3 |
