Discovery
0%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 an unfilled template placeholder, not an actual skill description. It provides no information about what the skill does, when to use it, or any trigger terms. It scores the minimum on every dimension.
Suggestions
Replace the placeholder with an actual description that lists specific concrete actions the skill performs (e.g., 'Extracts text from images, resizes photos, converts between image formats').
Add an explicit 'Use when...' clause with natural trigger terms a user would say (e.g., 'Use when the user mentions images, photos, .png, .jpg, or image editing').
Ensure the description targets a clear, distinct domain so Claude can differentiate this skill from others in a large skill library.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | This is a template placeholder ('One sentence — what this skill does and when Claude should use it.') with no actual actions or capabilities described. It is entirely abstract meta-instruction. | 1 / 3 |
Completeness | Neither 'what' nor 'when' is answered. The text is a template prompt telling the author what to write, not an actual description. | 1 / 3 |
Trigger Term Quality | Contains zero natural keywords a user would say. The text is a placeholder instruction, not a real description, so there are no trigger terms whatsoever. | 1 / 3 |
Distinctiveness Conflict Risk | Completely generic placeholder text with no domain, no specificity, and no distinguishing characteristics. It would conflict with every other skill. | 1 / 3 |
Total | 4 / 12 Passed |
Implementation
0%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is an empty template/skeleton with no actual skill content — just placeholder headings and ellipses. It provides zero actionable guidance, no concrete examples, and no meaningful structure. It fails on every dimension because there is simply nothing substantive to evaluate.
Suggestions
Replace the placeholder '...' under Instructions with concrete, executable steps or code examples that teach Claude how to perform the specific task.
Add a clear description of what the skill does and when it should be used, replacing the generic 'Brief description' placeholder.
Include at least one concrete example with input and expected output to make the skill actionable.
If the skill involves multi-step processes, add numbered steps with explicit validation checkpoints.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is essentially a skeleton template with placeholder text ('Brief description...', '...') rather than actual skill content. While short, it contains no useful information — every token is wasted because none convey actionable guidance. | 1 / 3 |
Actionability | There are no concrete instructions, code examples, commands, or specific guidance of any kind. The 'Instructions' section is just an ellipsis placeholder with no actual content. | 1 / 3 |
Workflow Clarity | No workflow steps, sequences, or validation checkpoints are present. The content is entirely placeholder text with no discernible process. | 1 / 3 |
Progressive Disclosure | There is no meaningful content to organize, no references to external files, and no structure beyond a bare template skeleton. No bundle files are provided either. | 1 / 3 |
Total | 4 / 12 Passed |
