Discovery
7%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 description is extremely thin—essentially just a title and category label with no substantive content. It lacks concrete actions, natural trigger terms, and any explicit guidance on when to use the skill. It would be nearly indistinguishable from other visual/charting skills in a large skill library.
Suggestions
Add specific concrete actions such as 'Generates Chart.js configuration objects for bar, line, pie, doughnut, and scatter charts with customizable options, colors, and datasets.'
Include an explicit 'Use when...' clause, e.g., 'Use when the user asks to create a chart, graph, or data visualization using Chart.js, or needs a Chart.js config object.'
Add natural trigger terms users would say: 'chart', 'graph', 'Chart.js', 'data visualization', 'bar chart', 'line chart', 'pie chart', '.js chart config'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description only names the tool ('Chart Js Config Creator') and a vague category ('Visual Content') but lists no concrete actions like 'generate Chart.js configuration objects', 'create bar/line/pie charts', or 'customize chart options'. | 1 / 3 |
Completeness | The description fails to clearly answer 'what does this do' beyond the name itself, and there is no explicit 'Use when...' clause or equivalent guidance on when Claude should select this skill. | 1 / 3 |
Trigger Term Quality | The only trigger terms listed are the redundant 'chart js config creator' repeated twice. It misses natural user phrases like 'chart', 'graph', 'Chart.js', 'visualization', 'bar chart', 'line chart', 'data visualization', etc. | 1 / 3 |
Distinctiveness Conflict Risk | The mention of 'Chart Js Config' does narrow the domain somewhat to Chart.js specifically, which distinguishes it from generic charting or visualization skills, but the lack of detail about specific capabilities and the vague 'Visual Content' category still leave room for overlap. | 2 / 3 |

Implementation
0%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is an empty template with no actual content about Chart.js configuration creation. It consists entirely of generic boilerplate that repeats the skill name without providing any actionable guidance, code examples, configuration patterns, or Chart.js-specific knowledge. It adds zero value beyond what Claude already knows.
Suggestions
Add concrete, executable Chart.js configuration examples (e.g., a complete config object for a bar chart, line chart, pie chart) that Claude can use as templates.
Include specific guidance on Chart.js options, data structure, and common customization patterns (colors, axes, legends, responsive settings) instead of abstract capability descriptions.
Define a clear workflow: e.g., 1) Determine chart type from user request, 2) Build data structure, 3) Configure options, 4) Output complete config object—with validation of the output format.
Remove all meta-description sections ('When to Use', 'Example Triggers', 'Capabilities') that describe the skill rather than teaching Chart.js configuration creation.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is entirely filler and boilerplate. It explains nothing Claude doesn't already know, repeats the phrase 'chart js config creator' excessively, and provides zero actual technical content about creating Chart.js configurations. | 1 / 3 |
Actionability | There is no concrete guidance whatsoever—no code examples, no Chart.js configuration snippets, no specific commands or patterns. The content only describes what the skill would do in abstract terms without actually doing it. | 1 / 3 |
Workflow Clarity | No workflow, steps, or process is defined. The skill claims to provide 'step-by-step guidance' but contains none. There are no validation checkpoints or any sequenced instructions. | 1 / 3 |
Progressive Disclosure | The content is a flat, uninformative page with no meaningful structure. Sections exist but contain no substantive content—they are just meta-descriptions of what the skill supposedly does. No references to detailed resources or examples. | 1 / 3 |
