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 severely lacking in all key areas. It reads like auto-generated boilerplate rather than a useful skill description, providing no information about what the skill actually does, what capabilities it offers, or when Claude should select it. The repeated trigger term and generic category label provide almost no value for skill selection.
Suggestions
Add specific actions the skill performs, e.g., 'Generates Chart.js configuration objects for bar charts, line graphs, pie charts, and scatter plots'
Add a 'Use when...' clause with natural trigger terms like 'Use when the user wants to create charts, visualize data, generate Chart.js configs, or mentions bar/line/pie charts'
Include common user phrases and file/format references like 'data visualization', 'graph', 'plot', 'chart configuration', 'JavaScript charts'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description only states 'Chart Js Config Creator' without describing any concrete actions. It doesn't explain what the skill actually does - no mention of creating configurations, generating charts, customizing visualizations, or any specific capabilities. | 1 / 3 |
Completeness | The description fails to answer 'what does this do' beyond the name, and provides no 'when should Claude use it' guidance. There is no 'Use when...' clause or equivalent explicit trigger guidance. | 1 / 3 |
Trigger Term Quality | The only trigger terms listed are 'chart js config creator' repeated twice, which is technical jargon. Missing natural user terms like 'chart', 'graph', 'visualization', 'Chart.js', 'data visualization', or 'plot data'. | 1 / 3 |
Distinctiveness Conflict Risk | The mention of 'Chart Js' provides some specificity to the Chart.js library, but 'Visual Content' category is generic. Could potentially conflict with other charting or visualization skills without clearer boundaries. | 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 that provides no actual value for Chart.js configuration creation. It contains only generic boilerplate text that could apply to any skill, with no Chart.js-specific code, configuration examples, or actionable guidance. The skill fails to teach Claude anything it doesn't already know.
Suggestions
Add concrete Chart.js configuration examples showing common chart types (bar, line, pie) with executable JavaScript/JSON code
Include a quick-start section with a minimal working Chart.js config that can be copy-pasted
Provide specific guidance on Chart.js options like scales, legends, tooltips, and responsive settings
Add validation steps or common pitfalls to avoid when creating Chart.js configurations
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is entirely boilerplate with no actual Chart.js-specific information. It explains what the skill does in abstract terms without providing any concrete configuration examples or code that Claude doesn't already know. | 1 / 3 |
Actionability | No executable code, no Chart.js configuration examples, no specific commands. The content only describes what the skill claims to do without providing any actual guidance on creating Chart.js configurations. | 1 / 3 |
Workflow Clarity | No workflow steps are provided. Claims to provide 'step-by-step guidance' but includes zero actual steps for creating Chart.js configurations. | 1 / 3 |
Progressive Disclosure | No structure beyond generic headings. No references to external files, no examples, no organized content hierarchy. The entire skill is a placeholder template with no real content to disclose. | 1 / 3 |
Total | 4 / 12 Passed |
