Activation
7%This description is severely underdeveloped, essentially just restating the skill name without explaining capabilities or providing meaningful trigger guidance. It lacks concrete actions, natural user language, and explicit usage scenarios. The duplicate trigger term suggests auto-generated content without human refinement.
Suggestions
Add specific actions the calculator performs, e.g., 'Calculates p-values, confidence intervals, and effect sizes for A/B tests and hypothesis testing'
Include a 'Use when...' clause with natural trigger terms like 'A/B test results', 'is this statistically significant', 'p-value', 'sample size calculation', 'hypothesis test'
Remove the redundant trigger term and replace with diverse variations users would naturally say when needing statistical analysis
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description only names the tool ('Statistical Significance Calculator') without describing any concrete actions. It doesn't explain what calculations it performs, what inputs it takes, or what outputs it produces. | 1 / 3 |
Completeness | The description fails to answer 'what does this do' beyond the name, and the 'when' guidance is just a duplicate trigger phrase. There's no explicit 'Use when...' clause explaining scenarios for activation. | 1 / 3 |
Trigger Term Quality | The trigger terms are redundant (same phrase listed twice) and overly specific. Missing natural variations users would say like 'p-value', 'A/B test', 'significance test', 'is this result significant', or 'hypothesis testing'. | 1 / 3 |
Distinctiveness Conflict Risk | The specific mention of 'statistical significance' provides some distinctiveness from general data analytics skills, but the vague 'Data Analytics skill category' framing could cause overlap with other analytics tools. | 2 / 3 |

Implementation
0%This skill content is an empty template that provides no actual value. It contains only meta-descriptions of what a skill should do without any concrete guidance on statistical significance testing - no formulas, no code examples, no explanation of t-tests, chi-square tests, p-values, or confidence intervals. The content is entirely unusable for its stated purpose.
Suggestions
Add concrete code examples for common statistical tests (t-test, chi-square, ANOVA) with executable Python/SQL snippets using libraries like scipy.stats
Include the actual formulas and interpretation guidelines for p-values, confidence intervals, and effect sizes
Provide a clear workflow: 1) Define null/alternative hypotheses, 2) Select appropriate test, 3) Calculate test statistic, 4) Interpret results with specific thresholds
Add practical examples with sample data showing input/output for A/B testing scenarios common in business analytics
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is entirely boilerplate with no actual substance. It repeats 'statistical significance calculator' multiple times without providing any real information, and explains generic concepts Claude already knows (like 'provides step-by-step guidance'). | 1 / 3 |
Actionability | There is zero concrete guidance - no formulas, no code, no specific methods for calculating statistical significance. The content only describes what the skill claims to do without actually doing it. | 1 / 3 |
Workflow Clarity | No workflow is provided whatsoever. A statistical significance calculator should include steps like defining hypotheses, selecting test type, calculating test statistics, and interpreting p-values - none of which are present. | 1 / 3 |
Progressive Disclosure | The content is a flat, repetitive structure with no meaningful organization. There are no references to detailed materials, examples, or related documentation that would help with actual statistical calculations. | 1 / 3 |
