Activation
7%This description is essentially a placeholder that provides almost no useful information for skill selection. It repeats the skill name as trigger terms, lacks any concrete capability descriptions, and provides no guidance on when to use it. The only slightly redeeming quality is that 'cohort analysis' is a somewhat specific domain term.
Suggestions
Add specific actions the skill performs, e.g., 'Segments users into time-based cohorts, calculates retention rates, and visualizes cohort behavior over time'
Include a 'Use when...' clause with natural trigger terms like 'retention analysis', 'user cohorts', 'customer lifetime analysis', 'churn by signup date'
Add file type or data format triggers such as 'user event data', 'signup timestamps', 'transaction history'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description only names the skill ('Cohort Analysis Creator') without describing any concrete actions. There are no specific capabilities listed like 'segments users by signup date', 'calculates retention rates', or 'generates cohort tables'. | 1 / 3 |
Completeness | The description fails to answer 'what does this do' beyond the name, and provides no 'when should Claude use it' guidance. The 'Triggers on' section just repeats the skill name rather than providing meaningful trigger scenarios. | 1 / 3 |
Trigger Term Quality | The trigger terms are just the skill name repeated twice ('cohort analysis creator, cohort analysis creator'). Missing natural user phrases like 'retention analysis', 'user cohorts', 'customer segments', 'churn analysis', or 'time-based grouping'. | 1 / 3 |
Distinctiveness Conflict Risk | While 'cohort analysis' is a specific analytical technique, the lack of detail about what distinguishes this from general data analytics skills creates moderate overlap risk. The category mention 'Data Analytics' is too broad to differentiate. | 2 / 3 |

Implementation
0%This skill is an empty template with no substantive content. It describes capabilities in abstract terms but provides zero actionable guidance on how to actually create cohort analyses—no SQL examples, no visualization patterns, no methodology for defining cohorts or measuring retention/behavior over time.
Suggestions
Add concrete SQL examples showing how to define cohorts (e.g., by signup date, first purchase) and track metrics over time periods
Include a clear workflow: 1) Define cohort criteria, 2) Write cohort assignment query, 3) Calculate metrics per cohort/period, 4) Visualize results
Provide a complete, executable example with sample output showing a cohort retention table or chart
Remove all generic boilerplate ('Provides step-by-step guidance', 'Follows industry best practices') and replace with actual guidance
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is padded with generic boilerplate that explains nothing Claude doesn't already know. Phrases like 'provides automated assistance' and 'follows industry best practices' are meaningless filler with no actionable information. | 1 / 3 |
Actionability | No concrete code, SQL queries, examples, or specific instructions are provided. The skill describes what it does abstractly ('Generates production-ready code') but never shows how to actually create a cohort analysis. | 1 / 3 |
Workflow Clarity | No workflow is defined. Despite claiming to provide 'step-by-step guidance,' there are no actual steps, no sequence, and no validation checkpoints for creating cohort analyses. | 1 / 3 |
Progressive Disclosure | The content is a flat, uninformative structure with no references to detailed materials, examples, or supporting documentation. The 'Related Skills' section mentions a category but provides no navigation. | 1 / 3 |
