Activation
0%This description is critically deficient across all dimensions. It provides no concrete actions, no natural trigger terms users would say, no guidance on when to use it, and is too generic to distinguish from other data-related skills. It reads as a placeholder rather than a functional skill description.
Suggestions
Add specific concrete actions the skill performs, e.g., 'Calculates sums, averages, counts, and groupings across datasets. Creates pivot-style summaries and rollups.'
Include a 'Use when...' clause with natural trigger terms like 'sum', 'total', 'average', 'group by', 'aggregate', 'summarize data', 'rollup'.
Specify the data types or contexts this applies to (e.g., 'tabular data', 'CSV files', 'database queries') to distinguish it from other analytics skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description contains no concrete actions whatsoever. 'Aggregation Helper' and 'Data Analytics' are abstract labels without any explanation of what the skill actually does (e.g., sum, average, group by, pivot). | 1 / 3 |
Completeness | The description fails to answer 'what does this do' (no actions described) and 'when should Claude use it' (no explicit use-case guidance beyond the unhelpful trigger phrase). | 1 / 3 |
Trigger Term Quality | The only trigger terms listed are 'aggregation helper' repeated twice, which is technical jargon users would not naturally say. Missing natural terms like 'sum', 'average', 'group by', 'totals', 'aggregate data'. | 1 / 3 |
Distinctiveness Conflict Risk | 'Data Analytics' is extremely broad and would conflict with many other analytics-related skills. Nothing distinguishes this from general data processing, statistics, or reporting skills. | 1 / 3 |

Implementation
0%This skill is an empty template with no actual content. It describes what an aggregation helper skill would theoretically do but provides zero actionable guidance, code examples, or concrete information about SQL aggregations, grouping, window functions, or any data analytics techniques. The entire content could be deleted without losing any useful information.
Suggestions
Add concrete SQL aggregation examples (GROUP BY, HAVING, window functions like SUM() OVER, COUNT(), AVG()) with executable code
Include specific patterns for common aggregation tasks: time-series rollups, hierarchical aggregations, running totals
Remove all generic boilerplate ('provides automated assistance', 'follows best practices') and replace with actual technical guidance
Add a quick reference section showing aggregation function syntax and common pitfalls (NULL handling, GROUP BY column requirements)
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is padded with generic boilerplate that provides no actual value. Phrases like 'provides automated assistance' and 'follows industry best practices' are vague filler that Claude doesn't need. | 1 / 3 |
Actionability | There is zero concrete guidance - no code, no commands, no specific examples of aggregation patterns. The content describes what the skill supposedly does but never shows how to actually perform any aggregation task. | 1 / 3 |
Workflow Clarity | No workflow is defined. The skill claims to provide 'step-by-step guidance' but contains no actual steps, sequences, or processes for performing aggregation tasks. | 1 / 3 |
Progressive Disclosure | The content is a shallow placeholder with no substantive information to organize. There are no references to detailed materials, examples, or related documentation that would help with actual aggregation tasks. | 1 / 3 |
