Activation

0%

This description is essentially a placeholder with no substantive content. It fails on all dimensions by only stating the skill name and category without describing capabilities, use cases, or meaningful trigger terms. The duplicate trigger term suggests this may be auto-generated boilerplate that was never properly filled in.

Suggestions

Add specific concrete actions the skill performs, e.g., 'Validates data schemas, detects null values, identifies outliers, checks referential integrity, and reports data anomalies in pipeline outputs.'

Add a 'Use when...' clause with natural trigger terms like 'validate data', 'check data quality', 'find data errors', 'data validation', 'null checks', 'data integrity', or 'anomaly detection'.

Specify the data formats or contexts this skill handles (e.g., 'CSV files', 'database tables', 'JSON payloads', 'ETL pipelines') to distinguish it from other data-related skills.

DimensionReasoningScore

Specificity

The description only names the skill ('Data Quality Checker') without describing any concrete actions. There are no specific capabilities listed like 'validates schemas', 'detects anomalies', or 'checks for null values'.

1 / 3

Completeness

The description fails to answer 'what does this do' beyond the name, and provides no explicit 'when to use' guidance. The 'Triggers on' section just repeats the skill name rather than describing actual use cases.

1 / 3

Trigger Term Quality

The trigger terms are just the skill name repeated twice ('data quality checker, data quality checker'). No natural user keywords like 'validate data', 'check for nulls', 'data validation', 'anomaly detection', or 'data integrity' are included.

1 / 3

Distinctiveness Conflict Risk

The description is extremely generic - 'Data Pipelines' and 'Data Quality Checker' could overlap with many data-related skills. No specific file types, data formats, or unique capabilities are mentioned to distinguish it.

Implementation

0%

This skill is an empty template with no substantive content. It describes capabilities in abstract marketing language but provides zero actionable guidance, code examples, or concrete instructions for data quality checking. The content would be useless to Claude attempting to perform actual data quality tasks.

Suggestions

Add concrete, executable code examples for common data quality checks (null detection, schema validation, duplicate detection, outlier identification)

Define a clear workflow with validation steps: e.g., 1) Profile data, 2) Define quality rules, 3) Run checks, 4) Review failures, 5) Remediate or flag

Include specific tool guidance (e.g., Great Expectations, dbt tests, custom Spark validations) with copy-paste ready configurations

Remove all generic filler text ('provides automated assistance', 'follows best practices') and replace with actual techniques and patterns

DimensionReasoningScore

Conciseness

The content is padded with generic filler text that explains nothing Claude doesn't already know. Phrases like 'provides automated assistance' and 'follows industry best practices' are meaningless without specifics.

1 / 3

Actionability

No concrete code, commands, or executable guidance provided. The entire skill describes what it does abstractly without showing how to actually perform data quality checks.

1 / 3

Workflow Clarity

No workflow steps, validation checkpoints, or process sequences are defined. The skill mentions 'step-by-step guidance' but provides none.

1 / 3

Progressive Disclosure

No references to detailed documentation, no structured navigation, and no separation of content. The skill is a shallow placeholder with no depth to disclose.
