Validation for skill structure
Activation
0%This description is severely underdeveloped and essentially just restates the skill name without providing any useful information. It lacks concrete actions, natural trigger terms, explicit usage guidance, and distinctive characteristics that would help Claude select it appropriately from a skill library.
Suggestions
Add specific concrete actions the skill performs, e.g., 'Constructs multi-table SQL joins, optimizes join performance, handles LEFT/RIGHT/INNER/OUTER joins, resolves ambiguous column references'
Include a 'Use when...' clause with natural trigger terms users would say, e.g., 'Use when the user mentions joining tables, combining datasets, SQL joins, merge queries, or multi-table queries'
Remove the redundant duplicate trigger term and replace with varied natural language terms like 'join tables', 'combine data', 'SQL merge', 'relational queries'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description uses vague language like 'Complex Join Helper' without explaining what concrete actions it performs. No specific capabilities are listed - it doesn't explain what kind of joins, what data sources, or what outputs. | 1 / 3 |
Completeness | The description fails to answer 'what does this do' beyond the name, and has no 'Use when...' clause or equivalent guidance for when Claude should select this skill. Both what and when are very weak. | 1 / 3 |
Trigger Term Quality | The only trigger terms listed are 'complex join helper' repeated twice, which is technical jargon users wouldn't naturally say. Missing natural terms like 'SQL joins', 'merge tables', 'combine datasets', 'LEFT JOIN', 'multiple tables'. | 1 / 3 |
Distinctiveness Conflict Risk | The description is extremely generic - 'Data Analytics' could overlap with countless other skills. Without specific triggers or capabilities, it would conflict with any data-related skill. | 1 / 3 |

Implementation
0%This skill is an empty template with no actual content about complex SQL joins. It contains only meta-descriptions of what a skill should do without any concrete guidance, code examples, join patterns, or actionable instructions. The skill provides zero value as it teaches Claude nothing about complex joins.
Suggestions
Add concrete SQL examples showing complex join patterns (self-joins, multi-table joins, joins with subqueries, window functions with joins)
Include specific guidance on join optimization, index usage, and common pitfalls with complex joins
Provide a workflow for analyzing and constructing complex joins: understand data relationships → identify join keys → write and validate join → optimize performance
Remove all boilerplate meta-content ('This skill provides...', 'When to Use...') and replace with actual technical content
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is entirely boilerplate with no actual technical substance. It explains what the skill does in abstract terms without providing any concrete information Claude doesn't already know. | 1 / 3 |
Actionability | No concrete code, commands, SQL examples, or specific guidance for complex joins. The content describes rather than instructs, with vague promises like 'provides step-by-step guidance' without actually providing any. | 1 / 3 |
Workflow Clarity | No workflow is defined. There are no steps, no sequence, no validation checkpoints. The skill claims to provide 'step-by-step guidance' but contains zero actual steps. | 1 / 3 |
Progressive Disclosure | No structure beyond generic headings. No references to detailed materials, no examples, no links to related documentation. The content is a shallow placeholder with no depth to disclose. | 1 / 3 |
