Discovery
7%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This description is extremely thin—essentially just a skill name, a duplicated trigger phrase, and a category label. It lacks concrete capability descriptions, natural trigger terms users would actually say, and any explicit 'Use when...' guidance. It would perform very poorly in a multi-skill selection scenario.
Suggestions
Add specific concrete actions the skill performs, e.g., 'Generates Excel formulas including VLOOKUP, SUMIF, INDEX/MATCH, conditional formatting rules, and array formulas based on user requirements.'
Add an explicit 'Use when...' clause with natural trigger terms, e.g., 'Use when the user asks for help creating Excel formulas, spreadsheet calculations, cell references, lookup functions, or needs to build .xlsx formulas.'
Remove the duplicated trigger term and expand with varied natural keywords users would say, such as 'spreadsheet formula', 'Excel function', 'calculate cells', 'conditional formula', 'pivot table formula'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | The description only names the skill ('Excel Formula Generator') but does not describe any concrete actions like 'creates formulas', 'builds lookup functions', or 'generates VLOOKUP/SUMIF expressions'. It is essentially just a title repeated with category metadata. | 1 / 3 |
Completeness | The description fails to answer 'what does this do' beyond the title and completely lacks a 'Use when...' clause or any explicit trigger guidance explaining when Claude should select this skill. | 1 / 3 |
Trigger Term Quality | The only trigger terms listed are 'excel formula generator' repeated twice. It misses natural user phrases like 'spreadsheet formula', 'Excel function', 'VLOOKUP', 'SUMIF', 'calculate in Excel', '.xlsx', or 'spreadsheet calculation'. | 1 / 3 |
Distinctiveness Conflict Risk | The mention of 'Excel Formula' provides some specificity that distinguishes it from generic document or code skills, but the lack of concrete actions or file type triggers means it could still overlap with general Excel/spreadsheet skills. | 2 / 3 |

Implementation
0%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is an empty shell with no substantive content. It consists entirely of meta-descriptions and placeholder text that describe what an Excel formula generator skill would do without providing any actual formulas, examples, patterns, or actionable guidance. It fails on every dimension of the rubric.
Suggestions
Add concrete Excel formula examples organized by category (e.g., VLOOKUP/XLOOKUP, SUMIFS, INDEX/MATCH, dynamic arrays) with specific input/output demonstrations.
Include a workflow for formula generation: understand the data layout → identify the operation needed → select appropriate formula → validate with sample data → handle edge cases (blanks, errors).
Remove all meta-description sections ('When to Use', 'Example Triggers', 'Capabilities') that describe the skill abstractly and replace with actual formula patterns and best practices.
Add common formula patterns with copy-paste ready examples, such as error handling with IFERROR, conditional aggregation with SUMPRODUCT, and data validation formulas.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is entirely filler and meta-description. It explains what the skill does in abstract terms without providing any actual instructions, formulas, or useful content. Every section restates the same vague information. | 1 / 3 |
Actionability | There is zero concrete guidance—no Excel formulas, no code examples, no specific commands or patterns. The content only describes what it claims to do without actually doing it. | 1 / 3 |
Workflow Clarity | No workflow, steps, or process is defined. The skill mentions 'step-by-step guidance' and 'validates outputs' but provides neither steps nor validation procedures. | 1 / 3 |
Progressive Disclosure | The content is a flat, monolithic block of vague descriptions with no references to detailed materials, no structured sections with real content, and no navigation to supplementary resources. | 1 / 3 |
Total | 4 / 12 Passed |
Validation
