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—it is essentially a skill title and category label with a duplicated trigger term, providing almost no actionable information for Claude to determine when to select this skill. It lacks concrete capability descriptions, natural trigger terms users would say, and an explicit 'Use when...' clause.
Suggestions
Add specific concrete actions the skill performs, e.g., 'Generates Excel formulas including VLOOKUP, SUMIF, INDEX/MATCH, conditional formatting rules, and array formulas from natural language descriptions.'
Add an explicit 'Use when...' clause with natural trigger terms, e.g., 'Use when the user asks for help writing Excel formulas, spreadsheet calculations, cell references, or mentions .xlsx files and needs formula assistance.'
Remove the duplicated trigger term and expand with natural keyword variations users would actually say, such as 'spreadsheet formula', 'Excel function', 'calculate in Excel', 'lookup 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 barely answers 'what does this do' (generates Excel formulas, implied only from the title) and has no explicit 'when to use' clause. Both the what and when are very weak or missing. | 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 data skills, but the lack of concrete actions or file type triggers means it could still overlap with general Excel or 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 boilerplate meta-descriptions that repeat 'excel formula generator' without providing a single actual Excel formula, pattern, example, or actionable instruction. It fails on every dimension of the rubric.
Suggestions
Add concrete Excel formula examples with input/output demonstrations (e.g., VLOOKUP, INDEX/MATCH, SUMIFS patterns with sample data and expected results).
Replace the meta-description sections with actionable content: common formula patterns, syntax references, and copy-paste ready formulas for typical business automation scenarios.
Include a workflow for complex formula construction (e.g., 1. Identify lookup type → 2. Choose appropriate function → 3. Build formula → 4. Validate with test data).
Remove all self-referential 'this skill does X' language and replace with direct instructions that Claude can follow.
| 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 could do rather than actually doing anything actionable. | 1 / 3 |
Workflow Clarity | No workflow, steps, or process is defined. The skill claims to provide 'step-by-step guidance' but contains none. There are no validation checkpoints or sequences of any kind. | 1 / 3 |
Progressive Disclosure | The content is a flat, repetitive block with no meaningful structure. There are no references to detailed files, no examples to navigate to, and the sections are redundant rather than progressively disclosing useful information. | 1 / 3 |
Total | 4 / 12 Passed |
Validation
81%Checks the skill against the spec for correct structure and formatting. All validation checks must pass before discovery and implementation can be scored.
