28%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is essentially a hollow shell—it has a title and description suggesting comprehensive startup metrics guidance, but the body contains only generic, non-actionable boilerplate instructions with no domain-specific content. It delegates everything to a referenced resource file that doesn't exist in the bundle, making the skill nearly useless on its own.
Suggestions
Add concrete, domain-specific content: list the key metrics (MRR, CAC, LTV, churn, etc.) with formulas and calculation examples for different business models.
Include at least one executable example showing how to calculate a metric (e.g., a Python snippet computing MRR from subscription data or a table showing cohort retention).
Replace generic instructions ('Apply relevant best practices') with specific actionable steps like 'Calculate CAC by dividing total sales+marketing spend by new customers acquired in the period.'
Provide the referenced resources/implementation-playbook.md file or inline the essential content so the skill is functional standalone.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is relatively short but includes generic boilerplate ('Clarify goals, constraints, and required inputs', 'Apply relevant best practices') that adds no value. The 'Use this skill when' and 'Do not use this skill when' sections are tautological and waste tokens. | 3 / 5 |
Actionability | The skill provides no concrete guidance whatsoever—no formulas for metrics, no specific KPIs, no code, no examples. Instructions like 'Apply relevant best practices and validate outcomes' are entirely vague and non-executable. | 1 / 5 |
Workflow Clarity | There is a rough sequence implied (clarify goals → apply practices → verify), but steps are poorly defined with no specifics about what to validate or how. No checkpoints or concrete workflow for calculating or tracking metrics. | 2 / 5 |
Progressive Disclosure | References a resource file (resources/implementation-playbook.md) for detailed content, which is appropriate structure. However, no bundle files are provided to verify the reference exists, and the SKILL.md itself contains almost no substantive overview content to orient the reader before pointing elsewhere. | 3 / 5 |
