Standardize and validate SKILL.md files against the Agent Skills specification (agentskills.io). Use when creating new skills, auditing existing skills for spec compliance, converting legacy skill formats to standard structure, or improving descriptions for reliable triggering. Triggers on: "validate skill", "create SKILL.md", "standardize skill format", "check skill spec", "skill frontmatter", "improve skill description", "add evals to skill".

Discovery
100%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 is a well-crafted skill description that excels across all dimensions. It provides specific capabilities, comprehensive trigger terms that match natural user language, explicit guidance on when to use it, and a clear niche that distinguishes it from other skills. The description follows best practices by using third person voice and including both a 'Use when' clause and explicit trigger terms.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple concrete actions: 'Standardize and validate SKILL.md files', 'creating new skills', 'auditing existing skills', 'converting legacy skill formats', 'improving descriptions'. These are specific, actionable capabilities. | 3 / 3 |
Completeness | Clearly answers both what (standardize and validate SKILL.md files against spec) and when (explicit 'Use when...' clause with multiple scenarios plus explicit 'Triggers on:' section with specific phrases). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger terms users would say: 'validate skill', 'create SKILL.md', 'standardize skill format', 'check skill spec', 'skill frontmatter', 'improve skill description', 'add evals to skill'. These match realistic user requests. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with clear niche around SKILL.md files and the Agent Skills specification. The specific file format (.md), spec reference (agentskills.io), and specialized trigger terms make conflicts with other skills unlikely. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is an exemplary skill file that demonstrates best practices for skill documentation. It efficiently covers the Agent Skills specification with actionable templates, concrete examples, and clear validation workflows. The use of tables for structured data and the before/after examples for descriptions are particularly effective.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is lean and efficient, using tables for structured data, avoiding explanations of concepts Claude already knows, and every section serves a clear purpose. No padding or unnecessary context. | 3 / 3 |
Actionability | Provides fully executable bash commands, complete YAML templates, concrete before/after examples, and copy-paste ready code blocks. The validation script usage and JSON schema for evals are specific and actionable. | 3 / 3 |
Workflow Clarity | Clear 5-step numbered workflow with explicit validation as Step 1. The validation script output example shows exactly what feedback to expect, and the process flows logically from validate → write description → create → convert → add evals. | 3 / 3 |
Progressive Disclosure | Well-organized with clear sections, tables for reference data, and external links to detailed documentation. Content is appropriately split between quick-reference tables and detailed instructions without nesting references. | 3 / 3 |
Total | 12 / 12 Passed |
Validation
