Discovery
89%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 solid skill description that clearly identifies its niche (Vitess/PlanetScale databases) and provides explicit trigger guidance. The main weakness is that the capability descriptions are somewhat categorical ('best practices', 'query optimization') rather than listing specific concrete actions. The trigger terms are well-chosen and domain-specific.
Suggestions
Replace general categories with specific concrete actions, e.g., 'Configure VSchema routing rules, optimize cross-shard queries, diagnose connection pool issues, set up keyspace sharding schemes'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Vitess/PlanetScale) and some actions ('best practices, query optimization, connection troubleshooting'), but these are somewhat general categories rather than multiple specific concrete actions like 'configure VSchema routing rules' or 'diagnose connection pool exhaustion'. | 2 / 3 |
Completeness | Clearly answers both what ('best practices, query optimization, connection troubleshooting for PlanetScale Vitess databases') and when ('Load when working with Vitess databases, sharding, VSchema configuration, keyspace management, or MySQL scaling issues') with explicit trigger guidance. | 3 / 3 |
Trigger Term Quality | Good coverage of natural terms users would say: 'Vitess databases', 'sharding', 'VSchema configuration', 'keyspace management', 'MySQL scaling issues', and 'PlanetScale'. These are terms users working with this technology would naturally use. | 3 / 3 |
Distinctiveness Conflict Risk | Very clear niche targeting Vitess/PlanetScale specifically. The combination of 'Vitess', 'VSchema', 'keyspace', and 'PlanetScale' creates distinct triggers unlikely to conflict with generic database or MySQL skills. | 3 / 3 |
Total | 11 / 12 Passed |
Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured reference skill that efficiently covers Vitess concepts, PlanetScale specifics, and SQL compatibility limitations. The progressive disclosure is excellent with clear navigation to detailed references. However, it lacks executable code examples and explicit workflow steps that would make it more immediately actionable for common tasks.
Suggestions
Add a 'Quick start' section with executable code showing connection setup and a basic query example
Include a concrete VSchema configuration example showing a simple sharded table setup
Add a workflow section for common operations like 'deploying schema changes' with explicit validation steps
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient, presenting information in tables and bullet points without explaining concepts Claude already knows. Every section adds value specific to Vitess/PlanetScale without padding. | 3 / 3 |
Actionability | While the content provides good conceptual guidance and lists limitations clearly, it lacks executable code examples for common operations like connecting, querying, or configuring VSchema. The guidance is informative but not copy-paste ready. | 2 / 3 |
Workflow Clarity | The skill mentions workflows like branching and deploy requests but doesn't provide explicit step sequences or validation checkpoints. For schema changes and migrations, there's no clear process with verification steps. | 2 / 3 |
Progressive Disclosure | Excellent structure with a clear overview and well-organized references table pointing to specific topics (VSchema, Schema Changes, VReplication, etc.). References are one level deep with clear descriptions of what each covers. | 3 / 3 |
Total | 10 / 12 Passed |
