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 clearly defines its scope for real-time communication systems. It provides explicit trigger conditions, lists concrete capabilities, and uses domain-specific terminology that users would naturally employ. The description effectively distinguishes itself from general web development or API skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'bidirectional messaging, horizontal scaling with Redis, presence tracking, room management' - these are clear, actionable capabilities. | 3 / 3 |
Completeness | Explicitly answers both what ('bidirectional messaging, horizontal scaling with Redis, presence tracking, room management') and when ('Use when building real-time communication systems with WebSockets or Socket.IO'). | 3 / 3 |
Trigger Term Quality | Includes natural keywords users would say: 'WebSockets', 'Socket.IO', 'real-time communication', 'Redis', 'presence tracking', 'room management' - good coverage of domain-specific terms. | 3 / 3 |
Distinctiveness Conflict Risk | Clear niche focused on WebSockets/Socket.IO real-time systems with specific triggers like 'Redis', 'presence tracking', 'room management' - unlikely to conflict with general web development skills. | 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 a high-quality skill that efficiently covers WebSocket/Socket.IO implementation with excellent actionability. The code examples are complete and production-ready, the workflow includes proper validation checkpoints, and the progressive disclosure via the reference table is well-designed. The MUST DO/MUST NOT DO constraints provide clear guardrails without being verbose.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient, assuming Claude's competence with WebSocket concepts. No unnecessary explanations of what WebSockets are or how libraries work—jumps straight to actionable patterns and code. | 3 / 3 |
Actionability | Provides fully executable, copy-paste ready code examples for both server and client implementations. Includes specific commands for testing (wscat), concrete configuration values, and complete working examples with auth, rooms, and Redis scaling. | 3 / 3 |
Workflow Clarity | Clear 6-step workflow with explicit validation checkpoints: 'Validate locally' step includes specific test commands and what to verify; 'Scale' step requires Redis verification before enabling adapter. Feedback loops are implicit but present in the iterative nature of validation steps. | 3 / 3 |
Progressive Disclosure | Excellent structure with a reference table pointing to one-level-deep topic files (protocol.md, scaling.md, etc.) with clear 'Load When' guidance. Main content stays focused on core workflow and essential examples without becoming monolithic. | 3 / 3 |
Total | 12 / 12 Passed |
