Quality

Content

79%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

This is a strong, actionable skill with excellent code examples covering multiple real-world Action Cable patterns. The main weaknesses are the lack of explicit validation/debugging workflows for WebSocket connections and the monolithic structure that could benefit from splitting advanced topics into separate files.

Suggestions

Add a troubleshooting/debugging section with explicit validation steps (e.g., how to verify connections are working, common error messages and fixes)

Split advanced topics (Turbo Streams integration, Stimulus controllers, performance tuning) into separate reference files linked from the main skill

Add explicit verification commands or browser console checks to confirm successful WebSocket connections

Dimension	Reasoning	Score
Conciseness	The skill is lean and efficient, providing executable code examples without explaining what WebSockets or Action Cable are. Every section delivers actionable patterns without unnecessary preamble.	3 / 3
Actionability	All code examples are complete and executable - from configuration files to full channel implementations with both Ruby and JavaScript sides. The patterns are copy-paste ready with real-world scenarios.	3 / 3
Workflow Clarity	While individual patterns are clear, the skill lacks explicit validation steps for the multi-step process of setting up Action Cable. The checklist at the end is helpful but doesn't include verification commands or feedback loops for debugging connection issues.	2 / 3
Progressive Disclosure	The content is well-organized with clear sections, but at ~400 lines it's quite long for a single file. Advanced topics like performance tuning, Turbo Streams integration, and Stimulus controllers could be split into separate reference files.	2 / 3

Description

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 uses third person voice, provides specific concrete actions, includes comprehensive trigger terms covering both technical jargon and natural user language, and has an explicit 'Use when...' clause that clearly delineates when to select this skill.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions: 'live updates, chat features, notifications, real-time dashboards' - these are distinct, actionable capabilities that clearly describe what the skill does.	3 / 3
Completeness	Clearly answers both what ('Implements real-time features with Action Cable and WebSockets') and when ('Use when adding live updates, chat features, notifications, real-time dashboards, or when user mentions Action Cable, WebSockets, channels, or real-time').	3 / 3
Trigger Term Quality	Excellent coverage of natural terms users would say: 'Action Cable', 'WebSockets', 'channels', 'real-time', 'live updates', 'chat features', 'notifications', 'dashboards' - covers both technical terms and common user language.	3 / 3
Distinctiveness Conflict Risk	Clear niche focused on Rails-specific real-time technology (Action Cable) with distinct triggers; unlikely to conflict with general WebSocket skills or other Rails skills due to specific domain focus.	3 / 3
	Total	12 / 12 Passed
