action-cable
Setup and use ActionCable for real-time features in Rails applications using WebSockets. Use when implementing real-time updates, live notifications, broadcasting changes, or when the user mentions WebSockets, ActionCable, channels, broadcasting, or Turbo Streams over cable.

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 strong skill description with excellent trigger term coverage and completeness, clearly answering both what the skill does and when to use it. The main weakness is that the 'what' portion could be more specific about concrete actions (e.g., creating channels, configuring subscriptions, setting up broadcasts) rather than the somewhat general 'setup and use ActionCable for real-time features'.
Suggestions
Expand the capability description with more specific actions, e.g., 'Create channels, configure subscriptions, broadcast messages, and stream real-time updates using ActionCable in Rails applications.'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (ActionCable, Rails, WebSockets) and mentions some actions ('setup and use', 'real-time features'), but doesn't list multiple specific concrete actions like 'create channels, configure subscriptions, broadcast messages, stream updates'. | 2 / 3 |
Completeness | Clearly answers both 'what' (setup and use ActionCable for real-time features in Rails) and 'when' with an explicit 'Use when...' clause listing specific trigger scenarios and terms. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'real-time updates', 'live notifications', 'broadcasting', 'WebSockets', 'ActionCable', 'channels', 'Turbo Streams over cable'. These are terms users would naturally use when needing this skill. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with a clear niche: ActionCable + Rails + WebSockets is a very specific technology combination. The trigger terms like 'ActionCable', 'channels', 'broadcasting', and 'Turbo Streams over cable' are unlikely to conflict with other skills. | 3 / 3 |

Implementation
64%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a solid, actionable skill with good executable code examples covering the key ActionCable components and Turbo Streams broadcasting patterns. Its main weaknesses are the lack of a clear sequential setup workflow with validation checkpoints and some minor verbosity in explaining things Claude already knows. The content would benefit from a step-by-step 'getting started' flow and explicit verification steps.
Suggestions
Add a sequential setup workflow (e.g., '1. Add connection auth → 2. Create channel → 3. Add client subscription → 4. Verify connection in browser console → 5. Test broadcast') with explicit validation checkpoints.
Remove the empty base Channel class example and the overview sentence explaining what ActionCable is—Claude already knows these.
Consider splitting configuration and security considerations into a referenced file to keep the main skill focused on the actionable setup and broadcasting patterns.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Generally efficient but includes some unnecessary filler like 'Base channel class for all application channels' and the overview sentence explaining what ActionCable is. The empty base Channel class example adds little value since Claude already knows this pattern. | 2 / 3 |
Actionability | Provides fully executable, copy-paste ready code examples for connection setup, JavaScript initialization, Turbo Streams broadcasting (append/replace/remove), configuration files, and a concrete organization-scoped notification example with both view and controller code. | 3 / 3 |
Workflow Clarity | The content is organized by component but lacks a clear sequential workflow for setting up ActionCable from scratch. There are no validation checkpoints—e.g., no steps to verify the WebSocket connection is working, no troubleshooting flow if broadcasting fails, and the debugging section is separate rather than integrated into a setup workflow. | 2 / 3 |
Progressive Disclosure | Content is well-structured with clear headers and sections, but everything is inline in a single file. The configuration, security considerations, and debugging sections could be referenced out. For a skill of this length (~120 lines of content), it's borderline but leans toward needing better separation or at least signposted references for advanced topics. | 2 / 3 |
