Validation for skill structure
Discovery
50%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
The description effectively identifies specific capabilities and targets a clear product niche (Eight Sleep pods), making it distinctive. However, it critically lacks explicit trigger guidance ('Use when...') which would help Claude know when to select this skill, and could benefit from additional natural language terms users might say when wanting to control their smart bed.
Suggestions
Add a 'Use when...' clause with trigger terms like 'Eight Sleep', 'smart bed', 'bed temperature', 'sleep pod', or 'mattress temperature'
Include common user phrases such as 'warm up my bed', 'adjust sleep temperature', or 'set bed alarm' to improve trigger term coverage
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: 'status, temperature, alarms, schedules' - these are distinct, actionable capabilities for controlling Eight Sleep pods. | 3 / 3 |
Completeness | Describes what it does (control pods with status, temperature, alarms, schedules) but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill. | 1 / 3 |
Trigger Term Quality | Includes the brand name 'Eight Sleep' and 'pods' which users would say, but missing common variations like 'smart mattress', 'bed temperature', 'sleep tracking', or 'smart bed'. | 2 / 3 |
Distinctiveness Conflict Risk | Very clear niche - 'Eight Sleep pods' is a specific product/brand that would not conflict with other skills. The combination of brand name and specific features makes it highly distinctive. | 3 / 3 |
Total | 9 / 12 Passed |
Implementation
87%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-crafted, concise skill that provides actionable CLI commands for Eight Sleep pod control. It respects Claude's intelligence by avoiding unnecessary explanations and organizes commands logically. The only weakness is the lack of explicit error handling or validation guidance for potentially disruptive operations like temperature changes.
Suggestions
Add brief error handling guidance (e.g., what to do if auth fails or rate limit is hit)
Consider adding a validation step before destructive operations: 'Run `eightctl status` to verify current state before making changes'
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely lean and efficient. No unnecessary explanations of what Eight Sleep is or how CLI tools work. Every line provides actionable information. | 3 / 3 |
Actionability | Provides concrete, copy-paste ready commands for all common operations. Commands are specific and executable (e.g., `eightctl temp 20`, `eightctl alarm list|create|dismiss`). | 3 / 3 |
Workflow Clarity | For a simple CLI wrapper skill, the commands are clear, but the 'confirm before changing temperature or alarms' note suggests destructive operations without explicit validation steps or feedback loops for error handling. | 2 / 3 |
Progressive Disclosure | For a simple skill under 50 lines with a single purpose (CLI control), the content is well-organized into logical sections (Auth, Quick start, Common tasks, Notes) without needing external references. | 3 / 3 |
